Frequently Asked Questions - ES2108G ZYXEL

How to install the ES2108G switch on a desk?

Place the switch on a flat, stable surface. If rubber feet are provided, attach them to the bottom corners to prevent vibration. Ensure at least 10 cm of ventilation in front and 8 cm behind the device.

Can I mount the switch in a rack?

Yes, the switch comes with brackets and screws for EIA standard rack mounting. Attach the brackets to the sides of the switch, then screw the assembly into the rack using the appropriate holes.

What types of network cables to use?

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) Ethernet cables of category 5e or higher. For 1000 Mbps connections, a category 5e cable with 4 pairs is required. Maximum length is 100 meters.

What does the LNK/ACT LED mean?

The LNK/ACT LED lights up green when a device is connected and the link is established. It blinks when there is network activity (data transmission). If it does not light up, check the connection and the state of the connected device.

How to connect the power supply?

Plug the provided power adapter into the power inlet of the switch, then into an electrical outlet. The PWR LED should light up. If not, check the outlet and adapter.

Can I use a crossover or straight-through cable?

The ports of the ES2108G switch support auto-crossover (Auto MDI/MDI-X). Therefore, you can use either a straight-through or crossover cable to connect any type of device (computer, router, other switch).

What to do if no LED lights up?

Check that the power adapter is properly connected on both sides and that the electrical outlet works. If the problem persists, contact your dealer or ZYXEL support.

How to clean the switch?

First, disconnect the power. Use a soft, dry cloth to wipe the casing. Do not use liquids, solvents, or abrasive products.

What are the safety precautions?

Install the switch on a stable, well-ventilated surface. Do not block the ventilation openings. Use only the provided power adapter. Avoid extreme temperatures and humidity.

Can I repair the switch myself?

The switch contains no user-serviceable parts. Do not open it. In case of malfunction, contact ZYXEL technical support or an authorized professional.

USER MANUAL ES2108G ZYXEL

This Quick Start Guide is for use with all ZyXEL Ethernet switches. Your device may differ from the illustrations below.

2 Installation

All switches can be used as a standalone device while some can alternatively be mounted on standard EIA racks.

Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the switch. Leave space between switches if stacking.

2.1 Desktop Installation

1 Set the switch on a smooth, level surface.
2 If your switch comes with unattached rubber feet, attach them to each corner on the bottom of the switch. These

ENGLISH

rubber feet help protect the switch from shock or vibration and ensure space between devices when stacking.

2.2 Rack-mounted Installation

1 Align one bracket with the holes on one side of the switch and secure it with bracket screws smaller than the rackmounting screws. Similarly, attach the other bracket.

2 After attaching both mounting brackets, position the switch in the rack by lining up the holes in the brackets with the

appropriate holes on the rack. Secure the switch to the rack with the rack-mounting screws.

3 Hardware Connections

3.1 Auto-negotiating and Auto-crossover RJ-45 ports

Your switch comes with auto-negotiating, auto-crossover ports. Depending on the model, these ports are either fast Ethernet (10/100 Mbps) or Gigabit (10/100/1000 Mbps) ports. Auto-negotiating ports can detect the speed of incoming transmissions and allow either half duplex transfer mode (10/100 Mbps only) or full duplex mode. Auto-crossover means that you can connect the switch to a computer or hub using either a straight-through or a crossover Ethernet cable.

3.2 Network Cables

You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet cables for RJ-45 ports. Make sure the cable length between connections does not exceed 100 meters (328 feet). The following table describes the types of network cable used for different connection speeds.

Table 1 Network Cable Types

SPEED	NETWORK CABLE TYPE
10Mbps	100 Ω 2-pair UTP/STP Category 3,4 or 5
100Mbps	100 Ω 2-pair UTP/STP Category 5
1000Mbps	100 Ω 4-pair UTP/STP Category 5

The LNK/ACT LED should flash when data is being sent between your switch and a connected device.

3.3 Power Connection

Connect one end of the supplied power cable or power adaptor to the power receptacle on the switch and the other end to the appropriate power source. The PWR LED should turn steady on if the switch is receiving power.

3.4 Console Port (Managed Switches Only)

If your switch has a console port, you can use a terminal emulator for local management. Connect the male 9-pin end of a console cable to the console port of the switch. Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer. Configure the computer with terminal emulation software to the following parameters:

• VT100 terminal emulation
  9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control

4 Troubleshooting

PROBLEM	CORRECTIVE ACTION
None of the LEDs are on when the power is connected.	Verify that the included power or cable adaptor is connected to the switch's power receptacle and appropriate power source. If the error persists, you may have a hardware problem and should contact your vendor.
The LNK/ACT LED does not light up or flash when a device is connected.	Verify that the attached device(s) is turned on and properly connected to your switch. Also make sure the Ethernet cards are working on the attached devices. Verify that the network cable does not exceed 100 meters.
