MGC+ Hardware and Installation Manual

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

Three redundant power supplies 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. Two Power Supply Modules are required to power a full system.

Three Power Supply Modules are installed on the MGC+, with one power supply providing redundancy. Should one power supply fail the other two power modules are sufficient to power the MCU.

The capacity of each power supply module is shown in Table 4-1.
