System Hardware Lesson 4


Introduction In the few sections below you will be provided with the overall knowledge

about system hardware, NCC specifications and some of the cabinet

components.

______________________________________________________________

NCC and NIDS

Workstations

NIDS is designed to support a distributed database capability, a limited fault

tolerance, and support for redundant common equipment. This ensures

maximum uptime and availability. To ensure that NIDS operates

continuously, the design is optimized to reduce single point of failure

weaknesses. Consequently, NIDS is capable of undergoing some minor

maintenance without disruption to operation of common hardware

(equipment). The workstation must be able to contact a network domain

controller at one of the NCC locations before it can successfully complete a

login to run the NIDS application.

The hardware for a typical NIDS system consists of a NIDS Control Cabinet

(NCC), and NIDS workstations communicating over an Ethernet network.

AT Database Administrator functions can also be performed from any NIDS

workstation by entering the proper user ID and password.

The data from the NIDS database and dynamic data from the various

configured external interfaces are then stored in the memory of the interface

host and distributed to each NIDS workstation and server. The NCC

exchanges data with the workstations via an Ethernet communication link

(Institute of Electrical and Electronics Engineers [IEEE] 802.3U 100

Baseband Twist Pair Cable [Base T]) operating at 10/100/1000 Megabits per

Second (Mbps).

Cabinet Specifications Lesson 4


Cabinet

Specifications

The NCC (Refer to Figure 4-1) provides for internal mounting of 40 rack-

units of equipment. The rack has exterior dimensions of 24”Wide (W) x

72”High (H) x 30”Deep (D). It has ElectroMagnetic Interference (EMI)

protection, a lockable front and rear door, and is rated for Zone 4 seismic

use. If the NCC is installed in a location which provides for under floor air

cooling, then the fans will not be required. The NCC rack is used at the

TRACON as well as the Air Traffic Control Towers (ATCT). The presence

of an NCC at the ATCT locations is based on the overall system needs as

well as local reliability needs (based on the redundancy the NCC rack

provides).

Grounding and

Shielding

The NCC rack provides two locations to attach FAA-supplied

grounding/bonding straps, near the top and bottom of the rack chassis. Each

location is paint-free and prepared for double bonding bolts in accordance

with FAA-STD-019.

WARNING: Improper grounding of NCC Rack can pose an electrocution

risk to technicians performing installation or maintenance if there is a fault

in the equipment. Additionally, it poses a risk to the performance of the

equipment. Ensure NCC Rack is properly grounded in compliance with

FAA-STD-019.

Lesson 4


Power Source The power source to the NCC is described in the Site Installation Plan and

identifies the circuit size and source. The Site Installation Plan will indicate

whether the supplied power source will be critical, essential, or commercial

power.

______________________________________________________________

Point of Entry Facility power is hardwired to two 20 Amp outlets mounted in the lower rear

of the NCC.

Technicians should be familiar with their facility power distribution and

identify the circuit breakers protecting the NCC equipment. Also, ensure

cables are labeled according to the Site Installation Plan.

______________________________________________________________

NCC Network

Wiring

External network connections to the NCC include workstation computers,

UPSs, the FTI network, and network-based interfaces such as WARP and

VOID. All of these may be connected to any available port on any of the

four NCC Network Switches.

For redundancy, it is recommended that workstations in a single location or

for a single purpose be connected to different switches. For example, if there

are four approach workstation computers at a site, each one should be

connected to a different switch. Likewise, in a room with four workstation

computers (regardless of their roles), each workstation computer should be

connected to a different switch. Spreading the workstation computers across

switches ensures that a single switch failure will not disable an entire room

or an entire job function.

______________________________________________________________

Lesson 4


NCC Power

Wiring

The NCC rack has the option of a single AC box (404000) or a dual AC box

(405000) AC connection point. Each single AC box contains two L5-30R

connectors. The dual AC box contains four L5-30R connectors. The UPSs

plug directly into the outlets. The AC box also provides terminals for dual

site AC power connections. External power cables should be routed through

the rack (along the side with all the other power cables) and terminate in the

AC interface box.

Figure 4-4, Dual Single AC Power Boxes Diagram

Prior to performing any wiring activities, ensure the power is shut down,

including de-energization verification, and locked-out/tagged-out in

accordance with FAA Order 3900.19B, Chapter 13, and Hazardous Energy

Control.

______________________________________________________________

NCC Interfaces Network interfaces such as WARP and VOID connect to any available

Network Switch port. All other interfaces are serial-based and connect to the

Interface Splitter Panel (IFSP). When connecting the IRIG-B time server to

the rack, if it is being connected to more than one device, a 600 ohm

termination is recommended.

With the exception of the IRIG-B time server, all remaining network

interfaces are converted in the NCC to RS-232 or RS-485. If the NCC is not

physically configured for a particular interface, the appropriate kit will need

to be installed before external interfaces can be connected.

Time Server Lesson 4


Description The time server accepts an Inter-Range Instrumentation Group-B (IRIG-B)

serial time code over a RG-58 coax cable from the GPS time source. Then

the Time Server makes the time update available via Network Time Protocol

(NTP) to all network-connected devices over Transmission Control

Protocol/Internet Protocol (TCP/IP). The time server is a Line Replaceable

Unit (LRU) in the event of failure. No specialized skills are required for the

physical replacement of the equipment. Tech Ops must be trained on how to

configure the time server.

The GPS Time Source provides time data in an analog IRIG-B format to

NIDS. This interface is one directional and flows from the GPS time source

to the NIDS Time Server. The Time Server then makes the NTP based time

updates available to all NIDS Clients. The time is displayed on NIDS

software. The NIDS GPS interface Connectivity Point is the Interface

Splitter Panel (IFSP) at a NIDS Control Cabinet (NCC).

The GPS Time Source transmits an analog coded time message to the NIDS

time interface (time server) with standard IRIG-B fields, as specified in IRIG

Standard 200-98. The time server transmits the time data to the NIDS

network using NTP. The old GPS related information is not stored on NIDS.

NOTE: Time Server will be covered in detail in Lesson 6, Network Devices.

Rack Mount KVM Lesson 4


Description The Rack Mount KVM consists of a KVM Console that provides a

keyboard, monitor, touchpad device, and an 8-port or 16-port KVM Switch

Module. The Rack Mount KVM with an 8-port KVM Switch Module

provides switchable connectivity to up to 8 workstations or servers. A Rack

Mount KVM with a 16-port KVM Switch Module provides switchable

connectivity to up to 16 workstations or servers.

The Rack Mount KVM is housed in a 1U-high package and rack mounted on

sliders for easy withdrawal and use from the front of the NCC. It also has a

front panel power indicator.

The Rack Mount KVM and separate power supply has no serviceable parts

and is a LRU in the event of failure. No specialized skills are required for the

physical replacement of the equipment.

Automatic Transfer Switch (ATS) Lesson 4


Description The NCC houses a single Automatic Transfer Switch (ATS) for management

of the power in the NCC from the UPS units. The ATS houses transient

voltage suppression to protect against voltage spikes and power surges.

The ATS is rack mounted inside the NCC. Indicators on the front panel of

the ATS provide visual indication of the presence of primary and secondary

power sources and indicate which source is selected for use. Observation of

these indicators can show power distribution within the NCC. Since the ATS

is not an Ethernet compatible device there is no representation for the ATS

in NIDS Mon.

The ATS has no serviceable parts and is a LRU in the event of failure. No

specialized skills are required for the physical replacement of the equipment.

Rack Mount UPS Lesson 4

Cabinet Hardware

Introduction The next few sections will familiarize you with most NCC hardware

components and provide you with the knowledge about their maintenance

procedures.

______________________________________________________________

Description For NCC racks, NIDS features the ability to support dual redundant UPS

devices to improve system availability. The rack mount UPS is mounted

inside the NCC. The UPS status is indicated through the front panel

indicators and is also reported in NIDS Mon.

Figure 4-17, Rack Mount UPS

During Normal operation, the On/Off Button and the Mode Indicator

illuminate and the front panel displays the percentage of UPS load capacity

being used by the protected equipment. This is shown on the Load Level

Indicators. The UPS monitors and charges the batteries, providing power

protection to the equipment in the event of a power outage. The main

purpose of the UPS is to provide AC line filtering to protect the facility

critical power system from the harmonics and noise generated from the

cumulative effects of the COTS equipment in the Rack.

During a power outage, the UPS beeps every 5 seconds and the On/Off

Button, Mode Indicator, and Downgraded Operation Indicator are

illuminated. The Battery Charge Level Indicators show the remaining battery

power. When power returns, the UPS reverts to Normal Mode.

When the UPS is turned off and it remains connected to a power source it

goes into Standby Mode. The Battery Charge Level Indicators and Load

Level Indicators are on and all others are off.

The UPS is equipped with a network/Ethernet card (401071) which connects

to the Mini-Slot on an Eaton 9130 UPS and is used by NIDS to obtain

SNMP information and to communicate with the UPS. This interface is also

used by the UPS software on the server to communicate with the UPS.

The UPS is a LRU in the event of failure. The battery package on the UPS is

also LRU in the event of failure. No specialized skills are required for the

physical replacement of the equipment. Tech Ops must be trained on how to

configure the UPS.

The NIDS UPS has Multiple Configuration procedures: Manual UPS

configuration, Adding a UPS, Configuring a UPS, and UPS Lan Safe (Single

LanSafe

LanSafe is power management software running on servers and workstations

providing automatic, unattended and graceful shutdown of computer systems

throughout the network during an extended power failure. It continuously

monitors the UPS status via serial, USB, and network connectivity options.

LanSafe software is running as a background process during normal

computer operation and consists of a suite of applications that contain

the Power Monitor software, Power Scope GUI and the Control Room

Console.

The Power Monitor is a background listener application that allows the

workstation computer to communicate with the UPS. The UPS Console is

the GUI used to view the UPS status, perform minor diagnostics, and view

historical logs.

______________________________________________________________

Power Loss

Should a UPS connected to a server or workstation experience a power loss,

the UPS beeps every 5 seconds, illuminating the battery LED. A counter is

started to monitor the duration of the power interruption.

In the event of a power loss, the UPS is programmed to provide short-term

protection from power interruptions, as well as gracefully shut down the

workstations after three minutes and the UPS itself in six minutes. When

power returns, the UPS reverts to Normal Mode.

After a pre-set time has elapsed without power being restored, the UPS

software initiates a graceful shutdown of the connected computer and

removes power from any connected equipment.

Software running on the UPS then waits a specified time to monitor for

power restoration. If sustained power is restored prior to that time period

elapsing, the UPS will reapply power to the computer and any other

connected equipment.

Network Switch Lesson 4

Cabinet Hardware

Description Network switches are installed to connect workstations and devices to the

NIDS LAN. This is the same Network switch used at remote sites and other

locations where a NIDS Network switch is implemented.

The Network switch has no serviceable parts and is a LRU in the event of

failure. No specialized skills are required for the physical replacement of the

equipment. Tech Ops must be trained on how to configure the Network

switch.

The Network switch has four dual-personality ports, which can be used to

connect one switch to another over fiber-optic cable. A mini-GBIC single-

mode or multi-mode module is required and plugs into one of the dual-

personality ports on each of the two switches. Although considerably more

expensive than a CAT6 cable connection, a fiber-optic connection does

provide the ability to connect switches over longer distances at gigabit

speeds. The Multi-mode module supports distances up to 3,000 feet whereas

the Single-mode module can function up to 32,000 feet without degradation.

Description The 24-port Surge Protector devices are installed on LAN connections to

protect sensitive equipment against transient Electro-Static Discharge (ESD)

and voltage surges. For the NCC, they are mounted inside the rear door of

the NCC, providing easy access to these components.

NOTE: A Surge Protector CAT6 is not a lightning arrestor and it is not

intended to serve as one.

The Surge Protector CAT6 Panel and the replaceable surge modules

mounted on the back of the panel are LRUs in the event of failure. The ports

of the Surge Protector CAT6 Panel are replaceable in pairs, two ports to a

single module. A 110 punch tool is a special tool that will be required to

perform maintenance on the rack mounted Surge Protector CAT6. Refer to

TI 6164.( ), 1.3.7.

Figure 4-20, Rack Mount 24-Port Surge Protector CAT6

______________________________________________________________

Surge Protector Each NCC Cabinet contains at least one PCH-24-C5 LAN Surge Protector

Panel mounted in the rear of the cabinet. The PCH-24-C5 is a 24-port

interface surge protector panel, which is a 110 IDC-to-RJ45 patch panel with

built-in interface surge protection. The PCH-24-C5 is a self-resetting,

1500W, bi-directional circuit with a clamping voltage of 12 volts. Over-

voltages are safely shunted to ground using a #10 wire connected to the

cabinet ground bar.

The PCH-24-C5 panel is comprised of a face panel and 12 interface

modules. Each module provides two 110 punch-down to Ethernet

connections. The cabinet side of each surge protector module consists of two

RJ-45 connectors. A CAT6 patch cable is routed from this jack to the front

of the Ethernet Switch.

Panel Wiring

The rear of each surge protector module consists of two 110 punch-down

blocks directly opposite the corresponding RJ-45 jack.

Each block is color coded to correspond to a twisted pair. Looking at the 110

block below, the solid colored wire is connected to the left of the

corresponding colored mark and the white-striped wire is connected on the

right side.

Figure 4-21, 110 Block Wiring

Typically, CAT6 cable is punched down to the 110 block and routed to a

local workstation. The workstation end is completed with an RJ-45 plug for

connection to the workstation surge protector. Only a LAN with a hardwired

(direct connect) CAT6 connection will be routed through the surge protector

strips.

Power Strips Lesson 4

Cabinet Hardware

Description Two NIDS cabinet power strips receive power from the Automatic Transfer

Switch. All NCC equipment receives power from the two power strips.

The power strips fielded in the NIDS NCCs are the Tripp Lite PDU1215.

Figure 4-22, Cabinet Power Strip

Each power strip provides thirteen 120V outlets protected by a 15A circuit

breaker that is resettable by pressing the Reset button. The outlets are

accessible from the inside of the cabinet. There is a single convenience

outlet provided at the rear of the cabinet. Both power strips receive their

power from the ATS.

NOTE: Power strips and the KVM are the only devices plugged into the

ATS.

The redundant and primary power buses are only related to the UPS’s 1 and

2. The ATS combines this into a single power bus from the primary; if the

primary power dies the ATS switches to the redundant power source. If that

dies the ATS loses power completely. The only devices directly connected to

the primary and redundant power sources are the UPS’s.

Each power strip is grounded to the cabinet’s copper ground bar.

Interface Splitter Panel (IFSP) Lesson 4

Cabinet Hardware

Description The IFSP is only at locations where the interfaces connect to two Serial

Terminal Servers in an NCC. The IFSP will be used as the interface

demarcation point into NIDS. The IFSP provides for splitting the incoming

data signals into two data feeds as well as providing serial surge suppression.

The IFSP is always rack mounted in the back of the NCC.

This unit is mounted on the rear of the NCC Rack and is used to connect the

external weather systems (Interfaces) to the NIDS redundant servers. It

consists of a Power Distribution Unit (401020), which houses and supplies

power to the Interface cards: Serial Splitter (102010), RJ11 Splitter (410000)

and BNC Splitter (107010). The Interface cards support RS232/RS485

serial, RJ11analog and BNC analog (IRIG-B) signals, respectively. External

weather system interfaces connect to the splitter cards using DB9, BNC, and

Registered Jack 11 (RJ11) connectors as appropriate.

The Serial Splitter card has two RJ45 ports which are connected to the

primary and secondary Serial Terminal Servers using CAT6 cables. The

RJ11 Splitter card receives the DASI (DASI signal is split), Wind Measuring

Equipment (WME) or modem analog signal and outputs it to the respective

device mounted inside the NCC rack at which point it is converted to an

RS232 signal and carried via serial cables to the STSs. The BNC Splitter

card receives the IRIG-B signal from the GPS device and sends it to the

Time Server mounted inside the NCC rack and if necessary, splits the signal

and forwards it to another Time Server.

______________________________________________________________

IFSP – Power

Distribution Unit

Remove and

Replace

The Power Distribution Unit is base component of the IFSP. The Power

Distribution Unit is a rack mount card cage that can hold up to twelve cards.

The card cage has an internal backplane that delivers 12 VDC power from

two separate power supplies to each card slot in the cage.

Serial Terminal Server Lesson 4

Cabinet Hardware

Description In the NCC the STS units are installed in pairs in a NCC rack to facilitate the

Primary Host / Secondary Host automatic failover protection for weather

systems interfaces. The STS is also used at locations that do not have an

NCC as a method of providing a standardized approach for bringing external

data interfaces into NIDS. The STS is always used with either an IFP or

IFSP. External data is never directly connected to the STS without going

through a NIDS demarcation panel with surge suppression.

Serial Terminal Servers are mounted inside the hinged rear door of the NCC,

providing easy access to these components and connections. They are rack

mounted and accessible for interface connections. Serial Terminal Servers

are not limited to the NCC. They can also be used with workstations.

A Serial Terminal Server has no serviceable parts and is a LRU in the event

of failure. No specialized skills are required for the physical replacement of

the equipment.

Serial Terminal Servers will be covered in greater detail in Lesson 6,

Network Devices.

Rack Front Filter Lesson 4

Cabinet Hardware

Preventive

Maintenance

Racks installed in locations that don’t supply chilled air through the floor

will have rack front doors with an air filter. The filter should be removed and

cleaned with a vacuum cleaner, compressed air, or with water. When using

compressed air, carefully direct the air flow so it is not blowing directly on

the component. If water is used, dry the filter completely before replacing it

in the rack.

Racks installed in locations with EMI reduction requirements will have a

rack top EMI filter. This filter blocks radio signals but allows air to pass

through. The EMI filter may collect dust. The dust may be removed with a

vacuum cleaner, compressed air, or by brushing (with a paintbrush or similar

soft brush). When using compressed air, carefully direct the air flow so it is

not blowing directly on the component. The filter may be removed by

sliding it up out of the slots that hold it in place. Pull the top of the filter

away from the door while lifting. Replace the filter by reversing the process.
