Installation Requirements

Sneak Fuse Panels and Emergency Transfer Units

Approximately 8 inches (20 cm) of horizontal wall space is required for each column of sneak fuse panels. Up to 25 connector pairs can be protected by each panel. 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. The quantity of which is determined by dividing the total length of the 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

0.5or 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 cabinets, on each rear ground plate, install 2 cable clamps using the screws provided. These clamps hold the 25-pair input/output or MDF cables in place.
