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.
H0544ebk5.book Page 1 Tuesday, July 8, 2003 9:14 AM

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.
H0544ebk5.book Page 2 Tuesday, July 8, 2003 9:14 AM

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.
