Hello Experts,
Thanks in advance for the help. I have a Cisco Aironet 1552e-a-k9 That will be powered by a cisco power injector "AIR-PWRINJ1500-2. The AP will be pole mounted
outside our building, The power injector will be in the Computer room. My Part in this Job is to get all hardware ready for now. I was supplied all the cable and hardware from a 3 party vendor. I was reading the specs for the cable and it seems
I need shielded 26 AWG for the power Injector(ONLY) according to the cisco directions. The directions do not give any wiggle room on the cable.  I was supplied non shielded Indoor/outdoor 24 awg cat 6 Jelly filled cable.
  Before you ask, Yes I do have a surge gate Between AP and the power Injector.
My Question is what Kind of cable is best for this? What does everybody else use with a power injector? If I used the cable they gave me I think I might be looking at problems. Any Help would be Great.

Thanks
Chris

There are two main things here...

1] The Ethernet cable should be 26AWG or larger to mitigate the risk of fire.
2] The Ethernet cable must be shielded and rated for external use.

A 24AWG cable is actually better than a 26AWG cable, in that it's a slightly larger cable and therefore can carry slightly more current.  This is important to help mitigate the risk of fire, but you'll not notice any operational difference really.  Keep it - it's perfect.

Thanks Craig, Cisco left out the "OR BETTER" in the manual. I ended up with a 1000' roll of unshielded cable I cant use now. Go Figure. One more quick question, Because this will be outside, Is is correct I should be using the Jelly filled cable? Any Recommendations, I have 3 buildings I have to do,  Also I have been thinking about using the hole for the fiber connection that we will not be using for a permanent connection for the console cable, it would be a bummer having to go on a roof with a laptop and hook in that way, You see any problems with doing it like that?

Thanks Chris
