For redundant operation it is recommended to connect each of the Ethernet connectors to a different switch.

Connecting the Power Supply

Connect the V7122 gateway to the power supply using one of the following methods:

Connecting the AC Power Supply

To connect power when using a single AC power cable:

ƒAttach one end of the supplied 100/240 VAC power cable to the rear AC socket and connect the other end to the correct earthed AC power supply.

WARNING:

Units providing power sockets with three pins must be connected by service personnel to a socket-outlet with a protective earthing connection.

To connect power when using a dual AC power cable:

1Before connecting the dual AC power cable, see the note below.

2Attach one end of the supplied 100/240 VAC power cables to the rear AC sockets and connect the other end to a separate earthed mains circuits (for power source redundancy).
