RadioFrame System Method of Procedure GSM/802.11b
Pre-Installation
42 RadioFrame Networks, Inc.
For simplifying installation and reducing cable runs, a single CAT-5 cable may be run
from the equipment room hub to an additional hub in the computer workstation area for
distribution to the individual computers. This can reduce the number of cables required
between the equipment room and the individual computers. Refer to ANSI/TIA/EIA-569-A
for more information.
3.8.4.1 NEC Compliance
All RadioFrame Networks products and equipment are NEC compliant.
3.8.4.2 Local Jurisdictions
Local jurisdiction codes shall apply and override any other requirements specified in this
document.
3.8.4.3 Routes
Consideration should be given to using some method of cable management and
containment for runs of CAT-5 cable. Such methods can be dedicated cable runs, lay-in
wireways, cable runways and conduits. Refer to ANSI/TIA/EIA-569-A and CSA-T530 for
more information.
CAT-5 cable shall not be installed in the same conduit, cable runway, outlet box, or
similar device with AC power cables, unless separated by a barrier as allowed in NFPA
70, Article 800-52. Doing so can be unsafe and is likely to cause EMI onto the CAT-5
cable, causing network errors. Refer to NFPA 70, Article 800-52, ANSI/TIA/EIA-568-A,
and CSA-T529 for more information.
Precautions should be taken to avoid routing CAT-5 cable near sources of EM/RFI. Such
noise sources may be electrical power wiring, dimmer switches, radio frequency
transmitters, motors, generators, and fluorescent lights. Precautions may include,
increasing the physical distance between the CAT-5 cable and the source of the EMI/RFI,
installing the CAT-5 cable inside of a grounded metallic conduit, or use of a CAT-5 100-
ohm screened twisted pair cable as permitted by ANSI/TIA/EIA-568-A. Routing cables
near sources of EMI/RFI can cause data errors and degraded system performance. Refer
to ANSI/TIA/EIA-568-A and CSA-T529 T530 for more information.
Cables shall be separated by at least 5.1 cm (2 in.) from AC power conductors. Refer to
NFPA 70, Article 800-52 for more information.
CAT-5 cables installed in ducts, plenums, and other air-handling spaces shall be installed
in accordance with other sections of this document and NFPA 70, Article 300-22. Also
refer to NFPA 70, Article 645.
CAT-5 cables installed in hazardous areas as defined in NFPA 70, Article 500 shall be
installed in accordance with NFPA 70, Article 500 and any other applicable electrical and
building codes.
CAT-5 cable shall not be attached by any means to the exterior of a conduit or other
raceway as a means of support. Refer to NFPA 70, Article 725-54 and NFPA 70, Article
800-52 for more information.
