Messages and Error Codes

The Dell PowerEdge 8450 Systems Service Manual contains a complete system

message and error codes listing (including beep codes). The information in the

Service Manual supersedes similar information found in the Installation and

Troubleshooting Guide.

1-2 Information Update

Fault-Resilient Booting

Fault-resilient booting is a system feature that provides an alert error message during

the system’s power-on self-test (POST) if an error is detected. If an error condition

occurs, the system stops booting, and provides the option to resume booting or to

enter setup. The following is an example of an alert error message:

Error

XXXX BIOS does not support the current stepping for Left

Processor X

Press <F1> to resume, <F2> to setup

See your system’s Installation and Troubleshooting Guide or contact Dell technical

support before pressing <F1> or <F2>.

WakeUp On LAN

WakeUp On LAN is enabled only when the system is turned on for the first

time either locally using the front panel power switch or remotely via the

Dell OpenManage™ Remote Assistant Card version 2 (DRAC 2) server management

adapter. If the system is later powered down, WakeUp On LAN remains active as

long as AC power is applied to the system.

When the system is off (powered down) and AC power is lost or the power cord is

removed, WakeUp On LAN is disabled. When AC power is restored, the system must

be manually turned on using the front panel switch (or remotely, with the DRAC 2, if

installed) to activate WakeUp On LAN.

If AC power is lost when the system is powered on and running, when AC power is

restored, the computer completely powers up and self-boots, and WakeUp On LAN is

automatically reactivated.

PCI Expansion Cards

When installing expansion cards with the Emergency Management Port (EMP)

remote console feature enabled (by pressing <F2> during the boot process to enter

the BIOS setup), option ROM space is restricted to 64 kilobytes (KB). If the remote

console feature is disabled, 80 KB of option ROM space may be used. EMP is not

presently supported on the PowerEdge 8450 system. Multiple PERC2 cards are sup-

ported in the PowerEdge 8450 system. However, the EMP remote console feature

must be disabled when any PERC2 card is present.

support.dell.com Information Update 1-3

Rack Installation Document

A Dell PowerEdge 8450 Systems Rack Installation Guide is provided with each

PowerEdge 8450 rack kit. Use this document to install the system into a rack cabinet.

This guide supersedes instructions contained in the Installation and Troubleshooting

Guide.

Jumpers, Switches, and Connectors

This section updates jumpers, switches, and connectors information found in the

Installation and Troubleshooting Guide.

•There are two additional entries for the table titled “I/O Board Connectors and

Sockets”:

PHP — PCI hot-pluggable slot indicator LEDs

IDE — CD-ROM drive connector (via the SCSI backplane board)

•The system configuration switch on the I/O board is either a red switch block

labeled “Open” or a blue switch block labeled “On.” Table 1-1 shows the possi-

ble settings for these switches. In the Settings column, Open/Off means Open

or Off, and Closed/On means Closed or On, depending on the switch block that

is installed in your system.

the switch to Closed/On before restoring

the configuration information.)

1-4 Information Update

Integrated SCSI Controller

The vendor of the integrated SCSI controller device on the I/O board is identified as

Symbios or LSI. Because LSI purchased Symbios, both vendor names are correct and

synonymous.

Multiple PERC2 Cards and Dell Diagnostics

When two or more PERC2 cards are installed in the PowerEdge 8450 system, only up

to two may be viewed or tested at any given time. The following steps are required to

view and test the selected PERC2 cards with the Dell Diagnostics:

1. During the boot process, press <F2> to enter the BIOS Setup menu.

2. Select Advanced.

3. Select PCI Configuration.

A list of PCI slots is displayed, starting with PCI Embedded SCSI, PCI Slot 1,

PCI Slot 2, and so on.

4. Select the PCI slots (maximum of two) containing the PERC2 cards that are to be

viewed.

Ensure that the Option ROM Scan selection for these cards is set to Enabled

(the default).

Make a note of the two PCI slot numbers that the PERC2 cards occupy. Later,

Dell Diagnostics will refer to the controllers as card 0 and card 1, with card 0

assigned the lowest-numbered PCI slot.

For example, if the PERC2 cards being viewed are installed in PCI slots 2 and 4,

Dell Diagnostics displays information for card 0 (the PERC2 card in PCI slot 2)

and for card 1 (the PERC2 card in PCI slot 4).

5. Set the Option ROM Scan for all other PCI slots to Disabled. Also, from the list,

disable the PCI Embedded SCSI controller.

6. Press <F10> to save these settings and exit the BIOS setup utility. Upon exiting,

the system will reboot.

7. Run the Dell Diagnostics to obtain information and perform testing on the PERC2

cards selected in step 4.

8. Upon completion of testing, if additional PERC2 adapter cards are installed, those

cards may be viewed and tested by rebooting and performing steps 1 through 7.

Microprocessor Replacement

Microprocessor latches are intended to provide removal and initial insertion assistance.

To complete the removal of a microprocessor, initially use the latch to partially

remove a microprocessor from its socket. Then grasp the microprocessor and heat

sink assembly with both hands and lift it up and out of its socket and guide bracket.

To complete the insertion of a microprocessor, firmly press the microprocessor into

its socket until it is completely seated and the latch closes freely.

Microprocessor Speed

The Dell PowerEdge 8450 Systems User’s Guide states that the system supports

microprocessors with an internal operating frequency of 500 MHz. However, it should

be noted that microprocessors with internal operating frequencies of 800 MHz or

higher are supported.

Setting Microprocessor Speed Jumpers

When changing or upgrading microprocessors, you must verify that the microproces-

sor speed jumper settings are correctly configured for the new microprocessors.

See the system information label and Appendix A of your system’s Installation and

Troubleshooting Guide for a list of processor speeds and the corresponding jumper

settings. For microprocessors operating at internal speeds faster than those listed,

use the speed jumper setting for the fastest microprocessor listed.

Operating System Clock Setting and

System Event Log

If the system clock setting within the operating system is changed or updated, you

should reboot the system if you require accurate time-stamping of system log events.

Otherwise, any system events that are logged after the time change will be time-

stamped with respect to the original time setting. Event log time stamps will not be

referenced to the new time setting until the system is rebooted.

There are no other issues associated with changing the system time; if the accurate

time-reporting of system events is not a concern, rebooting is not required.

1-6 Information Update

Diskette-Based Diagnostics

You can run the Dell Diagnostics from a hard-disk drive utility partition or from dis-

kettes. When using diskette-based diagnostics, observe the following precautions:

•Ensure that the Dell Diagnostics diskette number 4 is not write protected.

•Ensure that the Dell Diagnostics diskette number 4 remains in the drive

throughout the duration of the diagnostics testing.

Failure to take these precautions will cause the diagnostics to fail.

BIOS Version Requirements

Systems with the newer versions of the Intel®Pentium®III microprocessors

(700 MHz, 750 MHz, 800 MHz, or higher speeds) require a system setup program

BIOS A03 or a later version. If you download and flash an A01 or an A02 BIOS, your

system may not operate. To recover a system BIOS, see “Recovering the BIOS”in

your Dell PowerEdge 8450 Systems User’s Guide.

Réveil sur LAN

La fonction WakeUp On LAN (réveil sur réseau local) est activée uniquement lorsque

le système est allumépour la première fois, soit localement àl'aide du commutateur

d'alimentation du panneau avant, soit àdistance par l'intermédiaire de la carte de ges-

tion de serveur DRAC 2 (Dell OpenManage™Remote Assistant Card version 2 [carte

assistant àdistance Dell OpenManage™version 2]). Si le système est mis hors ten-

sion par après, la fonction de réveil sur réseau local reste active tant que le système

continue d'être alimentéen CA.

Lorsque le système est éteint (mis hors tension) et qu'il y a une coupure de l'alimen-

tation en CA ou que le cordon d'alimentation est débranché, la fonction de réveil sur

réseau local est désactivée. Une fois l'alimentation en CA rétablie, le système doit

être allumémanuellement àl'aide du commutateur du panneau avant (ou àdistance,

àl'aide de la carte DRAC 2, si elle est installée) pour activer la fonction de réveil sur

réseau local.

Si une coupure de l'alimentation en CA a lieu alors que le système est alluméet en

cours de fonctionnement, lorsque l'alimentation en CA est rétablie, l'ordinateur

s'allume et démarre complètement de lui-même et la fonction de réveil sur réseau

local est automatiquement réactivée.
