AP550's are running in AF power mode.

adam_clegg · ‎03-05-2019

I was able to get AT power running on the AP550's by using the following command:

"no lldp config <port#> dot3TlvEnable poeplus_config" as of right now it is stable.

This is were I found the information:

https://www.reddit.com/r/networking/comments/4dl6rv/hp_2530_2448_port_poe_not_delivering_poe/

This essentially disables LLDP PoE+ negotiations and the AP will detect 802.3at power during initial PoE negotiation vs doing it via LLDP. I don't feel this is a complete solution as I want LLDP to work. I will continue to work with HP to figure out why this command is needed.

Thank you,

You could also try to manually set the tx/rx chains in the CLI of the AP. I do not have an AP550 at my disposal today to compare results against.

CLI Commands:

radio profile <wifi1 radio profile name> transmit-chain <1-4>

radio profile <wifi1 radio profile name> receive-chain <1-4>

I have an AP250 though connected to an SR2208 switch and my show system power status shows AT.

What happens if you run the following command: system-power-mode 802.3at

I set the max to 30W and left LLDP on. I also tried LLDP off and no matter what the AP550 was still on AF power.

Interesting. The switch shows it as a class 4 device (.3at POE). But the AP shows it as .3af.

Can you hard set the max allowable power on the ethernet port to 30W? Thats the max for .3at POE - https://en.wikipedia.org/wiki/Power_over_Ethernet

Also if you got lldp enabled on the AP a show lldp nei should also confirm what we're seeing.

AP550 is plugged into port A2.

It doesn't look like you have LLDP enabled. Just put in the command "lldp" and hit enter. Wait ~60 seconds (LLDP exchanges info every 30 seconds) and do the show lldp neighbor command again.
