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.
3. Connect the other end of the ground cable to other device that has been grounded or directly to the terminal of the
ground bar in the equipment room.
Powering on the Switch
Notes:
• The GWN7816(P) uses a hot-swappable power supply unit to maintain the normal operation of the device.
• The PSU for GWN7816 comes with iron wire to prevent tripping.
• The PSU for GWN7816P comes with power cord anti-trip hole.
• In order to protect the stable power supply, it's recommended to fix the AC cable.
For GWN7816:
1. Rotate the iron wire counterclockwise, then insert the AC cable into the power socket.
2. Push the iron wire back until the power cord is secured.
For GWN7816P:
1. Place the smooth side of the fixing strap towards the power outlet and insert it into the hole on the side of it.
2. Connect the power cable and PSU1, then slide the protective rope over the fixed strap until the end of the power
cord and smoothly wrap the strap around the power cord and lock it tightly.
3. Plug the AC power cord into a power source such as a wall socket or power strip.
4. When you apply power, both the LED on the PSU and the switch's PSU1 indicator on the front panel that is
associated with the power supply light up. If these LEDs are not lit, make sure that the power cord is plugged in
correctly and the power source is good.

PORT CONNECTING
Connect to RJ45 Port
1. Connect one end of the network cable
to the switch, and the other end to the
peer device.
2. After powered on, check the status of the
port indicator. If on, it means that the link
is connected normally; if off, it means the
RJ45
link is disconnected, please check the
port
cable and the peer device whether is
enabled.
Connect to 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+ 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+ fiber module.
Insert one end of the fiber into the Rx and
Tx ports correspondingly, and connect the
other end to another device.
3. After powered on, check the status of the
port indicator. 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.
Connect to Console Port (DB9)
Notes:
• To connect, the steps order (1 -> 2) must be respected.
• To disconnect, the steps order is reversed (2 -> 1).
