Currently, only the S3100-TP-PWR-EI series Ethernet Switches are equipped with an AC power
cord retainer to prevent the power cord from accidentally falling off.

The location of the power cord retainer holder varies with S3100-TP-PWR-EI series Ethernet
Switches.
4) Check whether the PWR LED on the front panel of the switch is ON. If yes, the power is properly
connected.
Before powering on the switch, you should properly connect the grounding cable.
