100 Installing the Avaya S8700 Media Server with an Avaya G650 Media Gateway
December 2003
CAUTION:
The auxiliary contacts inside the EPO switch assembly must close when the switch is
pressed. This contact closure energizes the relay inside the power distribution unit,
causing the connection to the battery holdover assembly to open.
Figure 22, External alarm cable connection,
on page 102 shows the cabling from the auxiliary
contacts inside the EPO switch assembly and how they connect to the internal relay.
3 Connect the RPO wires to the auxiliary contacts on the EPO switch. See Figure 22, External
alarm cable connection, on page 102.
NOTE:
The EPO switch and the auxiliary contacts for the RPO connection are customer-supplied.
