Nonredundant Configuration
One in either PDU can provide power
PSM0
to all fan trays.
If the nonredundant PSM in this zone is not
powered on, the fan trays are not powered
on, and the packet transport router will not
be powered on.
If the nonredundant PSM in this zone fails, the
fan trays are not powered on, which will cause
the packet transport router to be powered off.

Nonredundant Configuration
One in either PDU can provide power to
PSM1
the craft interface, both host subsystems, both
CCGs, and all nine SIBs.
If the nonredundant PSM in this zone is not
powered on, the craft interface, host
subsystems. CCGs, and SIBs are not powered
on.
