Expansion enclosure
problems
Verify that:
1. The cables for all external SCSI options are connected correctly.
2. The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
3. Any external SCSI option is turned on. You must turn on an external SCSI option
before turning on the server.
For more information, see your SCSI and expansion enclosure documentation.
The SCSI expansion enclosure
used to work, but does not
work now.
General problems Call for service.
Problems such as broken cover
locks or indicator lights not
working.
Intermittent problems Verify that:
1. All cables and cords are connected securely to the rear of the server and attached
options.
2. When the server is turned on, air is flowing from the rear of the server at the fan
grill. If there is no air flow, the fan is not working. This causes the server to
overheat and shut down.
3. Ensure that the SCSI bus and devices are configured correctly and that the last
external device in each SCSI chain is terminated correctly.
If the items above are correct, call for service.
A problem occurs only
occasionally and is difficult to
detect.
Keyboard, mouse, or pointing-
device problems
1. Make sure that the keyboard cable is properly connected to the server.
2. Make sure that the server and the monitor are turned on.
3. Try using another keyboard.
If the items above are correct, call for service.
All or some keys on the
keyboard do not work.
The mouse or pointing device
does not work. 1. Verify that the mouse or pointing-device cable is securely connected and the
device drivers are installed correctly.
2. Try using another mouse or pointing device.
If the problem remains, call for service.
