AEC-67160 Ultra160 SCSI Adapter
Chapter 5 Troubleshooting
When the AEC-67160 Ultra160 SCSI Adapter has installed but not function
properly, please follow by the troubleshooting at below.
1. Check power supply.
When it starts to check the malfunction devices, please check the power status
(ON / OFF).
2. Check host adapter.
Ensure the adapter card is seated properly in the slot on the motherboard.
3. Check all connectors and cables.
Check all power connector, SCSI connector, IDE connector, device power
connector, and ribbon cable are connected well. Ribbon cables are damaged easily
due to un-proper fold. Make sure no connector pins were bent. Ensure pin 1 on the
interface cable is aligned with pin 1 on the drive and host adapter.
4. SCSI ID conflict.
In the occassion of multiple SCSI devices, please ensure an unique ID has set for
each SCSI device. By doing that, it will reduce the chance to get ID switch
malfunction. Therefore SCSI devices can be test individually when there is an error
occured.
5. Problems of poor external cable.
This might happened for the daisy chained with many SCSI devices connected by
the external cables which are not the high density 50 pins (or 68pins UW-SCSI/
LVD) cables. The 25pins to 50 pins SCSI cable has weak grounding, further more if
the daisy chained with many SCSI devices to the system through the 25/50/68 pins
SCSI cable would encounter intermittent failure. Therefore, it is recommended that
you change this cable with another better quality one.
