Correct ACL rules to isolate WiFi traffic from other VLANs?

Is temperature sensor on zero enough to prove PoE Control Module is failed?
(converted from comments)
The "Total Power" figure should show what the PSU can deliver, regardless of what's currently in use. The "0 W" pretty clearly shows there's something wrong.
Possibly, the ...

Stacking Pair of Dell PC2724 Switches

Dell PowerConnect 5548P no power to Ubiquiti ER-X

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.

The only thing that I have spotted at the moment is that you have no default route. Currently you have traffic only destined to x.x.8.164/30 routed out of VLAN 4010.
