Installation Space Requirements

This section has information about

Sneak Fuse Panels and Emergency Transfer

Approximately eight inches (20 cm) of horizontal wall space is required 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 cm) wide. Vertical patch cord troughs are 5.31 inches (13.4 cm) wide

and horizontal patch cord troughs are 23 inches (58.4 cm) wide.

Each 110A-type terminal block is 10.81 inches (27.4 cm) 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 cm) wide. Slack managers are commonly used in installations

consisting of cabinet stacks. The quantity of slack managers is determined by dividing the total length of

the Main Distribution Frame (MDF) in inches (cm) 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).

Cable clamps are required in installations with Cable Slack Managers. At the rear of the

cabinets, 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
