The A5159B adapter is a single field-replaceable unit (FRU)
and does not contain any field-serviceable parts. Troubleshooting
procedures described in this section are limited to verifying that
the adapter is operational and a valid connection is established. In general, follow these steps to troubleshoot the A5159B
adapter: Check the connection. Make sure that the correct cable is used, connected,
and operating properly and that there are no bent pins in any of
the connectors. Check SCSI bus compatibility. Ensure transfer rate compatibility with the attached
devices using the SCSI boot menu command. Check the adapter. Inspect the adapter to make sure it is seated properly
in the PCI bus slot. If necessary, power down the system, reseat
the adapter, and restart the system. Run diagnostics. If a visual inspection of the adapter and cable does
not reveal any problems, or if an action taken as a result of the
inspection does not produce a working adapter, you may want to run
diagnostics to determine whether the adapter can communicate and
respond to PCI bus instructions. Diagnostics are described in the
next section. If diagnostics determine that the adapter is defective, you
must replace it. Contact your local Hewlett-Packard customer representative
or call the HP Response Center.
