Uninterruptible Power Supply; Media Gateway Power Switch - Avaya S8700 Manual

Uninterruptible Power Supply

A recommended Uninterruptible Power Supply (UPS) may be used for power holdover. The
type of UPS depends on the holdover requirements. Total holdover capacity varies depending
on the UPS. The UPS must provide surge protection for the RMC.

CAUTION:
The major alarm contacts are designed to be connected ONLY to a UPS that can indicate
that it is on backup power. For most non-Avaya UPSs, you should not use the major
external device leads.

2 Ensure that the media gateway is connected to an "unswitched" or "always on" electrical
outlet on the UPS.
3 For an Avaya UPS, connect and administer the UPS.
NOTE:
If an Avaya UPS is wired as recommended, holdover time for each power outage is 1
minute before an automatic shutdown. UPS may handle any subsequent power outage
based on its total battery capacity.

DANGER:
The latch on the power supply acts as the DC power switch and only removes DC
power from the the backplane, not the AC power. To remove the AC power from the
media gateway, pull the AC power cord from the back of the media gateway.
