Information Update 3

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

• Quad-core processor upgrades

• NIC teaming restrictions

• Monitor connections when installing an operating system

• NIC activity LED

• Throttling of server modules

• Server-module board DIP switch settings

• Console redirection information

• Microsoft

Windows

2000 Advanced Server operating system information

• System diagnostics–NIC entry in PCI device list

• Linux Enumeration of NICs

• System Setup program updates

Quad-Core Processor Upgrades

If the inside of the blade handle is labeled with a "II," your system is upgradeable, with some restrictions,

to the Quad-Core Intel®Xeon®Processor 5300 series when these processors become available. See

support.dell.com for information on processor availability and upgrade options for your system.

NIC Teaming Restrictions

Each server module (blade) in your system provides two integrated Broadcom Gb Ethernet ports as well

as support for an optional Broadcom or Intel

dual-port Gb Ethernet network adapter daughter card.

Under the Microsoft Windows operating system, your system provides network teaming support under

the following configurations:

• The two integrated Broadcom Gb Ethernet ports can be teamed using the Broadcom Advanced Server

Program (BASP) software.

• Using BASP, the two integrated Broadcom Gb Ethernet ports can be teamed with the optional

Broadcom dual-port Gb Ethernet daughter card

, for a total of up to four ports.

• Two separate teams can be created using BASP. The first team consists of the two integrated Broadcom

Gb Ethernet ports. The second team is made up of the two ports on the optional Intel Gb Ethernet

daughter card.

• The two ports on the optional Intel Gb Ethernet daughter card can be teamed using the

Intel

Advanced Network Services (iANS) software.

NOTICE: Your system does not support the concurrent presence of an Intel port-based team created with iANS

and a second Broadcom port-based team created with BASP.

4Information Update

Monitor Connections When Installing an Operating System

NOTICE: If you install an operating system on a server module and your system uses an Avocent Digital Access

KVM module, you must connect the monitor to the KVM module rather than the server module front panel.

NIC Activity LED

The NIC activity LED on the system front panel may occasionally illuminate due to baseboard

management controller (BMC) activity. This is normal behavior for your system.

Throttling of Server Modules

If a power supply or fan module is removed from the system, all server modules (blades) in the system

will be "throttled" until the power supply or fan module is replaced. Throttling reduces the power

consumption of the server modules by changing the processor duty cycle. This will reduce the blade

performance by approximately 50%. The enclosure’s System Event Log (SEL) will indicate if throttling

of the blades has occurred.

If a power supply module or fan module fails but has not been removed, one or more server modules will

be throttled depending on the system configuration. For more information, see the Dell Remote

Access/Modular Chassis User’s Guide.

Server Module Board DIP Switch

Table 1-1 lists all switch settings for the server-module DIP switch on the server module board. Note that

switches 3 though 6 are reserved, and should not be changed from their default values. See "Switches and

Connectors" in the system Installation and Troubleshooting Guide for the location of the DIP switch on

the server module board.

Table 1-1. Server-Module DIP Switch Settings

DIP Switch Setting Description

PWRD_EN

(Switch 1)

(default) The password feature is enabled when switch 1 is set to "on."

The password feature is disabled when switch 1 is set to "off."

NVRAM_CLR

(Switch 2)

(default) The configuration settings in NVRAM are retained at system

boot when switch 2 is set to "off."

The configuration settings in NVRAM are cleared at next

system boot when switch 2 is set to "on."

Switch 3 Reserved. Do not change.

Information Update 5

Console Redirection Information

The Digital Access KVM (dKVM) can be connected to only one server module at a time. If the dKVM is

switched to a different server module by using the KVM button located on a server module, or from the

On-Screen Configuration and Reporting (OSCAR) user interface of the dKVM module, the view of

other remote console redirection sessions will change to the selected server module.

Microsoft Windows 2000 Advanced Server Information

If you install the Microsoft Windows 2000 Advanced Server operating system using the Dell Server

Assistant and reboot the system, Windows Device Manager may not initially display all installed

Broadcom NIC ports. The Device Manager may also display the following error message:

This device cannot find enough free resources that it can use.

If this situation occurs, restart the system. For more information, see Microsoft Knowledge Base article

KB918417 on support.microsoft.com.

System Diagnostics

In the list of PCI devices displayed by the system diagnostics program, the system’s

integrated Broadcom

NIC ports and optional

Broadcom dual-port Ethernet daughter cards will be identified as Vendor 14E4

Product 16AC. The functionality of the ports is not affected.

Switch 4 Reserved. Do not change.

Switch 5 Reserved. Do not change.

Switch 6 Reserved. Do not change.

DIP Switch Setting Description

6Information Update

Linux Enumeration of NICs

Linux operating system versions that use the udev kernel device manager enumerate the NICs differently

than earlier Linux versions that used the devfs device manager. Although this does not affect system

functionality, when using Red Hat®Enterprise Linux (version 4) or SUSE®Linux Enterprise Server 9

operating systems, the NICs are enumerated in reverse: NIC1 is configured as eth1 rather than as eth0,

and NIC2 is configured as eth0 rather than as eth1. For further information and methods of changing

default device enumerations, see the "Network Interface Card Naming" white paper available at

linux.dell.com.

System Setup Program Updates

Following are updates to the System Setup program.

Main Screen

Figure 1-1 shows the updated main System Setup program screen. Table 1-2 describes a new option

on the System Setup main screen.

Information Update 7

Memory Screen

Table 1-3 lists a new option on the Memory Information screen.

Table 1-2. System Setup Program Main Screen Option

Option Description

Boot Sequence Retry

(Disabled default)

Enables or disables the Boot Sequence Retry feature. When set to Enabled, the

system re-attempts the boot sequence after a 30-second timeout if the previous

boot attempt failed.

Table 1-3. Memory Information Screen Options

Option Description

Low Power Mode

(Disabled default)

Enables or disables Low Power Mode. When set to Enabled, the memory runs at

reduced speed to conserve power. Disabled sets the memory to run at full speed.
