MAP 2410: 7133 Models D40 and T40 – Repair Verification
This MAP helps you to verify a repair after a FRU has been exchanged for a new one.
Attention: Unless the using system needs to be switched off for some other reason, do
not switch off the using system when servicing the 7133 or an SSA link. Power cables
and external SSA cables that connect the 7133 to the using system can be
disconnected while that system is running.
Step 1.
Before you arrived at this MAP, you might have exchanged one or more FRUs
for new FRUs. Some of those FRUs have Power lights (for example, disk drive
modules and power supply assemblies). Check whether all those Power lights
are on.
Do all the FRUs you have exchanged have their Power lights on (where
applicable)?
NO
a. Exchange, for a new one, the FRU whose Power light is off.
b. Go to step 2.
YES Go to step 2.
Step 2. (from step 1)
Are all Check lights off or showing green?
NO Go to “MAP 2010: 7133 Models D40 and T40 – START” on page 87.
YES
a. Run concurrent diagnostics to the device that reported the
problem.
If the original problem was not reported by a device, run
concurrent diagnostics to each SSA attachment in the using
system. For information about how to run concurrent diagnostics,
see Concurrent Diagnostics in the “Additional Information”
appendix (in this book) for your using system.
If the diagnostics fail, return to “MAP 2010: 7133 Models D40 and
T40 – START” on page 87.
b. Run the appropriate service aid or function to ensure that the error
log entry for the problem that you have just corrected does not
cause an SRN to be generated when diagnostics or error log
analysis is run in the future. See Problems Corrected in the
“Additional Information” appendix (in this book) for your using
system.
