Power cycle PoE port killed my switch :/

Hi.

I use this plugin for my APs and today I tried to power cycle a port on my unifi switch US-8-60w. The power turned off but now none of my PoE-ports is giving power and I cant turn them on.
I have tried to use power ON to no avail.
PoE injector still works so it's a switch problem.
I cant find a setting in the Unifi GUI to power on the ports again and "#show poe status all" shows

Code: Select all
Intf      Detection      Class   Consumed(W) Voltage(V) Current(mA) Temperature(C)
--------- -------------- ------- ----------- ---------- ----------- --------------
0/5       Open Circuit   Unknown        0.00       0.00        0.00             53
0/6       R Sig Too Low  Unknown        0.00       0.00        0.00             53
0/7       Open Circuit   Unknown        0.00       0.00        0.00             53
0/8       Open Circuit   Unknown        0.00       0.00        0.00             53


0/5 is where my camera is connected
0/6 is an turned off TV, no PoE.

I have factory reset the switch to no avail.

What has happened???

at the unifi controller:
1. go to devices
2. click on the switch
3. click on ports
4. click on "profile overrides>"
you should then see this:.

there try POE off/ on


The plugin POE cycle command does the following:
ssh to the switch and login
Code: Select all
telnet localhost 23
enable
configure
interface 0/<<PORT# here>>
poe opmode shutdown
poe opmode auto
exit
exit
exit
exit
exit

Must have been a coincident that my cable decided to fail exactly when I tested the "cycle PoE power" function :) There was a half bad connection that fooled the switch there was nothing connected but my dumb PoE-injector w/o auto sensing worked. After fixing the cable it now works.
