DANGER

Observe the following precautions when working on or around your IT rack system:

v Heavy equipment—personal injury or equipment damage might result if

mishandled.

v Always lower the leveling pads on the rack cabinet.

v Always install stabilizer brackets on the rack cabinet.

v To avoid hazardous conditions due to uneven mechanical loading, always install

the heaviest devices in the bottom of the rack cabinet. Always install servers and

optional devices starting from the bottom of the rack cabinet.

v Rack-mounted devices are not to be used as shelves or work spaces. Do not

place objects on top of rack-mounted devices.

v Each rack cabinet might have more than one power cord. Be sure to disconnect

all power cords in the rack cabinet when directed to disconnect power during

servicing.

v Connect all devices installed in a rack cabinet to power devices installed in the

same rack cabinet. Do not plug a power cord from a device installed in one rack

cabinet into a power device installed in a different rack cabinet.

v An electrical outlet that is not correctly wired could place hazardous voltage on

the metal parts of the system or the devices that attach to the system. It is the

responsibility of the customer to ensure that the outlet is correctly wired and

grounded to prevent an electrical shock.

(R001 part 1 of 2)

CAUTION:

v Do not install a unit in a rack where the internal rack ambient temperatures will

exceed the manufacturer’s recommended ambient temperature for all your

rack-mounted devices.

v Do not install a unit in a rack where the air flow is compromised. Ensure that air

flow is not blocked or reduced on any side, front, or back of a unit used for air flow

through the unit.

v Consideration should be given to the connection of the equipment to the supply

circuit so that overloading of the circuits does not compromise the supply wiring or

overcurrent protection. To provide the correct power connection to a rack, refer to

the rating labels located on the equipment in the rack to determine the total power

requirement of the supply circuit.

v (For sliding drawers) Do not pull out or install any drawer or feature if the rack

stabilizer brackets are not attached to the rack. Do not pull out more than one

drawer at a time. The rack might become unstable if you pull out more than one

drawer at a time.

v (For fixed drawers) This drawer is a fixed drawer and must not be moved for

servicing unless specified by the manufacturer. Attempting to move the drawer

partially or completely out of the rack might cause the rack to become unstable or

cause the drawer to fall out of the rack.

detach the rack cabinet from the suite.

– Inspect the route that you plan to take when moving the rack to

eliminate potential hazards.

– Verify that the route that you choose can support the weight of the

loaded rack cabinet. Refer to the documentation that came with your

rack cabinet for the weight of a loaded rack cabinet.

– Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.).

– Ensure that all devices, shelves, drawers, doors, and cables are secure.

– Ensure that the four leveling pads are raised to their highest position.

– Ensure that there is no stabilizer bracket installed on the rack cabinet

during movement.

– Do not use a ramp inclined at more than 10 degrees.

– Once the rack cabinet is in the new location, do the following:

- Lower the four leveling pads.

- Install stabilizer brackets on the rack cabinet.

- If you removed any devices from the rack cabinet, repopulate the rack

cabinet from the lowest position to the highest position.

– If a long distance relocation is required, restore the rack cabinet to the

configuration of the rack cabinet as you received it. Pack the rack

cabinet in the original packaging material, or equivalent. Also, lower the

leveling pads to raise the casters off of the pallet and bolt the rack

cabinet to the pallet.

xxii SAN24B-4 Installation, Service, and User’s Guide

Chapter 1. Introducing the SAN24B-4 switch

The IBM System Storage SAN24B-4 is a cost-effective and highly-scalable 1, 2, 4,

or 8 Gbit/sec switch, designed for small to mid-sized businesses. It runs on the

Fabric Operating System (Fabric OS) and is compatible with other IBM switches,

which enables seamless connectivity into heterogeneous SAN environments. This

switch is a dual purpose device that you can use either as a full-functioned switch

or as an N_Port ID Virtualization (NPIV) access gateway. When functioning as an

access gateway, the it provides a single platform for all SAN connectivity. Because

the switch is scalable, you can use it as a foundation switch for a small storage

area network (SAN) and continue to use it as a building block as the SAN grows.

This chapter provides the following information:

v “Features and functions of the switch”

v “Supported connectivity” on page 2

v “Port side of the switch” on page 2

v “Nonport side of the switch” on page 3

v “Additional port activation” on page 3

v “ISL Trunking groups” on page 3

v “Supported optional features” on page 4

Features and functions of the switch

The switch provides the following features and functions:

v 1U chassis–The chassis can be installed as a standalone unit or mounted in a

standard Electronic Industries Association (EIA) 48.26 cm (19 in.) cabinet.

v One built-in fixed power unit (not field-replaceable)

v Three built-in fans (none are field-replaceable). The switch is cooled by a

redundant fan configuration, which allows continued operation with a single fan

failure.

v On-demand scaling of 8 to 24 8 Gbit/sec ports

v ASIC technology supporting 1, 2, 4 and 8Gbit/sec auto-sensing Fibre Channel

ports.

v Ability to operate as either a full-functioned switch or an NPIV access gateway.

v RJ45 Ethernet management port that in conjunction with EZSwitchSetup,

supports switch IP address discovery and configuration.

v Uses EZSwitchSetup wizard for setup and basic configuration.

v Single motherboard design with a 667 MHz PowerPC® 440EPx Reduced

Instruction Set Computer (RISC) CPU with integrated peripherals.

v Offers forward and backward compatibility with IBM System Storage SAN switch

models, 1, 2, 4 and 8 Gbps auto-sensing capability, as well as Advanced Fabric

Services and management tools.

v Enables interoperability between IBM System Storage b-type and m-type SAN

switches and directors.

v Inter-Switch-Link Trunking (licensable) enables up to eight ports (at 1G, 2G, 4G,

or 8G speeds) between a pair of switches to be combined to form a single,

logical ISL switch with a speed of up to 64 Gbits/sec (128 Gbits/sec full duplex)

for optimal bandwidth utilization and load balancing.

v Intelligent management and monitoring with Web Tools, Fabric Watch, and

Performance Monitor.

v Adaptive Networking Services uses network intelligence to anticipate congestion

and to dynamically make adjustments in the fabric so that application traffic

continues to flow

v Dynamic Path Selection (DPS) optimizes fabric-wide performance and load

balancing by automatically routing data to the most efficient available path in the

fabric.

v Light emitting diodes (LEDs) to indicate system power, system status, Ethernet

speed and link status, and port status.

Supported connectivity

Specific details on supported operating systems, servers, and devices, storage

products attachability, SAN connectivity products, and configuration options can be

found in the interoperability matrices at the following web site: www.ibm.com/servers/storage/support/san.

Port side of the switch

Figure 1 shows the port side of the switch. All LEDs are on the port side of the

switch: the nonport side is used to allow the free flow of air. The switch enclosure

has forced-air cooling, with the fans pushing the air from the nonport side of the

chassis through the enclosure, exhausting to the port side. For a complete

description of the locations and interpretations of these LEDs, see “Interpreting LED

activity” on page 19.

Nonport side of the switch

The nonport side of the switch is used solely for air flow. There are no features on

this side.

Supported fabric configurations

The switch is supported as an edge device in fabrics of up to 239 switches.

Additional port activation

The switch can be purchased with 8, 16, or 24 licensed ports. As your needs

increase, you can activate unlicensed ports by purchasing and installing the

additional 8 port activation feature. After it has been installed, the license appears

under the licenseShow command as Ports on Demand license.

The additional ports are ready to be unlocked in the switch firmware. The license

might be part of the licensed paper pack supplied with switch software, or you can

purchase the license separately from IBM, who will provide you with a key to unlock

it.

By default, ports 0 through 7 are enabled on the switch. To enable ports 8 through

16, install a Ports on Demand license key. To enable ports 16 through 24, install

another Ports on Demand license.

After you have installed the license keys, you must enable the ports. You can do so

without disrupting switch operation by using the portEnable command on each port

individually. Alternatively, you can disable and reenable the switch to activate all

ports simultaneously.

To install the additional port activation license, you can either use the supplied

license key or generate a license key. Typically the switch is shipped with a paper

pack that specifies the transaction key to use with the Software License Keys link.

Use this transaction key at the following Web site: http://www.ibm.com/servers/storage/support/san.

1. On that page, from the Product list, select your product.

2. Select Download from the Support & downloads section.

3. From the page that is generated, select License request in the Tool/utility

section.

4. Follow the instructions on that page to generate the key. You can also use this

site to generate other license keys for your switch.

ISL Trunking groups

The switch supports Interswitch Link (ISL) Trunking as a licensed feature. When this

feature is enabled, create Trunked groups of up to 8 contiguous ports. This means

that you can create up to three trunked groups that contain 8 ports each. The Fibre

Channel ports on the switch are numbered from left to right and color-coded within

groups of eight to indicate which ports you can combine into trunked groups.

Chapter 1. Introducing the SAN24B-4 switch 3



v A–Trunk Group 1: ports 0 through 7

v B–Trunk Group 2: ports 8 through 15

v C–Trunk Group 3: ports 16 through 23

Note: ISL Trunking is optional software that allows you to create trunking groups of

ISLs between adjacent switches. For more information about trunking, refer

to the Fabric OS Administrator’s Guide.

Supported optional features

The switch supports the following optional software, which you can activate by

purchasing the corresponding license key:

v Extended Fabric–allows implementation of long distance dynamic (LD) and long

distance static (LS) distance levels. This feature extends SAN fabrics beyond the

Fibre Channel standard 10 km by optimizing the internal switch buffers to

maintain performance on ISLs at distances up to 500 kilometers.

v Fabric Watch–monitors mission-critical switch operations. This feature is

designed to enable real-time proactive awareness of the health, performance,

and security of each switch. It automatically alerts network managers to problems

and helps avoid costly failures by providing:

– Real-time tracking of numerous fabric and switch elements

– Automatic event notifications when switch and fabric elements exceed

thresholds

– Security, availability, and congestion monitoring thresholds and alerts

v Adaptive Networking– provides a set of capability allowing high priority

connections to obtain the bandwidth necessary for optimum performance, even in

congested environments.

v Advanced Performance Monitor–provides Performance Monitoring capability to

help identify end-to-end bandwidth usage by host/target pairs and is designed to

provide information for capacity planning.

v Trunking Activation–designed to enable Fibre Channel packets to be efficiently

distributed across multiple Inter-Switch connections (links) between two SAN

b-type fabric switches, while preserving in-order delivery. ISL Trunking is

supported between any of the supported 2, 4, or 8 Gbps b-type models. Both

SAN b-type fabric switches must have ISL Trunking activated.

In addition, customers can order a set of optional features bundled into one

orderable feature, the B24 Enterprise Package. This bundled feature consists of

one of each of Fabric Watch, Trunking Activation, Advanced Performance Monitor,

Adaptive Networking, and two 8-Port Activations.

For more information on the use of these features, refer to the Fabric OS

Administrator’s Guide.

Chapter 2. Installing and configuring the switch

You can install the switch in either of two ways:

v As a stand-alone unit on a flat surface

v In an Electronic Industries Association (EIA) cabinet using a slide-rail rack mount

kit, which is provided with the switch. When you mount the switch into a slide-rail

rack, you can mount the chassis to slide from either the port side or the non-port

side.

The SAN24B-4 can be configured and operated as either a SAN fabric switch or as

an Access Gateway. The configuration instructions in this publication are for the

SAN24B-4 to operate as a switch. The installation instructions in this document

apply to both Switch and Access Gateway modes. To configure and operate the

SAN24B-4 in Access Gateway mode, refer to the IBM System Storage SAN24B-4

Access Gateway Quick Start Guide and the Access Gateway Administrator's Guide.

Attention: When you enable Access Gateway mode, you disable the ability for

the SAN24B-4 to operate as a switch. Access Gateway mode and switch mode are

mutually exclusive. If you want to use the SAN24B-4 as a switch at a later time, you

will need to disable Access Gateway mode and enable switch mode. Changing

between Access Gateway and Switch modes is a data disruptive operation. It is

strongly recommended that you disable the switch from the command line interface

before enabling or disabling Access Gateway mode.

Installation and safety considerations

Use this section to prepare your site for a safe and successful installation.

Attention: Although the switch has been designed for customer installation and

replacement procedures, you must first ensure that the rack into which the switch is

to be installed is also customer accessible. If it is not, then only trained personnel

can install and service these switches in such a rack.

Attention: Read the “Safety and environmental notices” on page ix

before attempting any installation or maintenance procedures.

The switch can be installed either as a free-standing unit, or installed in an EIA

cabinet, using an optional slide-rail rack mount kit. When mounting into a slide-rail

rack, you can mount the chassis to slide from either the port side or the nonport

side.

Electrical considerations

To install and operate the switch successfully, ensure the following:

v The primary outlet is correctly wired, protected by a circuit breaker, and grounded

in accordance with local electrical codes.

v The supply circuit, line fusing, and wire size are adequate, as specified by the

electrical rating on the switch nameplate.

v The power supply standards provided in “Power supply specifications” on page

34 are met.

Environment considerations

For successful installation and operation of the switch, ensure that the following

environmental requirements are met:

v At a minimum, adequate cooling requires that you install the switch with the

nonport side, which contains the air intake vents, facing the cool-air aisle.

v All equipment in the rack should force air in the same direction to avoid intaking

exhaust air.

v A minimum of 680 l/min (24 cubic ft/min) of air flow is available to the air intake

vents on the nonport side of the switch.

v The ambient air temperature does not exceed 40° C (104° F) while the switch is

operating.

Cabinet considerations

Attention: See “Rack safety” on page xiv for danger and caution notices related

to product installations in racks or cabinets.

For successful installation and operation of the switch in a cabinet, ensure that the

following cabinet requirements are met:

v The cabinet must be a standard EIA cabinet.

v Plan a cabinet space that is 1 rack unit 4.45 cm (1.75 in.) high, 48.3 cm (19 in)

wide.


v Ground all equipment in the cabinet through a reliable branch circuit connection

and maintain ground at all times. Do not rely on a secondary connection to a

branch circuit, such as a power strip.

v Ensure that airflow and temperature requirements are met on an ongoing basis,

particularly if the switch is installed in a closed or multicabinet assembly.

v Verify that the additional weight of the switch does not exceed the cabinet’s

weight limits or unbalance the cabinet in any way.

v Secure the cabinet to ensure stability in case of unexpected movement, such as

an earthquake.

Installing a stand-alone switch

To install the switch as a stand-alone unit, use the following procedure:

1. Unpack the switch and verify the items listed in “Items included with the switch”

on page 5

2. Apply the adhesive rubber feet. Applying the rubber feet onto the switch helps

prevent the switch from sliding off the supporting surface.

a. Clean the indentations at each corner of the bottom of the switch to ensure

that they are free of dust or other debris that might lessen the adhesion of

the feet.

b. With the adhesive side against the chassis, place one rubber foot in each

indentation and press into place.

3. Place the switch on a flat, sturdy surface.

4. Provide power to the switch as described in “Powering the switch on and off” on

page 19.

Attention: Do not connect the switch to the network until the IP address is

correctly set. For instructions on how to set the IP address, see “Configuring the

switch” on page 14.

Installing the switch into an EIA cabinet

Attention: Although the switch has been designed for customer installation and

replacement procedures, you must first ensure that the rack into which the switch is

to be installed is also customer accessible. If it is not, then only trained personnel

can install and service these switches in such a rack.

Attention: Read the “Safety and environmental notices” on page ix

before attempting any installation or maintenance procedures.

Attention: Refer to “Rack safety” on page xiv for danger and caution notices

related to rack and cabinet installations.

You can install the rack mount kit in either of two ways:

v To allow the port side of the switch to slide out of the exhaust-air side of the

cabinet. In this installation, the port side of the switch is flush with the edge of the

cabinet.

v To allow the non-port side of the switch to slide out the cool-air side of the

cabinet. In this installation, the port side of the switch is set 7.62 cm (3 in.) back

from the edge of the cabinet, allowing a more gradual bend in the fiber optic

cables.

Chapter 2. Installing and configuring the switch 7

Time required

Approximately 30 minutes

Cables can be organized and managed in a variety of ways: for example, using

cable channels on the sides of the cabinet or patch panels to minimize cable

management. Following is a list of recommendations:

v Plan for rack space required for cable management before installing the switch.

v Leave at least 1 meter (3.28 ft) of slack for each port cable. This provides room

to remove and replace the switch, allows for inadvertent movement of the rack,

and helps prevent the cables from being bent to less than the minimum bend

radius.

v If you are using Brocade ISL Trunking, consider grouping cables by trunking

groups. The cables used in trunking groups must meet specific requirements, as

described in the Fabric OS Administrator’s Guide.

v For easier maintenance, label the fiber optic cables and record the devices to

which they are connected.

v Keep LEDs visible by routing port cables and other cables away from the LEDs.

v Use hook-and-loop fasteners to secure and organize fibre optic cables. Do not

use tie wraps on fiber optic cables, because wraps are easily overtightened and

can damage the optic fibers.

Configuring the switch

You must configure the switch to ensure correct operation within a network and

fabric. For instructions about how to configure the switch to operate in a fabric that

contains switches from other vendors, refer to the Fabric OS Administrator's Guide.

For more information about the commands used in this procedure, refer to the

Fabric OS Command Reference Manual.

v “Using the EZSwitch setup (optional)”

v “Providing power to the switch”

v “Creating a serial connection” on page 15

v “Setting the switch IP address” on page 15

v “Setting the date and time” on page 16

Using the EZSwitch setup (optional)

Once you have set up the switch in a rack or as a stand-alone switch, it is time to

give it power and a basic configuration. If you are going to use the switch in a

single-switch setup, you can use EZSwitchSetup to complete the basic

configuration. See the EZSwitchSetup CD included with the accessory kit for more

information. You can also use the SAN24B-4 Quick Start Guide. If you do not want

to use EZSwitch Setup, use the instructions in following sections.

Providing power to the switch

To provide power to the switch:

1. Connect the power cord to the power receptacle on the port side of the switch,

and then to the power source. Ensure that the cord has a minimum service loop

of 15 cm (6 in.) available and is routed to avoid stress.

The switch does not have a on/off power switch. This means that power is

supplied to the switch as soon as you connect it to an AC power source.

The status LEDs display amber until POST is complete, and then change to

green. The switch usually requires from 1 to 3 minutes to boot and complete

POST.

2. After POST is complete, verify that the switch power and status LEDs on the left

of the port side of the switch are green.


Creating a serial connection

You will perform all basic configuration tasks in this guide using a serial connection.

To create a serial connection to the switch, complete the following steps:

1. Connect the serial cable to the serial port on the switch and to an RS-232 serial

port on the workstation.If the serial port on the workstation is RJ-45 instead of RS-232, remove the

adapter on the end of the serial cable and insert the exposed RJ-45 connector

into the RJ-45 serial port on the workstation.

2. Disable any serial communication programs running on the workstation.

3. Open a terminal emulator application (such as HyperTerminal on a PC, or

TERM, TIP, or Kermit in a UNIX® environment), and configure the application as

follows:

v In a Windows® environment:

Bits per second 9600

Databits 8

Parity None

Stop bits 1

Flow control None

v In a UNIX environment, type the following string at the prompt:

tip /dev/ttyb -9600If ttyb is already in use, use ttya instead and enter the following string at the

prompt:

tip /dev/ttya -9600

Setting the switch IP address

You can configure the switch with a static IP address, or you can use a DHCP

(Dynamic Host Configuration Protocol) server to set the IP address of the switch.

DHCP is enabled by default. The switch supports both IPv4 and IPv6.

Using DHCP

When using DHCP, the switch obtains its IP address, subnet mask, and default

gateway address from the DHCP server. The DHCP client can only connect to the a

DHCP server that is on the same subnet as the switch. If your DHCP server is not

on the same subnet as the switch, use a static IP address.

Setting a static IP address

1. Log into the switch using the default password, which is password.

2. Use the ipaddrset command to set the Ethernet IP address.If you are going to use an IPv4 IP address, enter the IP address in dotted

decimal notation as prompted.

Ethernet IP Address: [192.168.74.102]

If you are going to use an IPv6 address, enter the network information in

semicolon-separated notation as prompted.

switch:admin> ipaddrset -ipv6 --add 1080::8:800:200C:417A/64

IP address is being changed...Done.

3. Complete the rest of the network information as prompted.


Ethernet Subnetmask: [255.255.255.0]

Ethernet IP Address: [192.168.74.102]

Ethernet Subnetmask: [255.255.255.0]

4. Enter off to Disable DHCP when prompted.

DHCP [OFF]: off

Setting the date and time

The switch maintains the current date and time inside a battery-backed real-time

clock (RTC) circuit. Date and time are used for logging events. Switch operation

does not depend on the date and time; a switch with an incorrect date and time

value still functions properly. However, because the date and time are used for

logging, error detection, and troubleshooting, you should set them correctly.

Setting the date

1. If you are not already logged into the switch; do so now using the default

password, which is password.

2. Enter the date command, using the following syntax:

date "mmddHHMMyy"

The values represent the following:

v mm is the month; valid values are 01 through 12

v dd is the date; valid values are 01 through 31

v HH is the hour; valid values are 00 through 23

v MM is minutes; valid values are 00 through 59

v yy is the year; valid values are 00 through 99 (values greater than 69 are

interpreted as 1970 through 1999, and values less than 70 are interpreted as

2000-2069)

switch:admin> date

Fri Sep 29 17:01:48 UTC 2007

switch:admin> date "0927123007"

Thu Sep 27 12:30:00 UTC 2007

switch:admin>

Setting time zones

You can set the time zone for a switch by name. You can specify the setting using

country and city or time zone parameters.

If the time zone is not set with the new options, the switch retains the offset time

zone settings. The tsTimeZone command also includes an option to revert to the

prior time zone format. For more information about the tstimezone [--old] option,

see the Fabric OS Command Reference Manual.

You can set the time zone for a switch using the tsTimeZone command. The

tsTimeZone command allows you to perform the following tasks:

v Display all of the time zones supported in the firmware

v Set the time zone based on a country and city combination or based on a time

zone ID such as PST

The time zone setting has the following characteristics:

v You can view the time zone settings. However, only those with administrative

permissions can set the time zones.

v The tsTimeZone setting automatically adjusts for Daylight Savings Time.


v Changing the time zone on a switch updates the local time zone setup and is

reflected in local time calculations.

v By default, all switches are in the GMT time zone (0,0). If all switches in a fabric

are in one time zone, it is possible for you to keep the time zone setup at the

default setting.

v System services that have already started will reflect the time zone changes only

after the next reboot.

v Time zone settings persist across failover for high availability.

The following procedure describes how to set the time zone for a switch. You must

perform the procedure on all switches for which the time zone must be set.

However, you only need to set the time zone once on each switch, because the

value is written to nonvolatile memory.



2. Enter the tsTimeZone command as follows:

switch:admin> tstimezone [--interactive]/ [, timezone_fmt]

Use timezone_fmt to set the time zone by Country/City or by time zone ID,

such as PST.The following example shows how to display the current time zone setup and

how to change the time zone to US/Central.

switch:admin> tstimezone

Time Zone : US/Pacific

switch:admin> tstimezone US/Central

switch:admin> tstimezone

Time Zone : US/Central

The following procedure describes how to set the current time zone using

interactive mode to Pacific Standard Time.

1. Type the tsTimeZone command as follows:

switch:admin> tstimezone --interactive

2. You are prompted to select a general location.

Please identify a location so that time zone rules can be set correctly.

3. Enter the appropriate number or Ctrl-D to quit.

4. At the prompt, select a country location.

5. At the prompt, enter the appropriate number to specify the time zone region or

Ctrl-D to quit.

Synchronizing local time using NTP

You can synchronize the local time of the principal or primary fabric configuration

server (FCS) switch to a maximum of eight external network time protocol (NTP)

servers. To keep the time in your SAN current, it is recommended that the principal

or primary FCS switch has its time synchronized with at least one external NTP

server. The other switches in the fabric will automatically take their time from the

principal or primary FCS switch.

All switches in the fabric maintain the current clock server value in non-volatile

memory. By default, this value is the local clock server <LOCL> of the principal or

primary FCS switch. Changes to the clock server value on the principal or primary

FCS switch are propagated to all switches in the fabric.


For more information on using an NTP server, and IPv6 considerations, see the

Fabric OS Administrator’s Guide.



2. Enter the tsClockServer command:

switch:admin> tsclockserver "<ntp1;ntp2>"

where ntp1 is the IP address or DNS name of the first NTP server, which the

switch must be able to access. The second ntp2 is the second NTP server and

is optional. The operand “<ntp1;ntp2>” is optional; by default, this value is

LOCL, which uses the local clock of the principal or primary switch as the clock

server.

The tsClockServer command accepts multiple server addresses in either IPv4, IPv6,

or DNS name formats. When multiple NTP server addresses are passed,

tsclockserver sets the first obtainable address as the active NTP server. The rest

will be stored as backup servers that can take over if the active NTP server fails.

The principal or primary FCS switch synchronizes its time with the NTP server

every 64 seconds.

switch:admin> tsclockserver

LOCL

switch:admin> tsclockserver "132.163.135.131"

switch:admin> tsclockserver

132.163.135.131

switch:admin>

The following example shows how to set up more than one NTP server using a

DNS name:

switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net"

Updating Clock Server configuration...done.

Updated with the NTP servers

Changes to the clock server value on the principal or primary FCS switch

are propagated to all switches in the fabric.

Powering the switch on and off

See Chapter 2, “Installing and configuring the switch,” on page 5 for initial setup

instructions before powering the switch on for the first time. Once the switch has

been properly configured, follow these instructions to power the switch on and off.

The SAN24B-4 does not have an AC power switch. To power on the SAN24B-4,

connect the power cable to the AC receptacle on the switch and to a power source.

The switch runs POST by default each time it is powered on, reset, or rebooted,

and requires a minimum of three minutes to run. To end the flow of power to the

switch, remove the power cord from the power source.

Interpreting LED activity

System activity and status can be determined through the activity of the LEDs on

the switch. All LEDs are located on the port side of the switch. There are three

possible LED states: no light, a steady light, and a flashing light. The steady lights

and flashing lights can be green or amber. The LEDs flash either of these colors

during boot, POST, or other diagnostic tests. This is normal and does not indicate a

problem unless the LEDs do not indicate a healthy state after all boot processes

and diagnostic tests are complete.

The switch has the following LEDs:

v System power LED–One LED (green) to indicate system power

v System status LED–One LED (green/amber) to indicate system status

v Ethernet status LEDs–Two LEDs to indicate speed and link status

v Port status LEDs–24 LEDs (green/amber) to indicate status for each port

POST and boot specifications

When the switch is turned on or rebooted, the switch performs POST. Total boot

time with POST is up to 3 minutes. POST can be omitted after subsequent reboots

by using the fastboot command or entering the diagDisablePost command to

persistently disable POST.

For more information about these commands, refer to the Fabric OS Command

Reference Manual.

POST

The success or failure results of the diagnostic tests that run during POST can be

monitored through the error log or the command line interface.

POST includes the following steps:

1. Preliminary POST diagnostics are run.

2. Operating system is initialized.

3. Hardware is initialized.

4. Diagnostic tests are run on several functions, including circuitry, port

functionality, memory, statistics counters, and serialization.

Boot

In addition to POST, boot includes the following steps after POST is complete:

1. Universal port configuration is performed.

2. Links are initialized.

3. Fabric is analyzed, and if any ports are connected to other switches, the switch

participates in a fabric configuration.

4. Switch obtains a domain ID and assigns port addresses.

5. Unicast routing tables are constructed.

6. Normal port operation is enabled.


Interpreting POST results

POST is a system check that is performed each time the switch is powered on,

rebooted, or reset. During POST, the LEDs flash amber and green. Any errors that

occur during POST are listed in the error log.

To determine that POST completed successfully and whether or not any errors were

detected:

1. Verify that the switch LEDs indicate that all components are healthy. See

Table 4 on page 21 through Table 7 on page 23 for the description and

interpretation of LED patterns. If one or more LEDs do not display a healthy

state, verify that the LEDs on the switch are not set to “beacon”; use the

switchShow command to detect if beaconing is active.

2. Verify that the switch prompt displays on the terminal of a computer workstation

connected to the switch. If there is no switch prompt when POST completes,

press Enter. If the switch prompt still does not display, try opening another

telnet session or accessing through another management tool. If this is not

successful, the switch did not successfully complete POST; contact IBM Service

for repair.

3. Review the switch system log for errors. Any errors detected during POST are

written to the system log, which is accessible through the errShow command.

For information about all referenced commands, and on accessing the error log,

refer to Fabric OS Administrator’s Guide. For information about error messages,

refer to the Fabric OS System Error Message Reference Manual.

Switch FRU units

The only parts for this switch that are field replaceable are the SFPs. The entire

switch is a FRU. The fan units and power supply are not field replaceable in this

switch.

Maintaining the switch

The switch does not require any regular physical maintenance; it was designed to

minimize the chance of failure. Ensure that the environmental conditions, described

in “Environment considerations” on page 6, are met. This helps prevent failure of

the switch due to distress or abuse.

Installing SFPs

The switch only supports Brocade-branded SFPs. If you use an unqualified SFP,

the switchShow command output will show the port in an Mod_Inv state. Fabric

OS will also log the issue in the system error log.

Follow these instructions to install an SFP:

1. Making sure that the bail (wire handle)�B� is in the unlocked position, place the

SFP in the correctly oriented position on the port, as shown in Figure 9 on page

25

Note: Each SFP has a 10-pad gold-plated PCB-edge connector on the bottom.

The correct position to insert an SFP into the upper row of ports is with

the gold edge down. The correct position to insert an SFP into the lower

row of ports is with the gold edge up.

2. Slide the SFP into the port until you feel it click into place; then close the bail.

2. Remove the cable from the SFP, as shown in section 2.

3. Pull the bail (wire handle) �D� in section 3 to release the SFP.

4. Grasping it by the bail, gently but firmly pull the SFP (�C� in section 4) out of the

port.

Attention: If the SFP you are removing does not have a bail, use a small

implement such as a screwdriver to press the release trigger beneath the port.

Non-bailed SFPs can be damaged by the removal process and are not

recommended. Refer to the interoperability matrix at the following web site:

www.ibm.com/servers/storage/support/san for a list of supported SFPs and

devices.

Testing a port, SFP, and fiber cable

The PortLoopbackTest command is used to verify the functional operation of the

switch by sending frames from the port "N" transmitter and looping them back into

the same port "N" receiver. The loopback is done at the parallel loopback path. The

path exercised in this test does not include the media or the fiber cable. However if

data transmission errors indicate that a port, SFP or cable are faulty, you can use

this command to determine whether the port is faulty. You can use those results to

isolate the problem to either the port or the SFP and cable combination. If a port is

faulty, the switch will need to be replaced. If the port is not faulty, the problem is

either with the SFP or the cable.

With this command, only one frame is transmitted and received at a time. No

external cable is required to run this test. The port LEDs flicker rapidly (green) while

the test is running.

The test performs the following operations:

1. Sets all ports for parallel loopback.

2. Creates a frame F of maximum data size (2,112 bytes).

3. Transmits the frame F through port "N".

4. Picks up the frame from the same port "N".

5. Checks the eight statistic error counters for nonzero values:ENC_in, CRC_err, TruncFrm, FrmTooLong, BadEOF, Enc_out, BadOrdSet, DiscC3

6. Checks whether the transmit, receive, or class 3 receiver counters are stuck at

some value.

7. Checks whether the number of frames transmitted is not equal to the number

of frames received.

8. Repeats Steps 2 through 7 for all ports until one of the following conditions are

met:

a. The number of frames (or passcount) requested is reached.

b. All ports are marked bad.

At each pass, the frame is created from a different data type. If seven passes

are requested, seven different data types are used in the test. If eight passes

are requested, the first seven frames use unique data types, and the eighth is

the same as the first. The seven data types are:

CSPAT: 0x7e, 0x7e, 0x7e, 0x7e, ...

BYTE_LFSR: 0x69, 0x01, 0x02, 0x05, ...

CHALF_SQ: 0x4a, 0x4a, 0x4a, 0x4a, ...

QUAD_NOT: 0x00, 0xff, 0x00, 0xff, ...

CQTR_SQ: 0x78, 0x78, 0x78, 0x78, ...

CRPAT: 0xbc, 0xbc, 0x23, 0x47, ...

RANDOM: 0x25, 0x7f, 0x6e, 0x9a, ....

9. If the test indicates that all ports are good, the problem is associated with

either the cable or SFP.

10. Replace the SFP with an SFP known to be good.

11. Simulate the data transmission scenario when the error occurred. If the error

does not reappear, the original SFP was defective, and should be discarded. If

the error does reappear, the cable is defective. Replace the cable and discard

the original cable.

12. Simulate the data transmission scenario again to verify that the problem does

not reappear.

Diagnostic tests

In addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the

hardware and the firmware. This includes tests of internal connections and circuitry,

fixed media, and the SFPs and cables in use.

The tests are implemented by command, either through a Telnet session or through

a terminal set up for a serial connection to the switch. Some tests require the ports

to be connected by external cables, to allow diagnostics to verify the

serializer/deserializer interface, SFP, and cable.

All diagnostic tests are run at link speeds of 1, 2, 4, and 8 Gbps, depending on the

speed of the link being tested.

Attention: Diagnostic tests can temporarily lock the transmit and receive speed of

the links during diagnostic testing.

For information about specific diagnostic tests, refer to the Fabric OS

Administrator’s Guide.

Managing the switch

You can use the management functions built into the switch to monitor the fabric

topology, port status, physical status, and other information to help you analyze

switch performance and to accelerate system debugging. The switch automatically

performs power-on-self-test (POST) each time it is turned on. Any errors are

recorded in the error log. For more information about POST, see “POST and boot

specifications” on page 23.

For information about upgrading the version of Fabric OS installed on your switch,

refer to the Fabric OS Administrator’s Guide. You can manage the switch using any

of the management options listed in Table 8.

switch can be up to 80° Celsius during switch operation. If the internal

temperature range exceeds the operating ranges of the components, the


LEDs, error messages, and Fabric Watch alerts indicate a problem. Enter the

tempShow or Fabric Watch commands to view temperature status.

Facility requirements

To ensure correct operation of the switch, the facility where the switch is in use

must meet the requirements listed in Table 11.

Table 11. Facility requirements

Type Requirements

Electrical v Primary AC input 100-240 VAC, 2.0A,

47-63 Hz; switch autosenses input voltage

v Adequate supply circuit, line fusing, and

wire size, as specified by the electrical

rating on the switch nameplate

v Correctly wired primary outlet, with circuit

protected by a circuit breaker and

grounded in accordance with local

electrical codes

Thermal v A minimum air flow of 24 cubic ft/min

available to the air intake vents on the

nonport side of the switch.

v Ambient air temperature not exceeding

40° C (104° F) while the switch is

operating

v At a minimum, adequate cooling requires

that you install the switch with the nonport

side, which contains the air intake vents,

facing the cool-air aisle

v All equipment in the rack should force air

in the same direction to avoid intaking

exhaust air

v Ensure that airflow and temperature

requirements are met on an ongoing

basis, particularly if the switch is installed

in a closed or multicabinet assembly

Cabinet (when rack-mounted) v One rack unit in a standard EIA 19-in.

(48.3 cm) cabinet

v All equipment in cabinet grounded through

a reliable branch circuit connection and

maintain ground at all times. Do not rely

on a secondary connection to a branch

circuit, such as a power strip

v Additional weight of switch not to exceed

the cabinet’s weight limits

v Cabinet secured to ensure stability in case

of unexpected movement, such as an

earthquake
