You suspect a software
problem.
1. To determine whether the problem is caused by the software, make sure that:
• The server has the minimum memory that is needed to use the software. For
memory requirements, see the information that comes with the software.
If you have just installed an adapter or memory, the server might have a
memory-address conflict.
• The software is designed to operate on the server.
• Other software works on the server.
• The software works on another server.
2. If you received any error messages when using the software, see the information
that comes with the software for a description of the messages and suggested
solutions to the problem.
3. Contact the software vendor.

Solving power problems
Use this information to solve power problems.
Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the
power distribution buses. Usually, a short circuit will cause the power subsystem to shut down because of
an overcurrent condition. To diagnose a power problem, use the following general procedure:
Step 1.
Turn off the server and disconnect all power cords.
Step 2.
Check for loose cables in the power subsystem. Also check for short circuits, for example, if a
loose screw is causing a short circuit on a circuit board.
