AP-105 - 802.3af vs 802.3at (PoE+) - any differences in behaviour


We have a pile of AP-105s which have been working fine on 802.3af PoE, provided by a mix of HP, 3com, Extreme and Cisco switches, as well as PowerDsine 3001GC midspans.

We've had anecdotal comments from users about drop-out of connections and been advised by our reseller that we should be using 802.3at (PoE+) to power the AP-105s, otherwise we might have performance limitations - less range or fewer users allowed.

The spec. sheet that comes with the AP-105 just states that 802.3af is required; the web page technical specs. state that 802.3af / 802.3at / PoE+ are supported. However, what isn't stated is if there is any difference in performance or limitations, if "standard" 802.3af (15.4W) is used, as opposed to 802.3at (25.5W).

Do Aruba have a definitive statement on this and is there any reason to push 802.3at?

Bob, there is absolutely no need for the AP-105 to require 802.3at. The
guidance from your reseller is, unfortunately, misguiding at best in
this case. You could have your reseller consult with their Aruba SE to
get in sync.

The AP-105 requires 12.5 Watts, well under the 15.4 Watts that 802.3af

Thanks for the clarification - this is as we suspected.
