Step 1. Identify the PoE switch in the telecommunication rack.
A PoE switch is a device that gives power to cameras and connects them to the network. Look for a gray box with Ethernet cables and one power supply connected.
Step 2. Identify cable status LEDs and their color.
In the example above:
Port 1 Cable status LEDs: Two green LEDs (left LED blinking and right LED static on)
Port 2 Cable status LEDs: Left green LED on
Step 3. Unplug power cable from the switch.
Unplug the power cable, wait 1 minute, and plug it back in.
