d. To view NAS Gateway 300 configuration information (such as system
configuration, memory contents, interrupt request (IRQ) use, direct memory
access (DMA) use, device drivers, and so on), select
Hardware Info from
the top of the screen.
e. You cannot use the Base System Diagnostics program to test adapters; use
the procedure outlined in “Running adapter diagnostics” on page 103.
When the tests have completed, view the Test Log by selecting Utility from the top
of the screen.
If the hardware checks out OK but the problem persists during normal NAS
Gateway 300 operations, a software error might be the cause.
Viewing the test log
The test log will contain no information until the diagnostic tests have completed.
Note: If you already are running the diagnostic programs, begin with step 4.
To view the test log:
1. Ensure that a monitor, keyboard, and mouse are connected to each NAS
Gateway 300.
2. Power on the NAS Gateway 300 and watch the screen.
If the NAS Gateway 300 is on, shut down your operating system and restart the
NAS Gateway 300.
3. When the message F2 for Diagnostics appears, press F2 .
If a power-on password or administrator password is set, the NAS Gateway 300
prompts you for it. Type in the appropriate password; then, press
Enter .
4. When the Diagnostic Programs screen appears, select Utility from the top of
the screen.
5. Select View Test Log from the list that appears; then, follow the instructions on
the screen.
The system maintains the test-log data while the NAS Gateway 300 is powered
on. When you power off the power to the NAS Gateway 300, the test log is
cleared.
You can also view the test log using the Remote Supervisor Adapter interface. See
the
IBM Remote Supervisor Adapter User’s Guide provided on the Documentation
CD-ROM.
Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems that might occur with
the Ethernet controller.
Network connection problems
If the Ethernet controller cannot connect to the network:
v Ensure that the NAS Gateway 300 is correctly connected to the Ethernet with a
verified cable that has been built to the related Category 3, 4, or 5 unshielded
twisted pair (UTP) standards.
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 or better cabling.
