Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
c2960x-48fpd-l-0(config)#int gi1/0/1
c2960x-48fpd-l-0(config-if)#power inline port 2x-mode
c2960x-48fpd-l-0(config-if)#shutdown
c2960x-48fpd-l-0(config-if)#no shutdown
power inline port priority high
power inline static max 15400
To resolve the issue, temporaritly, I log in to the stack via SSH and run the below:
configure
interface Gi1/0/23
power inline reset
This resets the port and powers on the AP again.
I had also set the below parameters on each port range where the APs are connected
power inline high-power (i think this is equivalent to 2x-mode in cisco)
power inline limit none
power inline priority critical
