Backplane

The Backplane is based on the “universal slot” concept, where any card can be inserted in any slot. Therefore, different configurations are formed based on the users’ port capacity and functionality requirements. The Backplane supports hot swapping of Function Modules and I/O cards.

In the MGC-100, the front of the Backplane contains 16 slots for Functional Modules and an additional slot (Slot A) for the Main Control Module. The back of the Backplane contains 17 slots for I/O cards (16 slots for I/O and one “dummy” slot). The Network Interface Modules connected via the Backplane to I/O cards, which connects the system to the network. The Power Supply Module provides power to the Backplane via a power bus.
