MAP 2030: 7133 – Remote Power On Control Feature
This MAP helps you to isolate FRUs that are causing a power problem when a Remote
Power On Control feature is installed. See the using-system Installation and Service
Guide for information about how the using-system power-control cables are connected.
Attention: Unless the using system needs to be turned off for some other reason, do not
turn 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.
