I purchased a new WAP571-A-K9 V01 which is having issues with PoE. When I connect the WAP to our new Aruba 2920-48G-PoE+ switch on port 3/17, I receive the following error when logging into the web console for the WAP:
The power source of WAP device is using IEEE 802.3af PoE standard provides. The device will run in lower CPU frequency and turn off ETH1 Ethernet port, the wireless will also use 2 antennas to transmit & receive data. It is highly recommended using IEEE 802.3at Power Source Equipment (PSE) to get the best performance. If the required power by the WAP device exceeds the maximum power delivered by the PSE, then the WAP device may reboot.
Under the System Summary for the device, it states that the Power Source is 802.3af PoE.
When I run the command "show power-over-Ethernet 3/17" I receive this output:
Status and Counters - Port Power Status for port 3/17
Power Enable : Yes
LLDP Detect : enabled
Priority : low Configured Type :
AllocateBy : usage Value : 17 W
Power Class : 4 Detection Status : Delivering
Over Current Cnt : 0 MPS Absent Cnt : 4
Power Denied Cnt : 0 Short Cnt : 0
Voltage : 56.6 V Current : 144 mA
Power : 8.1 W Pre-std Detect : off
The device shipped with the 1.0.0.14 firmware which was experiencing the above issue. Even after upgrading to 1.0.0.17, the problem still persists.
Its worth noting that I have some PoE 802.3af phones connected to the switch as well. Running the command "show power-over-Ethernet 1/3" on one of the switch ports where I've connected a phone yields these results:
Status and Counters - Port Power Status for port 1/3
Power Enable : Yes
LLDP Detect : enabled
Priority : low Configured Type :
AllocateBy : usage Value : 17 W
Power Class : 2 Detection Status : Delivering

Power Denied Cnt : 0 Short Cnt : 0
Voltage : 56.3 V Current : 56 mA
Power : 3.1 W Pre-std Detect : off
I want to make sure that the device is running at full power but I have a hunch that the WAP571 is incorrectly detecting PoE+ on my Aruba switch. Can anybody shed some light on this?
Thanks!
