LED Indicator Status Descriptions

Powering & Connecting

Grounding the Switch

1. Remove the ground screw from the back of the switch. Connect one end of the ground cable to the switch's wiring terminal.
2. Reinsert the ground screw and tighten it with a screwdriver.
3. Connect the other end of the ground cable to a device that is already grounded or directly to the ground bar in the equipment room. [Diagram description: Shows ground terminal, ground cable, and ground bar connection.]

Powering on the Switch

Connect the power cable to the switch first, then connect the power cable to the power supply system of the equipment room.

Connecting Power Cord Anti-Trip

To protect the power supply from accidental disconnection, it is recommended to use a power cord anti-trip for installation.

1. Place the smooth side of the fixing strap towards the power outlet and insert it into the hole on the side.
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. Ensure the power cord is securely fastened. [Diagram description: Illustrates the steps for attaching the power cord anti-trip.]

Port Connecting

Connect to RJ45 Port

1. Connect one end of the network cable to the switch's RJ45 port and the other end to the peer device. [Diagram description: Shows a PC connected to the switch via an RJ45 cable.]
2. After powering on, check the status of the port indicator. A solid green or flashing green light indicates a normal connection. If the indicator is off, the link is disconnected; check the cable and the peer device.

Connect to SFP+ Port

The installation process for the fiber module is as follows:

1. Grasp the fiber module and insert it smoothly into the switch's SFP+ port slot until it is in close contact with the switch. [Diagram description: Shows a fiber module being inserted into an SFP+ port on the switch.]
2. When connecting, ensure the Rx and Tx ports of the SFP fiber module are correctly aligned. Insert one end of the fiber into the corresponding Rx and Tx ports, and connect the other end to another device.
3. After powering on, check the port indicator status. A solid green or flashing green light indicates a normal connection. If the indicator is off, the link is disconnected; check the cable and the peer device.

Notes:

• Select the optical fiber cable according to the module type: multi-mode module requires multi-mode optical fiber, and single-mode module requires single-mode optical fiber.
• Use the same wavelength optical fiber cable for connection.

Please select an appropriate optical module according to actual networking requirements for different transmission distances. The laser in 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 to the DB9 male connector or USB port on the PC.
2. Connect the other end of the console cable (RJ45) to the switch's console port. [Diagram description: Shows console cable connections between a PC and the switch.]

Installation

Install on the Desktop

1. Place the bottom of the switch on a sufficiently large and stable table.
2. Peel off the protective paper from the four rubber footpads and stick them into the corresponding circular grooves at the four corners of the bottom of the case.
3. Flip the switch over and place it smoothly on the table. [Diagram description: Shows the switch with rubber footpads attached to the bottom.]

Install on the Wall

Note: For GWN7811, use the extended L-shaped rack-mounting kits included in the package.

1. Use the matching screws (KM 3*6) to fix the two L-shaped rack-mounting kits (rotated 90°) on both sides of the switch.
2. Position the switch with its ports facing up and horizontally on the selected wall. Mark the screw hole positions on the L-shaped rack-mounting kits with a marker. Drill holes at the marked positions using an impact drill and insert expansion screws (prepared by yourself) into the drilled holes in the wall.
3. Use a screwdriver to tighten the screws (prepared by yourself) that pass through the L-shaped rack-mounting kits to secure the expansion solenoids, ensuring the switch is firmly installed on the wall.

Install on a 19" Standard Rack

Note: For GWN7811, use the extended L-shaped rack-mounting kits included in the package.

1. Check the grounding and stability of the rack.
2. Install the two L-shaped rack-mounting kits on both sides of the switch using the provided screws (KM 3*6).
3. Place the switch in a proper position in the rack and support it by the bracket.
4. Fix the L-shaped rack-mounting kits to the guide grooves at both ends of the rack with screws (prepared by yourself) to ensure the switch is stably and horizontally installed on the rack. [Diagram description: Shows the switch being mounted in a 19-inch rack using L-shaped brackets.]

Access & Configure

Note: If no DHCP server is available, the GWN7811 default IP address is 192.168.0.254.

Method 1: Login using the Web UI

1. Connect a PC to any RJ45 port of the switch using a network cable.
2. Configure the PC's Ethernet (or local connection) IP address to 192.168.0.x (where 'x' is any value between 1-253) and the subnet mask to 255.255.255.0. This places the PC in the same network segment as the switch's IP address. This step can be skipped if DHCP is used.
3. Open a web browser and navigate to https://<GWN7811_IP>. Enter the default administrator username ("admin") and the default random password (found on the sticker on the GWN7811 switch) to log in. [Image description: A screenshot of the GWN7811 login page.]

Method 2: Login using the Console

1. Use the console cable to connect the switch's console port to the PC's serial port.

Method 3: Login Remotely using SSH/Telnet

1. Enable the Telnet function on the switch.
2. Open the Command Prompt (cmd) on your PC.
3. Enter telnet <GWN7811_IP> in the cmd window.
4. Log in using the default administrator username ("admin") and the default random password (found on the sticker on the GWN7811 switch).

Method 4: Configure using GWN.Cloud / GWN Manager

Navigate to https://www.gwn.cloud (or https://<gwn_manager_IP> for GWN Manager) in your browser. Log in with your account credentials. If you do not have an account, register first or ask your administrator to assign one.
