5. If you just installed an optional device, remove it, and restart the server. If
the server now starts, you might have installed more devices than the power
supply supports.
6. See power button/LED “Front view” on page 21.
7. See “Solving undetermined problems” on page 60.
The server does not turn off. 1. Determine whether you are using an Advanced Configuration and Power
Interface (ACPI) or a non-ACPI operating system. If you are using a non-ACPI
operating system, complete the following steps:
a. Press Ctrl+Alt+Delete.
b. Turn off the server by pressing the power-control button for 5 seconds.
c. Restart the server.
d. If the server fails POST and the power-control button does not work,
disconnect the power cord for 5 seconds; then, reconnect the power cord
and restart the server.
2. If the problem remains or if you are using an ACPI-aware operating system,
suspect the system board.
The server unexpectedly shuts
down, and the LEDs on the
operator information panel are
not lit. See “Solving undetermined problems” on page 60.

Table 14. Software problems and actions
Symptom Action
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.
