This MAP is used for problems that still occur after all FRUs indicated by the SRN or error code have been exchanged.
Use this MAP for problems that still occur after all FRUs indicated by the SRN or error code have been exchanged.
Some external devices (including rack drawers that contain devices) have their own problem determination procedures. If the problem is related to an external device that has its own problem determination procedure, run those procedures if not already run. If they do not correct the problem, continue with this MAP.
The problem may have been caused by a resource that has not been tested. System Checkout tests all resources. If the online Diagnostics are installed and you are able to load them, then All Resources under the Diagnostic Selection menu should be run. If you get a different SRN, look up the SRN in the SRN chapters and perform the listed action. If you are unable to run All Resources under the Diagnostic Selection menu or you do not get another SRN when running it, continue with this MAP.
If the problem is related to a SCSI device, SCSI bus, or SCSI controller, go to MAP 0050: SCSI bus problems. If you are unable to isolate the problem with MAP 0050, continue with Step 0030-4.
| Failing Resource | Repair Action |
|---|---|
| SCSI Device | Exchange the SCSI controller. Replace the power supply. |
| Pluggable SCSI or IDE controller | Exchange the backplane into which the adapter is plugged. |
| Keyboard, tablet, mouse, dials, LPF keys, diskette drive | Check the cable attaching the device to its adapter. If you do not find a problem, exchange the device's adapter. |
| Pluggable adapters, CPU cards, and controllers | Determine whether the adapter contains any attached FRUs such as fuses,
DRAMs, and crossover cables.
|
| System and I/O backplanes | Contact your service support structure. |
| Built-In system ports | Replace the service processor if present. |
| A device attached to the system by a cable and an adapter. |
|
| IDE Device | Replace the cable between the IDE controller and the device. If the IDE controller is packaged on a backplane, replace that backplane, otherwise replace the adapter containing the IDE controller. |
