PART 3 - EXECUTION
3.01
GENERAL
Installation shall meet or exceed all applicable federal, state and local requirements, referenced standards and conform to codes and ordinances of authorities having jurisdiction.
All installation shall be in accordance with manufacturer’s published recommendations.
Copper cables shall be terminated with connecting hardware of same category or higher.
Install plenum cable in environmental air spaces, including plenum ceilings.
3.02
INSTALLATION OF CABLES
General Requirements for Cabling:
1. Terminate all conductors; no cable shall contain un-terminated elements. Make terminations only at indicated outlets, terminals, cross-connects, and patch panels.
2. Cables may not be spliced. Secure and support cables at intervals not exceeding 30
inches and not more than 6 inches from cabinets, boxes, fittings, outlets, racks, frames,
and terminals.
3. Install lacing bars to restrain cables consistently, to prevent straining connections, and to
prevent bending cables to smaller radii than minimums recommended by manufacturer.
4. Bundle, lace, and train conductors to terminal points without exceeding manufacturer's
limitations on bending radii.
5. Use Velcro tie wraps.
6. Do not install bruised, kinked, scored, deformed, or abraded cable. Remove and discard
cable if damaged during installation and replace it with new cable.
7. Cold-Weather Installation: Follow manufacturer specifications for installation and storage
temperatures. Heat lamps shall not be used for heating.
8. In the communications equipment room, install a 10-foot service loop for backbone cabling on each end of cable.
9. Pulling Cable: Do not exceed manufacturer recommended maximum cable pull tensions.
UTP Cable Installation:
10. Do not untwist UTP cables more than 1/2 inch from the point of termination to maintain
cable geometry.
Optical Fiber Cable Installation:
11. Cable may be terminated on connecting hardware that is rack or cabinet mounted.
12. The metal armor of the optical fiber cable must be grounded.

13. Install cabling with horizontal and vertical cable guides in telecommunications spaces
with terminating hardware and interconnection equipment.
14. Suspend UTP cable independently from “Other Trades” and not in a wireway or pathway,
a minimum of 8 inches above ceilings by cable supports not more than 60 inches apart.
15. Cable shall not be run through or supported from structural members or in contact with
pipes, ducts, or other potentially damaging items.
Group connecting hardware for cables into separate logical fields.
