128 Installing the Avaya™ S8700 Media Server with Avaya™ MCC1 or SCC1 Media Gateway

Space Requirements and Layout

Before installing the Main Distribution Frame and other equipment in the equipment room,
make sure there is adequate space and there is a plan for placing the equipment.

Installation Space Requirements

Make sure there is adequate space for the following pieces of equipment:
''Sneak Fuse Panels and Emergency Transfer Units'' on page 128
•
• ''110-Type Hardware'' on page 128
''Cable Slack Manager'' on page 128
•
Sneak Fuse Panels and Emergency Transfer Units
You need about 8 inches (20 centimeters) of horizontal wall space for each column of sneak
fuse panels. Horizontal wall space must also be provided for emergency transfer units.
110-Type Hardware
The trunk/auxiliary field and the distribution field are mounted on the same wall. Each
110P-type terminal block is 8.5 inches (21.6 centimeters) wide. Vertical patch cord troughs are
5.31 inches (13.4 centimeters) wide and horizontal patch cord troughs are 23 inches (58.4
centimeters) wide.
Each 110A-type terminal block is 10.8 inches (27.4 centimeters) wide; however, no horizontal
patch cord troughs are used and the blocks are shorter than 110P-type terminal blocks. This
allows the 110A-type terminal blocks to be stacked. Therefore, the 110A-type hardware
requires less space than the 110P-type hardware on a per-station basis.
Cable Slack Manager
A Cable Slack Manager is 32 inches (81.3 centimeters) wide. Slack managers are commonly
used in installations consisting of media gateway stacks, such as the SCC1 media gateways.
Determine the quantity of slack managers by dividing the total length of the Main Distribution
Frame (MDF) in inches (centimeters) by 32 (81.3). A partial number of 0.4 or less should be
rounded down, and a partial number of 0.5 or more should be rounded up (for example: 2.4 = 2
Cable Slack Managers and 2.5 = 3 Cable Slack Managers).
NOTE:
Cable clamps are required in installations with Cable Slack Managers. At the rear of the
media gateways, on each rear ground plate, install two cable clamps using the screws
provided. These clamps hold the 25-pair input/output or Main Distribution Frame (MDF)
cables in place.
