a port in SW 1910 shutdown after plugin a cable from fingerprint

hi all,

I have an HPE SW 1910-48G working normally until today. After I plugged an RJ45 cable to connect my fingerprint device (use 1 2 3 6 cable only) into port 48 => the port is shut down and disabled till now  (when I connect it to another device it does now turn on the light and nothing happen) 

When I check in the Interface Statistic, it showed that port 48 is InDiscards and InErrors. The same thing happened to another port in another SW when I try to test the cable connected with the fingerprint.

Is there any solution to restore the port? Is that a problem with the electric shock go through RJ45? But my SWs is not a POE...

Thanks much.
