R710: "PoE+" injector still gets recognized as 802.3af power

[john_d]

For fun, I tried buying a PoE+ injector to unlock full transmit power on 2.4GHz on my R710. I found that even with an injector that's advertised to be PoE+, the power mode still says 802.3af, not 802.3at.

Looking at the support article KB-5005, it looks like it's implying that PoE+ negotiation requires a PoE+ switch that speaks LLDP. Is this true? Is there any way to get the AP into PoE+ mode via an injector?

It was alluded to in our posts above. Note that the forced AT command only started showing up a few months ago in SZ first and then undocumented but also present in ZD shortly thereafter. When this thread was created 11 months ago there was as no way to force AT.

Thanks Vito,

    I was about to give up on this and now it works fine in AT mode 🙂

Beware that setting this option via AP CLI may not persist past reboot. This setting is now on the controller side too -- go to Configure -> AP and select the AP. There will be a Power Mode drop down and you can force to AT from there.

Not sure where the setting is in SmartZone.

This post references setting the POE/POE+ mode on a stand-alone AP, therefore setting the option via an AP's CLI may not stay as set (configured) if the AP is connected to and controlled by a ZoneDirector appliance, and your additional comment about where to set it via the ZD appliance's configuration is helpful.

Actually I think I made the post and was ZD managing my R710 at the time 😉

It was because Ruckus's KBAs only offered AP CLI commands which, at the time, were required to enable AT autonegotiation.
