PCI C An error occurred on PCI bus C. Either an
adapter in PCI slot 4 or 5 or the system board
caused the error.
VRM One of the VRMs on the system board has
failed.
DASD SCSI hot-swap failure or one or more hot swap
hard drives has been removed.
SP System management error detected.

Recovering BIOS code

If the BIOS code has become damaged, such as from a power failure during a flash
update, you can recover the BIOS code using the boot block jumper and a BIOS flash
diskette.
Note: You can obtain a BIOS flash diskette from one of the following sources:
The flash memory of your server contains a protected area that cannot be overwritten.
The recovery boot block is a section of code in this protected area that enables the
server to start up and to read a flash diskette. The flash utility recovers the system
BIOS code from the BIOS recovery files on the diskette.

IBM xSeries 342: User's Reference
Cause
• Use the ServerGuide program to make a BIOS flash diskette.
• Download a BIOS flash diskette from the World Wide Web. Go to
http://www.ibm/pc/support, click IBM Server Support, and make the
selections for your server.
• Contact your IBM service representative.
Action
1. Check the error log for additional information. If
the error log indicates a problem with the
integrated Ethernet controller or the integrated
SCSI controller, have your system serviced.
2. If you cannot isolate the failing adapter from the
information in the error log, try to determine the
failing adapter by removing one adapter at a time
from PCI bus C (PCI slots 4 and 5) and restarting
the server after each adapter is removed.
If the problem persists, have the system serviced.
Check the VRM failure LEDs on the system board. If
either of the VRM failure LEDs are on:
1. Turn off the server, reseat the respective VRM,
and restart the server.
2. If the problem persists, replace the VRM. If the
problem still persists, have the system serviced.
1. Re-install the hard drives to their original location.
2. If an amber LED on a hot-swap hard disk drive is
on, replace the hard disk drive.
3. Run the diagnostics programs. Replace any
identified failing device.
4. If the error log indicates a temperature problem
and the fans are working correctly, reseat the
cable connected to DASD I2C connector (J9).
If the problem persists, have the system serviced.
Flash the system management monitor subsystem
code again. Turn off the server and disconnect ac
power cord. Wait at least 10 seconds before
reconnecting the ac power cord, and restart the
server. If problem persists, have the system serviced.
