IBM HS40 - BladeCenter - 8839, Руководство по техническому обслуживанию и устранению неисправностей

Страница: 112 / 172

Notes:
1. Damaged data in CMOS can cause undetermined problems. To reset the
CMOS, remove the battery for 15 minutes, and then reinstall the battery.
2. Damaged data in BIOS code can cause undetermined problems.
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).
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
turn on the blade server from the BladeCenter web interface (see the
BladeCenter documentation for more information).
3. Turn off the blade server.
4. Remove the blade server and remove the cover.
5. Remove or disconnect the following devices (one at a time) until you find 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
6. Install and turn on the blade server. If the problem remains, suspect the
following FRUs in the order listed:
v
DIMM
v
System board
v
Microprocessor
Notes:
1. If the problem is solved when you remove an I/O adapter from the blade server
and replacing that I/O adapter does not correct the problem, suspect the system
board.
2. If you suspect a networking problem and the blade server passes all the system
tests, suspect a network cabling problem external to the blade server.
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.
v
Machine type and model
v
Microprocessor or hard disk upgrades
v
Failure symptom:
– Does the server fail the diagnostics tests?
– What, when, where, single, or multiple servers?
– Is the failure repeatable?
– Has this configuration ever worked?
