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.

3.Remove the adapters and disconnect the cables and power cords to all internal and external devices until the server is at the minimum configuration that is required for the server to start (see “Solving undetermined problems” on page 93 for the minimum configuration).

4.Reconnect all ac power cords and turn on the server. If the server starts successfully, replace the adapters and devices one at a time until the problem is isolated.

If the server does not start from the minimum configuration, replace the components in the minimum configuration one at a time until the problem is isolated.

Solving Ethernet controller problems

The method that you use to test the Ethernet controller depends on which operating system you are using. See the operating-system documentation for information about Ethernet controllers, and see the Ethernet controller device-driver readme file.

Try the following procedures:

•Make sure that the correct device drivers, which come with the server, are installed and that they are at the latest level.

•Make sure that the Ethernet cable is installed correctly.

–The cable must be securely attached at all connections. If the cable is attached but the problem remains, try a different cable.

–If the Ethernet controller is set to operate at 100 Mbps, you must use Category 5 cabling.
