Information Update 1-1

This document provides updated information for your system on the following topics:

• Processor

• Flashing the system BIOS

• Installing the Red Hat®Linux Advanced Server 2.1 operating system

• COM2 availability

• Teamed NIC addresses with the Novell®NetWare®6.0 operating system

• Installing a processor

• Installing or removing a ROMB backup battery

• Connecting external SCSI devices

• System message update

Processor

Your system contains up to two Intel®Xeon™ processors with a front-side bus speed of

either 400 or 533 MHz, and a minimum internal operating frequency of 2.4 GHz.

In systems with a 400-MHz front-side bus, the 266-MHz DDR SDRAM memory modules

run at 200 MHz.

Flashing the System BIOS

If you need to flash the system’s BIOS, go to the Dell Support website at support.dell.com

and download the most current BIOS available for your system. Do not use the system

BIOS that was provided on your Dell OpenManage Server Assistant CD.

Installing Red Hat Linux Advanced Server 2.1

Dell recommends installing Red Hat Linux Advanced Server 2.1 using the Server Assistant

CD, which ensures proper loading of all the drivers and avoids use of the driver update

diskette. If you intend to install Red Hat Linux using the driver update diskette instead of

the Server Assistant CD, ensure that you download the latest drivers for Red Hat Linux

Advanced Server 2.1 from the Dell Support website at support.dell.com.

1-2 Information Update

www.dell.com | support.dell.com

The updated drivers on the Dell Support website include the latest script file, which

prevents future erroneous error messages by ensuring that the drivers for the embedded

SCSI controller are placed in the correct location.

Run the script file after installing the operating system. See the readme file included with

the updated drivers for more information about running the script file.

COM2 Availability

COM2 circuitry exists on the system board, but it is reserved for use by an optional ERA/O

controller. Although COM2 may be reported as available under certain operating systems,

COM1 is the only serial port that is available on your system.

Teamed NIC Addresses With Novell

NetWare 6.0

When two or more Gigabit Ethernet Channel or 802.3ad NICs are set up as a team when

running the Novell NetWare 6.0 operating system, the team is assigned a single media

access control (MAC) address that identifies the team to the network. The Broadcom

Advanced Server program driver that is used to form the team displays the MAC address as

FFFFFFFFFFFF rather than displaying the correct address of the team.

This issue does not affect the functionality of the team, since the team address is available

to the network.

Installing a Processor

Always use the new heat sink that ships with a processor upgrade kit. Thermal interface

grease on the underside of the heat sink is critical to maintaining optimum contact between

the heat sink and the processor. Used or older heat sinks may not have enough grease

remaining on it to ensure proper contact.

Installing or Removing a ROMB Backup

Battery

If an ERA/O controller is installed under the ROMB backup battery, remove the SCSI

backplane board before removing or installing the battery, and replace the SCSI backplane

board after removing or installing the battery.

Information Update 1-3

CAUTION: Before you perform this procedure you must turn off the system and

disconnect it from its power source. See your System Information Guide for

complete information about safety precautions, working inside the computer,

and protecting against electrostatic discharge.

NOTE: The following two procedures assume that you have already removed the

system covers and performed the initial steps of "Installing a ROMB Card" or

"Removing a ROMB Card" in your Installation and Troubleshooting Guide.

Removing the SCSI Backplane Board

1Pull each hard-drive carrier partially out of its slot, approximately 2.5 cm (1 inch).

2Disconnect the diskette-drive interface cable from the FLOPPY connector on the

backplane board. See Figure 1-1.

3Disconnect the CD drive interface cable from the CD_ROM connector on the

backplane board. See Figure 1-1.

4Press the release latch in toward the backplane board and use the handle to pull the

board out of its connector and up out of the chassis. See Figure 1-1.

Installing the SCSI Backplane Board

1Insert the SCSI backplane board into the chassis:

aFit the metal tabs (one tab at each end of the backplane) into the slots in the

chassis wall and lower the backplane into the chassis, ensuring that the CD and

diskette drive interface cables are not caught under the backplane. See Figure 1-1.

bPress down firmly over the handle to seat the backplane in its connector.

2Pivot the release latch out into the securing slot in the chassis.

3Connect the CD drive interface cable to the CD_ROM connector on the backplane

board.

4Connect the diskette-drive interface cable to the FLOPPY connector on the backplane

board.

5Press all installed hard drives firmly back into the SCSI connectors on the backplane.
