6. Verify that the local power control for the blade server is set correctly.
See the online information for your management module or the
Management Module User's Guide or
the Management Module Command-Line Interface Reference Guide for more information.
7. Verify that the BladeCenter unit blowers are correctly installed and operational.
If these steps do not resolve the problem, it is likely a problem with the blade server. See “Power
problems” on page 188 for more information.
Solving undetermined problems
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.
v
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.
v
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:
1. Make sure that the control panel connector is correctly seated on the system board. See “System-board
connectors” on page 9 for the location of the connector.
2.
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.
3. Turn off the blade server.
4. Remove the blade server from the BladeCenter unit 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 expansion option.
v Hard disk drives.
v Memory modules. The minimum configuration requirement is 2 GB (two 1 GB DIMMs).
The following minimum configuration is required for the blade server to start:
v
System-board and chassis assembly (with two microprocessors)
v
Two 2 GB DIMMs
v
A functioning BladeCenter unit
6. Install and turn on the blade server. If the problem remains, suspect the following components in
order:
a. DIMM
b. System-board and chassis assembly
