Checkpoint Description Action/
Possible Failing FRU
E541 Initialize the routing table
1. Replace the RIO cable specified by the
location code.
2. Replace the RIO riser card that the
failing drawer is attached to.
3. Replace the RIO riser card (location:
U0.dd-P1.1) in the I/O subsystem that
the RIO cable in step 1 is attached to.
4. If the location code associated with this
checkpoint specifies a PCI adapter
card, replace the adapter card.
5. Replace the I/O subsystem planar that
the RIO cable in step 1 is attached to.
6. Go to “MAP 1540: Problem Isolation
Procedures” on page 124.
E544 Enable the RIO ports
