When you are diagnosing a problem in the PS703 or PS704 blade
server, you must determine whether the problem is in the blade server
or in the BladeCenter® unit.
- If all of the blade servers have the same symptom, it is probably
a BladeCenter unit problem;
for more information, See the online information or the Hardware
Maintenance Manual and Troubleshooting Guide or Problem Determination
and Service Guide for your BladeCenter unit.
- If the BladeCenter unit
contains more than one blade server and only one of the blade servers
has the problem, troubleshoot the blade server that has the problem.
Check the LEDs on all the power supplies of the BladeCenter unit where the blade server
is installed. If the LEDs indicate that the power supplies are working
correctly, and reseating the blade server does not correct the problem,
complete the following steps:
- Make sure that the control panel connector is correctly
seated on the system board. See System-board connectors for
the location of the connector.
- If no LEDs on the control panel are working, replace the
bezel assembly; then, try to power-on the blade server from the BladeCenter Web interface.
See the online information or the BladeCenter Management Module User's
Guide for more information.
- Turn off the blade server.
- Remove the blade server from the BladeCenter unit and remove the cover.
- 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.
- I/O expansion option.
- Hard disk drives.
- Memory modules. The minimum configuration requirement is 8 GB
(two 4 GB DIMMs).
The following minimum configuration is required for the blade
server to start:
- System-board and chassis assembly (with two microprocessors)
- Two 4 GB DIMMs
- A functioning BladeCenter unit
- Install and turn on the blade server. If the problem remains,
suspect the following components in order:
- DIMM
- System-board and chassis assembly
If the problem is solved when you remove an I/O expansion
option from the blade server but the problem recurs when you reinstall
the same expansion option, suspect the expansion option; if the problem
recurs when you replace the expansion option with a different one,
suspect the System-board and chassis assembly.
If you suspect
a networking problem and the blade server passes all the system tests,
suspect a network cabling problem that is external to the system.
