POWERING & CONNECTING
Grounding the Switch
- Remove the ground screw from the back of the switch, and connect one end of the ground cable to the wiring terminal of the switch.
- Put the ground screw back into the screw hole, and tighten it with a screwdriver.
- Connect the other end of the ground cable to the other device that has been grounded or directly to the terminal of the ground bar in the equipment room.
Powering on the Switch
- The GWN7816(P) uses a hot-swappable power supply unit to maintain the normal operation of the device.
- The PSU for GWN7816 comes with an iron wire to prevent tripping.
- The PSU for GWN7816P comes with a power cord anti-trip hole.
- In order to protect the stable power supply, it’s recommended to fix the AC cable.
For GWN7816
- Rotate the iron wire counterclockwise, then insert the AC cable into the power socket.
- Push the iron wire back until the power cord is secured.
For GWN7816P
- Place the smooth side of the fixing strap towards the power outlet and insert it into the hole on the side of it.
- Connect the power cable and PSU1, then slide the protective rope over the fixed strap until the end of the power cord, smoothly wrap the strap around the power cord, and lock it tightly.
- Plug the AC power cord into a power source such as a wall socket or power strip.
- 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
- Connect one end of the network cable to the switch, and the other end to the peer device.
- After powering 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.
Connect to SFP Port
The installation process of the fiber module is as follows:
- 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.
- When connecting, pay attention to confirming the Rx and Tx ports of the SFP+ fiber module. Insert one end of the fiber into the Rx and Tx ports correspondingly, and connect the other end to another device.
- After powering 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.
- 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 first-class laser products is harmful to the eyes. Do not look directly at the optical fiber connector.
Connect to the Console Port
- Connect the console cable (prepared by yourself) to the DB9 male connector or USB port to the PC.
- Connect the other end of the RJ45 end of the console cable to the console port of the switch.
- To connect, the steps order (1 -> 2) must be respected.
- To disconnect, the steps order is reversed (2 -> 1).
INSTALLATION
Install on the Desktop
- Place the bottom of the switch on a sufficiently large and stable table.
- Peel off the rubber protective paper of the four footpads one by one, and stick them in the corresponding circular grooves at the four corners of the bottom of the case.
- Flip the switch over and place it smoothly on the table.
Install on a 19” Standard Rack (Only for GWN7816)
- Check the grounding and stability of the rack.
- Install the two extended rack-mounting in the accessories on both sides of the switch, and fix them with the screws provided (KM 3*6).
- Place the switch in a proper position in the rack and support it with the bracket.
- Fix the extended rack mounting to the guide grooves at both ends of the rack with screws (prepared by yourself) to ensure that the switch is stable and horizontally installed on the rack.
Install on a 19” Cabinet (Only for GWN7816P)
GWN7816P can only be installed in cabinets with a spacing of 380mm-545mm between the front and rear hole bars.
- Install the two rear slideways supplied with the accessories on both sides of the switch, and fix them with the provided screws (KM 3*6).
- Based on the planned installation position of the switch on the cabinet, confirm and install the two rear rack-mounting kits at the appropriate positions on the rear hole strip with screws (prepared by yourself).
- Install the two front rack-mounting kits on both sides of the switch, and fix them with the provided screws (KM 3*6). Please refer to step 2 of GWN7816’s installation.
- Hold the switch and install it into the cabinet, embedding the slideways into the rear rack-mounting kits to ensure they support the switch. After adjusting to the appropriate position, use screws (prepared by yourself) to fix the front rack-mounting kits to the front hole strip, ensuring the switch is stable and horizontally installed on the cabinet.
To avoid high temperatures and keep the device cool, sufficient space should be left around the switch for heat dissipation. The air inlet of the switch cannot face or be close to the air outlet of other devices.
ACCESS & CONFIGURE
If no DHCP server is available, the GWN7816(P) default IP address is 192.168.0.254.
Method 1: Login using the Web UI
- A PC uses a network cable to correctly connect any RJ45 port of the switch.
- Set the Ethernet (or local connection) IP address of the PC to 192.168.0.x (“x” is any value between 1-253), and the subnet mask to 255.255.255.0, so that it is in the same network segment with the switch IP address. If DHCP is used, this step could be skipped.
- Type the switch’s management IP address https://<GWN7816(P)_IP> in the browser, and enter the username and password to log in. (The default administrator username is “admin” and the default random password can be found at the sticker on the GWN7816(P) switch).
Method 2: Login using the Console port
- Use the console cable to connect the console port of the switch and the serial port of the PC.
- Open the terminal emulation program of the PC (e.g. SecureCRT), and enter the default username and password to log in. (The default administrator username is “admin” and the default random password can be found at the sticker on the GWN7816(P) switch).
Method 3: Login Remotely using SSH/Telnet
- Turn on the Telnet of the switch.
- Enter “cmd” in PC/Start.
- Enter telnet <GWN7816(P)_IP> in the cmd window.
- Enter the default username and password to log in. (The default administrator username is “admin” and the default random password can be found at the sticker on the GWN7816(P) switch).
Method 4: Configure using GWN.Cloud / GWN Manager
Type https://www.gwn.cloud (https:// for GWN Manager) in the browser, and enter the account and password to log in to the cloud platform. If you don’t have an account, please register first or ask the administrator to assign one for you.
