TRENDNet 8 Port POE Switch [PB02]

What is it?
The TrendNet 8 Port POE switch allows up to 8 CAT connections to talk to each other. Up to 4 of those CAT connections can receive POE (Power Over Ethernet) and receive their power over the CAT cable as opposed to a second cable to a wall outlet

How if functions in our network?
This switch acts as the main "Trunk" switch. It can access all networks & powers the Cisco AP PW02 using POE. It also connects the 2 CAT cables running to SL and SR, where SR has the TP-Link AP PW03, but PW03 does not receive POE

Troubleshooting
Check to see if PW02 has a blinking light, if so POE is working and the switch has power. Otherwise it may not be plugged in or be broken. Verify the PWO2 is in a POE port on PB02.
Note: If PW02 has a blue light, then you know your connection is working and it likely isn't a switch issue
