October 2002
Position the Media Gateway Stacks
!
CAUTION:
Lifting the media gateway may require 2 people, as it may weigh as much as 130 pounds
(60 kilograms). Use caution to avoid injury.
Before beginning the media gateway installation, check the location of the AC/DC power
receptacles. The receptacles must be on separately fused circuits not controlled by wall
switches. They must be located within 10 feet (3 meters) of the media gateway, and outside the
Main Distribution Frame (MDF) area.
Refer to the serial numbers and lettered designation strips in the Customer Service Document
(CSD) when stacking the media gateways. If earthquake protection is required, skip to ‘‘Install
Earthquake Protection for Avaya SCC1 Media Gateway’’ on page 103. Return to this section
when finished.
Perform this step first for all standard reliability media gateway stack installations.
