2930M PoE AP-515 power issue

    Posted Nov 20, 2019 11:09 AM

    Hi,

     

    I am not very familar with the aruba switching platform but I just got a 2930M ROM67A so I'm using it in my lab to provision a bunch of AP-515. However I am not able to get the APs to get online. I enabled lldp with lldp run but:

     

    1. The AP is only negotiating 9.3W

     

    What is going wrong here? I feel this is something really stupid.

    Is the device successfully identified by LLDP?

     

    show lldp info remote-device [INTERFACE]

    Asking the obvious, but you are using E0 on the AP and not E1?

    My issue was DHCP actually.

     

    But make sure that you're connected in ENET0 and that you have LLDP enabled.
