Cisco AIR-CAP2702 getting Medium Power on 2930F

    Hello people,

     

    When I connect Cisco AIR-CAP2702 Access Points to Aruba 2930F switches, 9 times out of 10 they come up with "Medium Power (15.4W)". Rarely they manage full power.

     

    Things I have tried:

     

    • Activate ”Pre-standard 802.3af switches” on APs
    • Activate ”power-over-ethernet pre-std-detect” on switches
    • Configure ”power-over-ethernet critical” on switches' interfaces towards AP’s
    • Deactivate LLDP on switches' interfaces towards AP’s

    None of it made any difference.

     

    Have anybody experienced (and solved) anything similar?

     

     

    Lars

    Greetings!

     

    Could you provide the output of 'show power-over-ethernet' and 'show power-over-ethernet <port>' so we can see how the switch is allocating power to the port, and the available power budget?

     

    Also, if there are any log entries being generated when an AP is connected, a sanitized version of those may also be useful.

    Solved it.

     

    On the switchport connected to the AP, you need this configuration:

     

    poe-lldp-detect enabled

    It will come up as low power, transition to medium power and finally settle on full power.
