Description
Configure the I/O drawer
Update the I/O drawer routing table of RIO
ports
Action/
Possible Failing FRU
1. Check the RIO cable specified by the
location code. If the location code
specifies an I/O subsystem or its RIO
connector card, check the RIO cables
going into and out of the I/O subsystem.
2. Verify that the entire RIO loop
associated with the location code is
cabled correctly.
3. Replace the RIO cables specified by
the location code. If the location code
specifies an I/O subsystem or its RIO
connector card, replace the RIO cables
going into and out of the I/O subsystem.
4. Replace the RIO connector card
(location: U0.dd-P1.1) in the failing I/O
subsystem. This is the I/O subsystem to
which the cable replaced in step 3 is
attached.
5. If the location code associated with this
checkpoint specifies a PCI adapter
card, replace the adapter card.
6. Replace the I/O subsystem backplane
(location: U0.dd-P1) in the failing I/O
subsystem. This is the I/O subsystem to
which the cable replaced in step 3 is
attached.
