Connecting AC Power Cable
AC power socket (recommended)
You are recommended to use a mono-phase three-core power socket with a neutral point or a
multi-function power socket for computers. The neutral point of the power in your building must be well
grounded. Normally, the neutral point of the power supply system in your building has already been
grounded during the construction and wiring; but you should make sure this is the fact.

Connecting AC power cable
1) Connect one end of the grounding cable (delivered with the switch) to the grounding screw on the
rear of the chassis and the other end to the ground nearby.
2) Connect one end of the power cable to the power socket on the rear panel of the chassis and the
other end to an outside AC power socket.
3) Install the power cord retainer for the AC power cord on S3100-TP-PWR-EI series Ethernet
Switches. Insert the two ends of the power cord retainer into the slots at both sides of the AC power
input, and then set the power cord into the notch of the power cord retainer, as shown in
Figure
