The MIP FRU group table lists the FRU groups likely to be called in this manual.
¹
Each FRU group contains from one to three FRUs, listed by name and location.
¹
The “1st FRU” is the most likely to be failing; the “3rd FRU” is the least likely.
¹
Usually, only one FRU in an FRU group is failing, and you should try to reduce the FRU group to
the one failing FRU.
¹
If you can reproduce the 3746 failure, exchange FRUs one at a time until the failing FRUs are iso-
lated.
¹
As soon as you have recorded the FRU(s) and LOCATION in the FRU GROUP, go to “3746-900
Maintenance Using a FRU list” on page 1-28 for 3746-900 problem.
ALWAYS
¹
Ensure that the failing area of the machine is available for service.
¹
Consult the “Exchange Precautions” on page 4-1 before removing any FRUs.
¹
Check for loose cards, cables, and crossovers before exchanging FRUs.
¹
Run diagnostics after any repair action.
¹
Follow the 'CE leaving' procedure before returning the machine to the customer.
The FRU group table starts on next page.
