Space requirements and layout

Before installing the main distribution frame (MDF) 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
110-type hardware
Cable Slack Manager
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 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 = two Cable Slack
Managers and 2.5 = three Cable Slack Managers).
Note:
Cable clamps are required in installations with Cable Slack Managers. At the rear
Note:
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 MDF cables
in place.
