System Beep Codes

When an error that cannot be reported on the monitor occurs during a boot routine, the system may emit a series of beeps that identify the problem.



When a beep code is emitted, record it on a copy of the Diagnostics Checklist (located in "Getting Help" in the Installation and Troubleshooting Guide), and then

look it up in Table3-6. If you are unable to resolve the problem by looking up the meaning of the beep code, use the system diagnostics to identify a more

serious cause.

Warning: Detected missing RAID hardware for the

embedded RAID subsystem. Data loss will occur!

Press Y to switch mode to SCSI, press any other

key to disable both channels. Press Y to confirm

the change; press any other key to cancel.

Type of controller has changed since

previous system boot.

Back up information on the hard drives before changing

the type of controller used with the drives.

Warning! Embedded SCSI- RAID error

Faulty RAID adapter, or ROMB card

firmware is either corrupted or is the

wrong version.

Reseat the ROMB card. See "ROMB Card." If the message

reappears, replace the ROMB card.

Warning! Embedded SCSI- RAID firmware is not

present!

ROMB card firmware is either corrupted or

is the wrong version.

Reseat the ROMB card. See "ROMB Card." Reboot the

system. If the message reappears, replace the ROMB

card."

Warning! Firmware is out- of-date, please

update

Out-of-date firmware.

Update the system firmware. See "Using the Dell

OpenManage Server Assistant CD" in your User's Guide for

information about updating the system firmware.

Warning! No microcode update loaded for

processor x

BIOS is not current.

Update the BIOS, but do not turn the system off before

the update. See "Using the System Setup Program."

Warning! Remote Access Controller command

failure

Command protocol failure between the

RAC and ESM3.

Reseat the RAC in its system board connector. See

"Opening the System Covers," and then see Figure5-3

for the location of the RAC Ethernet connector. If the

message reappears, replace the RAC. If the problem

persists, replace the system board. See "System Board."

Warning! Unsupported Remote Access Controller

firmware version detected

RAC firmware is corrupted or is the wrong

version.

Reseat the RAC in its system board connector. See

"Opening the System Covers," and then see Figure5-3

message reappears, replace the RAC.

Write fault

Write fault on selected drive

Faulty diskette or hard drive.

Replace the diskette. If the problem persists, replace the

diskette drive. See "Installing a Diskette Drive." If the

problem persists, replace the hard drive. See "Internal

SCSI Hard Drives."

NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system will not issue beep codes related to these peripherals.
