Connexion with PoE Cisco

I have a problem to feed cisco access points (AIR-AP1131G-E-K9) with switch M4100-26G-PoE.

error message :

WARNING ALL RADIOS DISABLED

LOW_POWER_CLASSIC_NO_INJECTOR_CONFIGURED (M4100-26G-POE on port xxxx.xxxx.xxxx)

  • From old wally brain the Cisco AP have some power injector status settings in the advanced section. Whatever was in the heads of the designers, if it is set to "Installed" the MAC of the PoE upstream switch is retained, and needs to be re-learned once moved to another switch. Nasty WAC admins might have set it to "Foreign", so it's also locked to a specific PoE upstream switch, too. Only "Override" will make it behave like a more common standard PoE device, always receiving power - and allowing to bring up the radios.

     

    Not a Netgear PoE switch issue at all...
