PoE on SF-300-24P to AIR-AP1231G

Unanswered Question

Hi,



I have a problem with switch SF-300-24P and AIR-AP1231G-E-K9.


The AP is working fine in a switch 2960 or 3560, and I want to move it to a new SF-300-24P.


When it is plugged in SF-300, the AP never get boot up , it obtains power, and blinks its leds, its boot process begin, but it get into a loop, and it's never gets boot up.

If I connect a external power supply to AP while it's booting, the AP gets boot up, and then it work's fine. Even, If i unplug the external power, the AP goes on working fine.


You know about this problem ? What I can do ?

Hi Jose, please upgrade software of the switch to 1.3.5.58 then factory default it. I recommend do not use a back up config, config from scratch. This should resolve that.
