Note: If you cannot find the problem in the troubleshooting charts, go to “Running
diagnostic programs” on page 111 to test the server. If you have run the
diagnostic test programs or if running the tests does not reveal the problem,
have the system serviced.
Expansion enclosure
problems
Action
The SCSI expansion
enclosure used to work,
but does not work now. Verify that all of the SCSI expansion enclosure hardware and cable
connections are secure.
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.
If the SCSI expansion enclosure comes with its own test instructions, use
those instructions to test it. In addition, test the power supply.
If the problem still exists and the test programs found no problem, have
the server and SCSI expansion enclosure serviced.
Software problems Action
Suspected software
problem. To determine if problems are caused by the software, verify that:
1. Your server has the minimum memory requirements needed to use
the software. For memory requirements, refer to the information that
comes with the software.
Note: If you have just installed an adapter or memory, you might
have a memory address conflict.
2. The software is designed to operate on your server.
3. Other software works on your server.
4. The software that you are using works on another system.
If you received any error messages when using the software program,
refer to the information that comes with the software for a description of
the messages and solutions to the problem.
If the problem still exists, contact your place of purchase.
Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems that might occur with
the 10/100 Mbps Ethernet controller.
Network connection problems
If the Ethernet controller cannot connect to the network, check the following:
Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is
attached but the problem persists, try a different cable.
If you set the Ethernet controller to operate at 100 Mbps, you must use
Category 5 cabling.
If you directly connect two workstations (without a hub), or if you are not using
a hub with X ports, use a crossover cable.
