1. Damaged data in CMOS can cause undetermined problems. To reset the
2. Damaged data in BIOS code can cause undetermined problems.
Check the LEDs on all the power supplies of the BladeCenter unit where the blade
server is installed. If the LEDs indicate the power supplies are working correctly,
and reseating the blade server does not correct the problem, complete the following
steps:
1. Check that the front panel is connected to the system board.
2. If no LEDs on the front panel are working, replace the front panel; then, try to
3. Turn off the blade server.
4. Remove the blade server and remove the cover.

Problem determination tips

Because of the variety of hardware and software combinations that can be
encountered, use the following information to assist you in problem determination. If
possible, have this information available when requesting assistance from Service
Support and Engineering functions.

CMOS, remove the battery for 15 minutes, and then reinstall the battery.
v Flash the system with the latest BIOS code.
v If the system appears inoperative, recover the BIOS (see "Recovering the
BIOS code" on page 30).
turn on the blade server from the BladeCenter web interface (see the

failure (reinstall, turn on and reconfigure the blade server each time):
v I/O adapter
v Drives
v Memory modules (minimum requirement = two 256 MB DIMMs)
The following components are required, at a minimum, for the blade server to
operate:
v System board
v One microprocessor
v Memory (with a minimum of two 256 MB DIMMs)
v A functioning BladeCenter
following FRUs in the order listed:
v DIMM
v System board
v Microprocessor
and replacing that I/O adapter does not correct the problem, suspect the system
board.
tests, suspect a network cabling problem external to the blade server.
– Does the server fail the diagnostics tests?
– What, when, where, single, or multiple servers?
– Is the failure repeatable?
– Has this configuration ever worked?
