POWERING & CONNECTING
Grounding the Switch
1. Remove the ground screw from the back of
switch, and connect one end of the ground
cable to the wiring terminal of switch.
2. Put the ground screw back into the screw hole,
and tighten it with a screwdriver.

to other device that has been grounded or
directly to the terminal of the ground bar in the
equipment room.
Powering on the Switch
Connect the power cable and the switch first,
then connect the power cable to the power supply
system of the equipment room.
Connecting Power Cord Anti-Trip
In order to protect the power supply from
accidental disconnection, it's recommended to
use a power cord anti-trip for installation.
1. Force the head of the fixing strap tightly into
the hole next to the power socket until it's
buckled on the shell without falling off.
2. After plugging the power cord into the power
outlet, slide the protector over the remaining
strap until it slides over the end of the power
cord.
3. Wrap the strap of the protective cord around
the power cord and lock it tightly. Fasten
the straps until the power cord is securely
fastened.

Connect to SFP/SFP+ Port
The installation process of the fiber module is as follows:
1. Grasp the fiber module from the side and insert it
smoothly along the switch SFP/SFP+ port slot until the
module is in close contact with the switch.
2. When connecting, pay attention to confirm the Rx and
Tx ports of SFP/SFP+ fiber module. Insert one end of
the fiber into the Rx and Tx ports correspondingly, and
connect the other end to another device.

If on, it means that the link is connected normally; if
off, it means the link is disconnected, please check the
cable and the peer device whether is enabled.
Notes:
• Please select the optical fiber cable according to the module type. The multi-mode module corresponds to the
multi-mode optical fiber, and the single-mode module corresponds to the single-mode optical fiber.
• Please select the same wavelength optical fiber cable for connection.
• Please select an appropriate optical module according to the actual networking situation to meet different
transmission distance requirements.
• The laser of the first-class laser products is harmful to eyes. Do not look directly at the optical fiber connector.
Connect to Console Port
1. Connect the console cable (prepared by yourself) to the DB9 male connector or USB port to the PC.
2. Connect the other end of the RJ45 end of the console cable to the console port of switch.
