Telecommunications Room Termination Equipment
2.1
Termination floor-standing racks, wall racks and cabinets shall be industry standard
19" equipment (relay) racks. The preferred equipment configuration is at least three
Chatsworth floor racks (one for active electronics, one for copper cable terminations,
and one for fiber terminations) with double sided Chatsworth vertical wire management
units mounted between racks, with wire managers on both sides of all cable termination
racks. The fiber termination rack shall be located closest to the wall. Floor racks
shall be bolted to the floor, to each other and braced to the ceiling or walls to
meet seismic standards. Racks and cable trays shall be grounded as per TIA/EIA Standard
607-A Commercial Building Grounding & Bonding. Part numbers for Chatsworth racks are
as follows:
Chatsworth Universal Rack |
46353-503 |
Chatsworth Wire Management Unit |
11729-503 |
Chatsworth Wall Mount Rack |
11960-512 |
If UIT has been determined to use a wall- mounted rack or cabinet, select the appropriate
size and style of rack/cabinet to meet the needs of the cable terminations, electronics,
and the available space. If the telecommunications room is not in a secure area, lockable
cabinets shall be used. Conduits holding cables must meet and secure at the cabinet,
and a dedicated electrical outlet will be mounted inside the cabinet so no access
can be gained to the equipment or cabling except through the cabinet door. For small
installations, use a Wall Mounted Cabinet with 19” swing rack inside and deep enough
for electronic equipment. When there is adequate space, use 1 or more floor standing
lockable cabinets, if a dedicated telecommunications room is not possible.
2.2
Commscope patch panels shall be installed on the racks to terminate the Unshielded
Twisted Pair (UTP) horizontal wiring. Commscope Category 6A high density patch panels
or unloaded kits, black in color as follows:

The layout of jacks in the rack patch panel shall have station cables grouped numerically by room number, terminated adjacent to each other, and jack locations will not be split between rows or patch panels.
