Checkpoint Description Action/
Possible Failing FRU
E52B The RIO cable connected to the RIO port
has been detected
1. Check the RIO cable specified by the
location code. If the location code
specifies an I/O subsystem or its RIO
interface, 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
interface, replace the RIO cables going
into and out of the I/O subsystem.
4. Replace the RIO riser, U0. dd -P1.1, in
the I/O drawer that the RIO cables in
step 1 are attached to.
5. Replace the CEC backplane, U0.1-P1.
6. Go to “MAP 1542: I/O Problem
Isolation” on page 127.
E52F End of configuration of the RIO hub
1. Check for system firmware updates.
2. Go to “MAP 1540: Problem Isolation
Procedures” on page 124.
E530 Checking RIO hub ports on current RIO
hub
1. Check for system firmware updates.
2. Go to “MAP 1540: Problem Isolation
Procedures” on page 124.
E531 Get RIO hub node ID
1. Replace the RIO-2 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-2 cable in step 1 is attached to.
6. Go to “MAP 1540: Problem Isolation
Procedures” on page 124.
