An IBM option that
previously worked does
not work now.

Action
Verify that all option hardware and cable
connections are secure.
If the option comes with its own test
instructions, use those instructions to test the
option.
If the failing option is a SCSI option, verify that:
1. The cables for all external SCSI options are
connected correctly.
2. The last option in each SCSI chain, or the
end of the SCSI cable, is terminated
correctly.
3. All external SCSI options are turned on.
External SCSI options must be turned on
before the system is turned on.
For more information, see the SCSI
documentation that came with your SCSI device
or devices.
If this does not correct the problem, contact IBM
technical support.
