Information Update 5

Non-Optimal Memory Configurations

Memory configurations other than those listed in Table 3-1 and Table 3-2

of the Hardware Owner’s Manual are non-optimal configurations. The POST

may halt when a non-optimal memory configuration is detected and the

following message is displayed:

Non-Optimal Memory Configuration

Press F1 to continue or F2 for Setup

NOTE: Mixing DIMMs of different speeds renders the memory configuration

non-optimal. The system clocks down the performance to the slowest speed

in the DIMM set for the channel.

Regional Hardware Owner’s Manuals Available

on the Web

At production time, the translated regional versions of the Hardware Owner’s

Manual were unavailable for inclusion on the Dell OpenManage™

Documentation CD, version 5.2. All versions of the Hardware Owner’s

Manuals that are normally delivered on the CD are available for download

on the Web at support.dell.com.

Using the Online Diagnostics

The online Server Administrator Diagnostics tool mentioned in the section

"Using Server Administration Diagnostics" in the Hardware Owner’s Manual

has been replaced by the online Dell PowerEdge™Diagnostics suite of

diagnostic programs. Dell PowerEdge Diagnostics includes online diagnostic

tests for chassis and storage components such as hard drives, physical

memory, communications ports, NICs, CMOS, and more.

To assess a system problem, first use the online Dell PowerEdge Diagnostics.

If you are unable to identify the problem using the PowerEdge Diagnostics,

then use the system diagnostics.

The files required to run PowerEdge Diagnostics for systems running

supported Microsoft®Windows®and Linux operating systems are available

at support.dell.com and on the CDs that came with your system. For

information about using diagnostics, see the Dell PowerEdge Diagnostics

User's Guide.

6Information Update

System Setup Program Updates

Memory Optimizer Technology Feature

The current BIOS update provides a memory optimization feature on the

Memory Information screen of the System Setup Program. The Memory

Optimizer Technology option enables you to set the two DRAM controllers

to work independently in parallel 64-bit mode (Advanced ECC is not

available in this mode) or disable the feature to run the controllers in the

default 128-bit mode with Advanced ECC.

QDMA Mode Feature

On the Integrated Devices screen, a QDMA Mode option is now available for

the Embedded SATA field. When set to QDMA Mode, the embedded SATA

controller supports ATAPI devices at an increased data transfer rate than the

PIO rate that is supported in ATA Mode. A device driver must be installed

on your operating system to use QDMA Mode.

Demand-Based Power Management Feature

The Demand-Based Power Management option on the CPU Information

screen of the System Setup Program, which enables AMD PowerNow!™

technology features on your CPU(s), is not supported in Red Hat®Enterprise

Linux®operating systems prior to version 5.

SUSE®Linux Enterprise Server 10 fully supports demand-based power

management. SUSE Linux Enterprise Server 9 supports demand-based power

management on dual-core AMD processors, but not on the newer quad-core

processors.

Additional CPU Information

On the CPU Information screen, the processor fields now indicate the family,

model, and stepping of the specified processor.

Information Update 7

Default Settings Update

The following bullets are updates to information listed in your Hardware

Owner’s Manual.

•Onthe

Serial Communication

screen, the default setting for the

Serial

Communication

field is

On without Console Redirection

•Onthe

Serial Communication

screen, the default setting for the

Failsafe

Baud Rate

field is

115200

System Start-up Behavior

Note the following events that may occur on your system during start-up.

• On systems with large memory configurations, the video monitor can take

from several seconds to approximately two minutes to display an image

at startup.

• If you are running the Red Hat Enterprise Linux WS, ES, or AS

(Version 4) (x86-64) operating system, the system may display the

following on-screen message several times during start-up:

clear kernel mapping: mapping is split: will leak

memory

This message is specific to the operating system and does not indicate

a problem with your system hardware.

Overcurrent Events on USB Ports

Some USB devices can cause an overcurrent event on your system’s USB

ports. When this occurs, the system disables one or more of the affected USB

ports, and communication with the attached USB devices is lost. An on-

screen system message may appear noting the event, but this is not always

the case, particularly with devices connected to the rear USB ports. If an

overcurrent event disables your system’s USB ports, re-enable the ports by

restarting your system.

If overcurrent events persist, you may need to remove or replace the USB

device(s) connected to your system.

8Information Update

LCD Status Message Update

Table 1-1 lists updates to the LCD status messages that can occur and the

probable cause for each message. The LCD messages refer to events recorded

in the system event log (SEL). For information on the SEL and configuring

systems management settings, see your systems management software

documentation.

Table 1-1. LCD Status Messages

If AC power was lost, this message

is information only. If the power

The existing CPU

pairing in the system is

not supported.

Change the CPUs to a matched

pair or other valid configuration.

Information Update 9

System Board Jumpers

The jumper settings shown in Figure 6-1 and described in Table 6-1 of your

system’s Hardware Owner’s Manual are incorrect. The correct settings are

shown in Figure 1-1 and described in Table 1-2.

Figure 1-1. System Board Jumpers

10 Information Update

Creating a BMC User Password

You must assign a valid LAN user name and password before you can connect

to your system's Baseboard Management Controller (BMC) using the BMC

Management Utility. There are two methods of creating a LAN user name

and password:

• If you access the BMC Remote Access Utility by pressing <CTRL+E>

during system startup, you can create a LAN user name, and a password

with up to 16 characters. (Note that only one LAN user name and

associated password can be created using this utility.) For information

on this option, see "Baseboard Management Controller Configuration" in

your

Dell OpenManage Baseboard Management Controller Utilities User’s

Guide

• If you use the Deployment Toolkit SYSCFG.EXE utility, you can create a

LAN user name, and a password of up to 20 characters using the

syscfg

passwordaction

command. For more information, see "Configuring

New BMC Users" in the BMC

User’s Guide

Table 1-2. System Board Jumper Settings

Jumper Setting Description

NVRAM_CLR (default) The configuration settings are retained

at system boot.

The configuration settings are cleared at

the next system boot. (If the configuration

settings become corrupted to the point where

the system will not boot, install the jumper

and boot the system. Remove the jumper

before restoring the configuration

information.)

PWRD_EN (default) The password feature is enabled.

The password feature is disabled.
