Dell PowerEdge 1750 - Manual (Page 12)

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 mode change from SCSI to RAID
on channel x of the embedded RAID subsystem.
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Out-of-date firmware.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
for the location of the RAC Ethernet connector. If the
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.
Code Cause Corrective Action
1-1-2 Microprocessor register test failure Replace microprocessor 1. See " Microprocessors ." If the problem persists, replace
microprocessor 2.
1-1-3 CMOS write/read failure Replace the system board. See " System Board ."
1-1-4 BIOS checksum failure This fatal error usually requires replacement of the BIOS firmware. Reflash the BIOS firmware.
1-2-1 Programmable interval-timer failure Replace the system board. See " System Board ."
1-2-2
1-2-3 DMA initialization failure
DMA page register write/read failure Remove and reseat the memory modules. See " Memory ." If the problem persists, replace the
memory modules. If the problem persists, replace the system board. See " System Board ."
1-3-1 Main-memory refresh verification failure
1-3-2 No memory installed
1-3-3 Chip or data line failure in the first 64 KB of main
memory
1-3-4 Odd/even logic failure in the first 64 KB of main
memory
