Used EX4200-48T workes great but no POE
I am a Juniper ultra newbie. I wanted to dip my toes in the waters of doing things with VLANs and managed switches. I bought a used EX4200-48T from a IT surplus hardware place.
I would like to use it to replace some of the household network gear I have in my basement. I have a little bit of Ubiquiti APs and cameras that I would love to use on the 8 POE ports on the switch.
The POE ports appear to be configured as they should:
root@juniper> show poe interface
Interface Admin Oper Max Priority Power Class
status status power consumption
ge-0/0/0 Enabled OFF 15.4W Low 0.0W not-applicable
ge-0/0/1 Enabled OFF 15.4W Low 0.0W not-applicable
ge-0/0/2 Enabled OFF 15.4W Low 0.0W not-applicable
ge-0/0/3 Enabled OFF 15.4W Low 0.0W not-applicable
ge-0/0/4 Enabled OFF 15.4W Low 0.0W not-applicable
ge-0/0/5 Enabled OFF 15.4W Low 0.0W not-applicable
ge-0/0/6 Enabled OFF 15.4W Low 0.0W not-applicable
ge-0/0/7 Enabled OFF 15.4W Low 0.0W not-applicable
root@juniper> show poe controller
Controller Maximum Power Guard Management Status Lldp
index power consumption band Priority
0 130.00W 0.00W 0W Class AF_ENHANCE Disabled
If I connect any POE device to it they do not get any power. If I connect non-POE devices like a laptop to them they work as normal LAN ports, which is what I expected.
I've tried the various setup commands and still nothing. I do not know if it is just thet the Ubiquiti APs and cameras just don't support the style of POE that the EX4200 is using or if something is wrong with the switch.
Here are some more data dumps from some config commands:

Also the power supply is reporting AC and DC as "OK".
Even if I can't use the POE it won't be a huge deal as that was more of a nice to have. If there is anything I can do to get it working though I would love to try.
