PWRREG
A power regulator card may be failing.
Attention: To avoid thermal damage to other cards when exchanging regulators,
you must put the EMC shield for the CEC regulator in place before powering on
the system.
Perform any SPCN-PIPs before exchanging parts.
Attention: AC power must be removed from the system before removing or
installing regulator 3.
Note: The C in the SRC (1xxC xxxx) indicates the problem is on the system
processor Frame.
Perform the following to determine the part number for the failing power
regulator:
1. Is the SRC 1xxC xxxx?
Yes No
↓ Go to step 6 on page 574 of this procedure.
2. Find the URC in the following table and exchange the part that is listed for
