2930M PoE AP-515 power issue



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.

Re: 2930M PoE AP-515 power issue

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?

If my post addresses your query, give kudos:)
