3.2.4 Installing the Power Supply Module
You must install at least one power supply module in your
MMAC-M8FNB. One MMAC-M8PSM provides sufficient power for
many MIM configurations, but you may choose to install the more
powerful M8PSM-E for some MIM configurations, or the M8PSM-EDC
for use with a DC power source; with any model, you can also install a
second power supply as a redundant and/or load-sharing power
source. (Note that the power requirements of some FDDI
configurations require dual power supplies.) When two power supply
modules are installed, the load is evenly distributed; if one power
supply fails for any reason other than a shorted DC backplane, the
second power supply assumes the load, if it can, even when one
M8PSM and one M8PSM-E are installed in the same chassis.

An M8PSM-EDC power supply cannot be installed in
the same chassis as an M8PSM or M8PSM-E.
