14. Each patch panel shall utilize a rear organizer for holding the cables as they route to
the punchdown field.
15. Cables shall be bundled in groups of 4 as they route through the rear cable organizer.
16. When terminating cables, ensure that the smallest amount of jacket is removed from
the final termination point of the cables.
17. Pair twists shall be maintained up to the IDC jack for all the cables.
18. When terminating cables on the back of patch panels, or on modular jacks, use only
single point, 110 style punchdown tools. Multiple pair punchdown tools are not
permitted for terminating individual 4 pair cables.
19. Provide a service loop of the cables on the vertical cable ladder. The loop shall
extend no less than 1 foot below the termination point on the patch panel. Route the
cables 1 foot below the patch panel, and then back up to the panel. This will provide
room for future moves and additions to the rack.
20. Each cable shall have a self adhesive, self laminating, laser printed label at each
end. The label shall show the location identifier of that cable. Labels shall be
installed no more than 4 inches from the termination point of the cable.
B. CAT-6 data/voice jacks shall be installed at the user end of each CAT-6 cable installed in the
system.
1. Jacks shall be installed to provide minimal signal impairment by preserving wire pair
twists as close as possible to the point of mechanical termination.
2. Jacks shall be installed according to manufacturer’s instructions and properly
mounted in plates, frames, housings, or other appropriate mounting devices.
3. Jacks shall be installed such that cables terminated to the jacks maintain minimum
bend radius of at least 4 times the cable diameter into the workstation outlet. Cables
shall be terminated on jacks such that there is no tension on the conductors in the
termination contacts.
4. All voice/data jacks shall be office white unless noted otherwise.
C. Surface Mount boxes
1. Jacks and/or connectors shall be terminated to the appropriate cable and inserted in
the correct orientation into the surface mount box.
2. When the surface mount jack is mounted above the ceiling the cable shall be coiled
and the cable and surface mount box shall be kept off of the ceiling grid
3. Attach the coil to the building structure with a plenum rated tie-wrap.
4. Label each surface mount box for the cable number. Also install a wrap-around label
on each cable.
5. When attaching a surface mount box to a piece of furniture or to a power pole the
contractor shall drill a hole in the furniture/pole that is larger than the hole on the back
of the surface box.
6. Screw the surface box to the furniture or to the pole. Adhesive only solutions are not
adequate.
D. Proper support of cables is of paramount importance when installing a cable infrastructure.
All cables not in conduit or cable tray shall be supported via J-hooks a minimum of every 5
feet.
1. Routes of cables shall be parallel or perpendicular to the walls of the building.
2. Install the J-hooks to minimize changes in the level of the cables as they route
through the J-hooks.
3. Do not install more than 50 cables in any 1 J-hook. Provide additional hooks where
more than 50 cables route along a main route.
4. All communications shall route as high in the ceiling as possible while still being
accessible and staying away from other utilities.
5. When installing the cable through the J-hooks, they shall all have relatively the same
droop between hooks. All cables shall be installed neatly and squarely.
6. Secure the J-hooks to the building structure with beam clamps and threaded rod as
required to support the cables.
7. J-hooks shall never be attached to drop ceiling support wires. Cables shall never be
