MAP 1550: Power Distribution Bus - Power MAP
Purpose of This MAP
Note: This MAP is not a start of call MAP. Use this MAP only if you are directed
here from a MAP step in the
Diagnostics Information for Multiple Bus
Systems
.
If the rack contains more than one power distribution bus, use this MAP to
test the power distribution bus that is connected to the failing drawer. If you
cannot determine which power distribution bus is connected to the failing
drawer, use this MAP to test the first power distribution bus, and then test the
other power distribution bus until the problem is determined.
This procedure is used to locate power problems in the power distribution bus (PDB).
If a problem is detected, this procedure will help you to isolate the problem to the
failing field replaceable unit (FRU).
