4.1 Connecting GND
GND cables do not come with the package of select models. Purchase them as needed.
Grounding the Switch can protect it against lightning and interference. The steps for connecting the
GND are as follows:
Step 1
Remove the ground screw from the Switch and pass the ground screw through the round
hole of the OT terminal of the ground cable. Turn the ground screw clockwise with a cross
screwdriver to fasten the OT terminal of the ground cable.
Step 2
Wind the other end of the ground cable into a circle with the needle-nose pliers.
Step 3
Connect the other end of the ground cable to the ground bar, then turn the hex nut
clockwise with a wrench to fasten the other end of the ground cable to the ground
terminal.

4.2 Connecting Power Cord
Before connecting the power cord, make sure that the Switch is securely grounded.
Step 1
Connect one end of the power cord to the power jack of the Switch.
Step 2
Connect the other end of the power cord to the external power socket.
4.3 Connecting SFP Ethernet Port
Step 1
We recommend wearing antistatic gloves, and then the anti-static wrist strap before
installing SFP module. Make sure that the anti-static wrist strap and the antistatic gloves
are in good contact.
Step 2
Lift the handle of the SFP module upward vertically, and stick it to the top hook. Hold the
SFP module by both sides, and push it gently into the SFP slot till the SFP module is firmly
connected to the slot (You can feel that both the top and bottom spring strip of the SFP
module are firmly stuck with the SFP slot).
