Software problems, Solving power problems

Software problems

•Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.

•See the parts listing in the Hardware Maintenance Manual to determine which components are customer replaceable units (CRUs) and which components are field replaceable units (FRUs).

•If an action step is preceded by “(Trained service technician only),” that step must be performed only by a trained service technician.

Symptom	Action

You suspect a software	1.	To determine whether the problem is caused by the software, make sure that:
problem.		• 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 receive any error messages while you use 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.

Universal Serial Bus (USB) port problems

•Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.

•See the parts listing in the Hardware Maintenance Manual to determine which components are customer replaceable units (CRUs) and which components are field replaceable units (FRUs).

•If an action step is preceded by “(Trained service technician only),” that step must be performed only by a trained service technician.

Symptom	Action

A USB device does not work.	1.	Make sure that:
		• The correct USB device driver is installed.
		• The operating system supports USB devices.
		• A standard PS/2 keyboard or mouse is not connected to the server. If it is, a
		USB keyboard or mouse will not work during the POST.
	2.	Make sure that the USB configuration optional devices are set correctly in the
		Setup Utility program.
	3.	If you are using a USB hub, disconnect the USB device from the hub and
		connect it directly to the server.

Solving 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:

1.Turn off the server and disconnect all ac power cords.

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.
