Each PSM has two input mode switches (DIP switches) on the faceplate. The DIP switches
provide critical information to the power management subsystem to help generate alarms
in case of a feed failure or a wrong connection. Each PSM has an LED per feed indicating
whether the feed is active and whether the feed is properly connected. You must set the
DIP switch on each high-capacity AC power supply according to how many feeds are
connected. When one feed is connected, the system is running in reduced capacity mode.
When two feeds are connected the system is running in full-capacity mode. Use these
DIP switch settings:
Position-0 indicates one AC feed is present
indicates two AC feeds are present
Position-1
