General Procedure

The A4800A 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 A4800A adapter:

Step 1. 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.

Step 2. Check SCSI bus compatibility.

Ensure transfer rate compatibility with the attached devices using the

SCSI boot menu command.

Step 3. 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.

Step 4. Run diagnostics.

If a visual inspection of the adapter and cable(s) 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 controller is defective, you must replace

it. Contact your local Hewlett-Packard customer representative or call

the HP Response Center.
