1) ROUTER 1 port is used for connection to the Router as standard.
Use ROUTER 2 port if the MPS firmware is V1.5.20 or earlier.
2) ROUTER 2 port is used for connection to the 'B' Router in a dual interface connection
with 'A' and 'B' Routers.

indications and controls should have dual power supply: one power supply connected
to ROUTER 1 port, and the other power supply to ROUTER 2 port.
