MGC Manager Interface
As shown in Figure 3-4, “MGC unit functional block diagram” on page 3-4,
the Main Control Unit communicates with the MGC Manager through the
LAN interface or the RS-232 interface.
Power Supply Flow
For the MGC-100, the AC power inlet is connected by a switch through a 15
Amp. circuit breaker and then filtered to the AC power supply module. The
DC power outlet delivers 5V, 12V, and -12V through the power bus in the
Backplane to the functional units and the Main Control Module. The 12V is
also delivered to the fans.
For the MGC-50, the AC power inlet is connected through a 12.5 amp. 250
volt fuse and then filtered to the AC power supply module.
