Connect a PC to the console port of the switch using the provided console cable. Configure the PC's serial port with the following parameters: 38400 bps, 8 data bits, no parity, 1 stop bit, no flow control. Log in to the CLI with the username 'admin' and the password 'admin'.

What is the default IP address of the GTL5291 switch?

The default IP address for web interface management is 192.168.1.1. Make sure your computer is on the same subnet (e.g., 192.168.1.2 to 192.168.1.250).

What are the default login credentials?

The default username is 'admin' and the default password is 'admin'. It is strongly recommended to change them after the first login.

How to mount the switch in a rack?

Attach the provided L-shaped brackets to the sides of the switch using the screws. Place the switch in the rack and secure the brackets to the guide slots using screws. Ensure the rack is stable and properly grounded.

Can the switch be installed on a table?

Yes, place the switch on a stable and sufficiently large worktable with the base facing up, then flip it over. Ensure the table is properly grounded and the device is stable.

What are the environmental requirements for operation?

The switch must be installed indoors away from direct sunlight, heat sources, and strong electromagnetic interference. Ambient temperature should be between -10 °C and 50 °C and relative humidity between 10% and 90% (non-condensing).

How to configure my computer's IP address to access the web interface?

On Windows, go to Control Panel > Network and Sharing Center > Change adapter settings. Right-click on Local Area Connection > Properties. Double-click on Internet Protocol Version 4 (TCP/IPv4) and set a static IP address between 192.168.1.2 and 192.168.1.250 with a subnet mask of 255.255.255.0.

What to do if the power LED does not light up?

Check that the power cord is properly connected to the switch and to a working power outlet. Ensure the voltage matches 100-240 V AC 50/60 Hz. If the problem persists, contact technical support.

How to reset the switch to factory defaults?

The reset procedure is not described in the manual. Refer to the Web Management Guide or CLI Reference Guide for instructions. Generally, a reset button or a CLI command can restore default settings.

Can I use SFP modules with this switch?

Equipment Installation

1. Installed in the rack

Install the switch on a 19-inch standard rack, and the installation steps are as follows:

• Check the grounding and stability of the rack;
• Install the two L-shaped brackets in the accessories on both sides of the switch panel, and fix them with the screws in the accessories;
• Place the switch in the appropriate location of the rack, and support it using a tray;
• Secure the L-shaped brackets on the guide slots fixed at both ends of the rack, to ensure that the switch can be mounted on the rack in astable, horizontal manner;
• Use a power cord to connect the switch power connector with the powersocket.

2. Installed on the working table

Install the switch on a working table, and the installation steps are as follows:

• Place the switch with its bottom up on a sufficiently large, stable and properly-grounded working table;
• Flip over the switch, and place it on the working tablestably;
• Use a power cord to connect the switch power connector with the power socket.
• The switch uses 100-240V, 50/60Hz AC, and make sure that both power supply and grounding are normal before power on.
• After power on, please check the switch's power indicator (Power) is on, and if so, it indicates that the power supply is connected properly.
• Do not place heavy objects on the top of the switch.
