Is temperature sensor on zero enough to prove PoE Control Module is failed?

Dell PowerConnect 5548P no power to Ubiquiti ER-X
Ubiquiti is very loose with the term PoE.

PowerConnect 5500 Series VLAN routing problem
VLAN 1 is the flat 192.168.69.0/24 VLAN 10 is 192.168.0.0/16
192.168.69.0/24 is a subnet of 192.168.0.0/16, making your routing ambiguous. You'll need to separate that properly, ie. without overlap.
