These are the steps you need to take to ensure that the key fob system is reset.
Unplug the Ethernet cable from the back of the reader and leave it disconnected for 10–15 minutes, then reconnect it.
Also unplug and reconnect the Ethernet cable at the switch end.
Check the switch port and confirm whether the Ethernet link/activity (Green good ethernet, red bad) LEDs are lit.
If possible, test the reader using a known-working CAT6 Ethernet cable and a different PoE+ switch port
If there is no network activity on the switch port, please check with your network administrator or ISP to ensure the port is active and passing traffic.
