Power Supply Module
Both MGC units (MGC-100 and MGC-50) operate at 100-240 volts
AC 50/60 Hz.
Power Module in the MGC-100
Up to three redundant power supplies (N+1) provide backup for the system to
ensure multipoint service is not interrupted as a result of any single power
supply failure. The Power Supply Modules are hot swappable and connect to
the Powerplane, which is part of the Backplane.
The power supply automatically senses the AC input voltage.
One Power Supply Module is required to power a partially populated system.
Two Power Supply Modules are required to power a full system or a partially
populated system with power supply redundancy.
Three Power Supply Modules are required to power a full system with power
supply redundancy.
The capacity of each power supply module is shown in Table 4-1.
The MGC-100 can accommodate a -48 volt DC power supply. The
mechanical design does not allow 48V power supply modules to be inserted
into a system designed for AC input, or AC power supply modules to be
inserted into a system designed for 48V DC input.
