The WAAS software does not support the use of a keyboard or mouse
(Personal System/2 [PS/2] or Universal Serial Bus [USB]) for Linux and WAAS
software troubleshooting. However, the keyboard and mouse are supported by the
BIOS for power-on self-test (POST) and the diagnostic programs that are located
in the device ROM.
When console redirection is enabled, all the tests available from a keyboard are
accessible through the console connection as well. (Mouse support, however, is
not available through the console connection.)
You can run all the diagnostics and tests that are supported by the BIOS, with a
few exceptions. Tests for ports (such as the systems-management Ethernet
connector and the SAS connector) that are not supported by the WAAS software
are invalid.
To identify system problems, follow these steps:
Check the front panel LED indicators. (See
Power down the device and all external devices.
Check all cables and power cords. (See the
section on page 5-3.)
Power up all external devices.
