contact_abdul · ‎01-19-2009

This sounds silly but still i ask to be safe in my project.I want to use Cisco 1250 LAP with wireless controller.I want to use POE facility.There are around 7 1250 seried LAP AP.My question is :

01.Suppose the farthest access point (cisco 1250 with wireless n & around 5-6 DBI Omni Antenna) which needs power on poe is 110 meters away from poe switch.I want to use normal cat 6 utp cable to connect the A.P.

(a)How many meters maximum cat 6 utp needed to support poe? How should I check how much is dc voltage loss at the end of the A.P due to long cat 6 cable?

Thanx in advance.

100 Meters (90 "in the wall," Solid conductor, + up to 5 meters of jumper cordage ,stranded conductor at each end, is the spec for TIA/EIA 568 structured cabling (and hence, POE).

If this is a commercial project, you may need to adjust your design accordingly, or you would be out of specification, for whatever liability that might present in your situation.

Good Luck
