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.
