Chapter 4 Troubleshooting
After installing AEC-67162M, if it cannot work normally, please follow the checklist
given below to solve the problems.
1. Power status
Check if the power is strong enough for all connected devices. For external SCSI
devices you need to power them on before booting the system.
2. The adapter
Check if the adapter AEC-67162 is inserted firmly into the slot on the motherboard.
If the adapter is fine but cannot be detected, that is usually bad connection. You can
remove the card and insert it into the original or the other PCI slot again.
3. Connectors and cables
Check if all power connectors, SCSI connectors and internal or external SCSI cables
are connected well. Be sure that connector pins aren’t bent, and cables aren’t
damaged because of improper fold.
4. The external cable
If you connect a lot of SCSI devices to the system via daisy chain with an external
SCSI cable but fail constantly, you had better replace the cable with another fine
one, for it might be the cable that causes failure.
5. SCSI ID
Check if each SCSI device has a unique ID number. Don’t let ID numbers conflict
with one another so as to avoid errors.
6. Terminator
If some or all devices on the SCSI bus have been correctly installed but cannot be
detected by the adapter, it is usually the problem of terminator. The possible causes
are lack of terminator, bad installation of terminator, two or more terminators on the
same bus, and terminator of bad quality.
