Checkpoint Description Action or
possible failing FRU
E56B Set up RIO interface chip registers If the location code associated with this
checkpoint is either U0.1-P1 or U0.1-P2, do
the following:
1. Replace the PCI riser card in the CEC
drawer, location: U0.1-P2.
2. Replace the CEC backplane: location
U0.1-P1.
Otherwise, replace the device specified by
the location code.
E56C Set up the RIO interface chip PCI bus If the location code associated with this
checkpoint is either U0.1-P1 or U0.1-P2, do
the following:
1. Replace the PCI riser card in the CEC
drawer, location: U0.1-P2.
2. Replace the CEC backplane: location
U0.1-P1.
Otherwise, replace the device specified by
the location code.
E56D Identify devices on current bus If the location code associated with this
checkpoint is either U0.1-P1 or U0.1-P2, do
the following:
1. Replace the PCI riser card in the CEC
drawer, location: U0.1-P2.
2. Replace the CEC backplane: location
U0.1-P1.
Otherwise, replace the device specified by
the location code.
E56E Begin initializing the service processor
control chip If the location code associated with this
checkpoint is either U0.1-P1 or U0.1-P2, do
the following:
1. Replace the PCI riser card in the CEC
drawer, location: U0.1-P2.
2. Replace the CEC backplane: location
U0.1-P1.
Otherwise, replace the device specified by
the location code.
