I might also add that many local codes require that plenum rated cabling be used when the cables are run through a plenum. Plenum is normally the space above a suspended ceiling or below a raised floor. Plenum cable is more resistant to fire and does not emit toxic fumes when exposed to high heat. Because of these requirements, plenum rated cable it is more expensive and stiffer than regular cable and hence many installers prefer not use it. Local codes should be checked to avoid future re-installation and/or potential liability.

You should consider several factors when determining how each cable run will get from point to point. Avoid running cable near electrical wiring. If you must cross electrical wiring, make the network cable cross perpendicular to the wiring to minimize crosstalk and interference, which degrade network performance. Route Cat 5 cables several feet away from fluorescent lighting fixtures where possible for the same reason. Secure cables with wire hangers, wire ties, or wire staples. If you buy a rack to hold the hub and patch panel, use wire ties to bind cables to the rack and relieve strain on the connections to the hub. If using wire staples, be careful not to run the staples through the cable. You don't need to run Cat 5 cables through conduit, and network cables can run as a bundle without concern for crosstalk between them. Don't run Cat 5 cable through ventilation ducts; the cable insulating sheath gives off toxic fumes if it gets hot enough to burn. -------- Original Message -------- Subject: [RBASE-L] - Off topic Network Q From: "MDRD" <[email protected]> Date: Mon, October 05, 2009 9:59 am To: [email protected] (RBASE-L Mailing List) Hi I have heard you should have your Cat5 cables 4ft away from fluorescent lights but the electrician wiring my new office says it is not necessary. Is there any info from major companies that I can give him or am I being overly concerned? Thanks Marc
