[Optional Product] Please tell me how to use the POE switch of the high-speed communication line unit F-130814 series.

The POE switch is used to avoid communication errors caused by resonance with the CDN during POE communication between the EUT and AE.
When the switch is turned ON (green lamp lights up), the decoupling circuit is disconnected.
Therefore, during testing, the test must be conducted with the decoupling circuit connected (switch OFF: green lamp off).
To avoid resonance, turn on the POE switch first, then turn on the power to the EUT and AE. After confirming communication, be sure to turn OFF the POE switch before surge output, then conduct the test.
