Chapter 2 - Installation

Unpacking the Density System

1. Inspect the shipping box for damage.

2. Remove the Density Series system from the shipping container, and place on a secure working surface.

Installation of a Density System into a Cabinet

The Density Series system is a rack-mount enclosure designed to be installed in aCubix System 1010 cabinet or other RETMA-compatible 19" wide equipment rack.

1. Remove the middle and rear sliding rails from the sides of the Density System.

2. With the middle rails still inserted into the rear rails, mount them into the cabinet using the four brackets provided.

VKM (Video, Keyboard and Mouse)-External Cabling

These devices may be shared between multiple systems. This is accomplished bydaisy-chaining the systems together with DB-25 male to male cables attached to theVKM connectors which are located on the back of the Mux/IES board (see Figure 8). Amaximum number of eight Density chassis may be VKM connected.

6

WARNING!Care should be taken when installing a Density Series system. Theweight of a fully loaded Density Series enclosure (approx. 130 lbs.)placed on fully extended rails may cause the cabinet to tip forward.The cabinet should be secured before installing the enclosure.

Connect the unused VKM connector onthe first system to the Video/Keyboard/Mouse Breakout Module, using DB-25cabling. (VKM Module can be mounted inthe top of the System 1010 cabinet orwherever it is convenient.)

If the monitor, keyboard, and mouse arenot already connected to the breakoutmodule, route the cables for these devicesinto the cabinet via the access hole in thetop cover and connect the cables to thebreakout module.

Connect the video terminator plug to theunused VKM connectors on the last system.

Mux Option Switch (S1)

Mux options determine the behavior of the Density system when the console is locked.The options are set with an 8 position DIP switch (S1) on the Multiplexor/ IES board(see Figure 4 for the switch location). Changing the following Mux option switches must be followed by a power-on sequence of the Density chassis. Positions 1 through 4 are Mux option selections. Positions 5 through 8 should not change, but remain consistent with Table 3, factory default settings.

Video Only - If this option is enabled and the console is locked, all of themuxed devices except for the monitor are disabled. The monitor remains functional on the channel that was selected at the time the lock occurred.

This is a useful feature if there is a management application running on one of the computers in the system. By selecting the processor group containingthis computer before locking the console, the screen on the managementapplication can be monitored. However, the other muxed devices and the console functions remain disabled, thus eliminating the possibility of unauthorized intervention.

Table 2 Mux Option Switch Definitions (S1) (cont.)

Option

Monitor/Keyboard/Mouse/Reset - If this option is enabled and the consoleis locked, the only muxed device that will be disabled is the floppy diskdrive. The monitor, keyboard, and mouse will continue to function on theselected channel.

In addition, the "Reset Selected Group" pushbutton on the front panel of thesystem will remain functional, allowing an operator to reset the computerselected as the current group at the time the console is locked.

The "Group Select" pushbuttons are disabled, thus preventing the operatorfrom resetting another processor group.

This is a useful feature if the system administrator wants to prevent use ofthe floppy drive for security purposes.

Floppy Channel 1 - If this option is enabled and either the console islocked or the system is disabled, the floppy drive will be connected to thefirst mux channel, regardless of the processor group currently selected.

Master Console Key lock - Systems may be connected by daisy-chainingthem via the VKM connectors on the rear panel of the Multiplexor/IESboard. This connection is required to share a m o n i t o r, keyboard, and mousebetween as many as eight systems.

If the Master Console Key lock option is enabled, the system will functionas a "master console." If the master console is locked, the consoles of all systems connected to the master console are locked, regardless of theposition of the key switch on their front panels.

A Density Series system will not function as a master console if the systemis turned off.

A Density Series system with the Master Console Key lock option enabledwill remain the master console through a power failure.

More than one system in a daisy-chain can have the Master Console Keylock option enabled. If this is the case, it is necessary to unlock the keyswitch on the front panel of each system with the option enabled. As longas the key switch remains in the locked position on any system with themaster key lock option enabled, all of the systems in the daisy-chain willremain locked.

Integrating Density Series into a GlobalVision Management System

The Density Series system may be managed by an existing GlobalVision (version 2.15or greater) management system operating in a Cubix ERS/FT II or PowerSMP serieschassis. The following section will provide the configuration necessary to integrate theDensity system into the existing management system.

Configuring IES Data Highway Address

The Density Series system includes an out-of-band Data Highway which connects thechassis Intelligent Environmental Sensor (IES) to a GlobalVision management processor (refer to the GlobalVision Management System User’s Guide). This datahighway can be daisy-chained between systems to allow management of up to 31enclosures from a single GlobalVision management processor.

Each chassis connected to the IES data highway must be assigned a unique data highway address. The GlobalVision console application uses this address to identifyand communicate with each IES module. Valid IES addresses range from 1 to 31. The factory default address of the IES is 1.

The Density Series IES Data Highway is integrated onto the Mux/IES board. Theaddress of the IES is determined by an 8-position DIP switch (S2) located on the topedge of the board (see Figure 4 for switch location). Each chassis that is added isassigned the next address number in the sequence. S2 must be set accordingly. Notwo chassis can have the same address.

Table 4 contains valid IES address switch configurations for 31 chassis.

on on on onNo Mux Options Enabled - The option switches override one or more of theeffects of locking the console using the console Mux. The console Mux isexplained in Chapter 3 of this manual. If none of the key lock options areenabled, locking the console disables the following functions:

● Group selection pushbuttons (this prevents the operator from changing mux channels)

● Group Power pushbuttons.● BC Reset pushbutton. ● Muxed device connections (monitor, keyboard, mouse, and floppy drive)

are disabled.

1. Connect one end of the data highway cable to either of the Out-of-Band DataHighway Connections found on the Mux/IES board (see Figure 3).

2. If this system is not the last device in the chain, connect the other Out-of-BandData Highway Connection to the next device. Set switch S3 (see Figure 4 forswitch location) to the OFF position. The switch is OFF when it is pointing to theleft when viewed from the rear of the Density Series system.

3. If this system is the last device in the chain, terminate the highway by settingswitch S3 to the ON position. The switch is ON when it is pointing to the rightwhen viewed from the rear of the Density system.

Data Highway Adapter

Density Series servers may optionally be used as the GlobalVision Console for a groupof Cubix enclosures. The server which will act as the GlobalVision Console requiresinstallation of a Data Highway Adapter to the COM2 header. This adapter provides an interface point for the GlobalVision console processor to collect IES data from all chassis in the data highway chain.

Perform the following instructions to install a data highway adapter on a Density Seriess e r v e r.

1. Remove the cover plate for IES Data Highway Adapter located in the rear of the DP Density chassis. (See Figure 3. Location may vary on other chassis.)

2. Attach the 10-pin ribbon cable of the Data Highway Adapter to the COM2 header:

● SP boards - on the top edge of the board.● DP boards - the jack is located along the top edge of the board.

NOTE!While similar to an RJ-11 telephone station cable, the datahighway cable is wired as a "straight through" cable and cannotbe replaced using a standard telephone cable. The cable will havea white sticker marked "Cubix IES Module Only."

IES Data Highway Cable

After setting the IES address, connect the Density Series system to the Cubix data highway.

1. At the front console, select and turn power off to the group location where youintend to install the server board (refer to Chapter 3 for front console operationinstructions).

2. If a hard-drive is installed in the group hard drive slot, remove the hard drive andthe SP or DP board.

3. Configure the switch and jumper settings on the board being installed. (Refer tothe Quick Reference Guide accompanying the board.)

4. Insert the board into the group slot ensuring the card interface tabs are alignedwith the center of the slot.

5. Seat the processor card into its slot by firmly pressing on the top of the card withthe palm of your hand.

6. Install the hard drive assemblyinto the appropriate hard drivebay located in the front of theDensity closure (Figure 2).The hard drive assembly will fitinto the hard drive interface ofthe I/O board. Make sure it isseated.

7. At the front console applypower to the processor group.

Figure 9 Inserting Server Board into Chassis Group Slot

13

CAUTION!Group power must be off before installing any Cubix processors,peripheral boards, or third-party peripheral cards. Failure to followthis warning may result in damage to the Density Series system and boards being installed.

3. Secure the Data Highway Adapter board in the cut out area. (The Data Highway Adapter assembly consists of one A4212 board, ribbon cable, two brackets and two screws.)

Installing Additional Server Boards (DP or SP Series)

The following instructions provide general installation instructions for Density Seriescompatible server boards. Refer to the appropriate manual supplied with the processorboard for detailed configuration instructions.

14

Installing/Replacing Power Supply

Density Series uses three hot-swappable load-sharing Power Supplies in a redundantfault-tolerant n+1 configuration. Redundant cooling systems provide added resilience.

The steps for replacing a Power Supply are quite simple. Refer to Figure 3 for locationof Power Supplies.

1. The power supply that does not have the green light on is the power supply that needs replacement.

2. Turn the switch to an “off” position on the Power Supply to be removed.3. Loosen the two captive screws and grasp the Power Supply handle. Pull the

Power Supply out of the chassis.4. Insert the replacement Power Supply.5. Secure the captive screws.6. Turn the new Power Supply “on”.

CAUTION!The Density System requires two power supplies to provide powerto server groups. Make certain there are two Power Supplyswitches “on” before removing the third Power Supply.

Status LEDs- Display Diagnostic information

Power - Green indicates that the power supplies are functioning properly. Red indicatesa failure of one of the power supplies, or power supply fans. To find the faulty powersupply, additional LEDs are located on each power supply.

Fans - Green indicates that the system fans (in the front, below the disk drives) areoperating correctly. Red indicates a system fan failure.

Temperature - Green indicates system temperature is withinacceptable operating parameters. Red indicates system temperature has exceeded acceptable operating parameters.
