Installing an Avaya SCC1 Media Gateway Stack
October 2002
Install Rear Ground Plates (Media Gateways
with Earthquake Protection)
Ground plates are installed between stacked media gateways, provide the ground connection
between media gateways, provide radio frequency (RF) radiation protection, and help stabilize
the media gateways.
1 Loosen the four screws at the bottom of the top media gateway and at the top of the
media gateway underneath it. See ‘‘Rear Panel Screw Locations’’ on page 122
.
2 Align the mounting holes in the rear ground plate over the bottom screws in the top
media gateway. See ‘‘Rear Ground Plate and Front Plate or Media Gateway Clip — Side
View’’ on page 124.
3 Align the mounting holes in the ground plate with the four holes at the top of the media
gateway below the top media gateway. Slide the mounting plate down to seat on the
screws.
4 Check all Time Division Multiplexing (TDM) bus cables and the Inter- Cabinet Cables
(ICC) to be sure they are not pinched by the plates.
5 Repeat Steps 1-3 until the rear ground plates are installed between all stacked media
gateways.
6 Do not tighten the screws yet.
