I would open a support case. There were some 7982's with POE issues. ... A problem with the POE chips.

Hi Luis,

Are you using a Ruckus PoE injector? The model number for Ruckus PoE injector is NPE-5818 which has Input: 48V – 1.25 A.

Make sure that you connect the APs's PoE port to the port named as ÄP/Bridge"and not "Network" of the Ruckus PoE injector.

if yours is NOT powering on Ruckus's own POE injector then would suggest RMA them..

i had some problems also with POE injector or switch, i used some HP pro curve
HP 2915-8g poe switch and i used to have the same problem because HP didn't respect the poe spec,
Now i used cisco poe switch and no more problems,
You can try to start you AP with the ac adapter (and the poe cable insered )and when the ap is running unplugged the ac cord, i try this on a setup and it work.

Test powering the APs with a new/different cable, and from a PoE switch if you have one (and apart
from other devices if you can, to assure full PoE).

Ruckus PoE injectors should work.  And 7982s will power from standard 802.3af from most
switches.  (test by not having them directly next to or above/below another PoE device, to
get full switch capacitor output)  They should work in any port of 802.3at power switches.

If you determine you have bad PoE injectors, we'll swap them without having to ship APs.
