Frequently Asked Questions - ES-3124 ZYXEL

How to install the ZYXEL ES-3124 switch on a desk?

Place the switch on a flat surface. If feet are provided, attach them to the corners to dampen vibrations and ensure spacing if stacking.

How to mount the switch in a 19-inch rack?

Attach the provided brackets to the sides of the switch with the smaller screws. Insert the switch into the rack and secure it with the provided mounting screws.

What types of network cables can I use?

Use UTP or STP Ethernet cables. For 10/100 Mbps, Category 3/4/5 is sufficient. For 1000 Mbps, use Category 5 or higher cables. Maximum length is 100 meters.

Does the switch automatically detect cable type (straight or crossover)?

Yes, the ports are auto-MDI/MDI-X. You can connect a computer or hub with either a straight or crossover cable.

How to connect the power supply of the switch?

Connect the provided power adapter to the switch's power jack, then plug it into a wall outlet. The PWR LED should light up.

What to do if the LNK/ACT LED does not light up when a device is connected?

Check that the connected device is powered on and the cable is properly plugged in. Ensure the device's network card is working and the cable does not exceed 100 meters.

How to use the console port of the switch?

Connect a serial console cable (RJ-45 or DB9) between the switch and a serial port on your computer. Use a terminal emulator (VT100) configured at 9600 bps, 8 data bits, no parity, 1 stop bit, no flow control.

No LEDs light up when power is connected. What to do?

Check that the power adapter is properly connected to the switch and the electrical outlet. If the problem persists, the hardware may be defective; contact your reseller.

How much space to leave around the switch for ventilation?

Leave at least 10 cm in front and 8 cm behind the switch. If stacking multiple switches, space them adequately.

Does the switch support Gigabit Ethernet?

Yes, depending on the model, ports can be Fast Ethernet (10/100 Mbps) or Gigabit (10/100/1000 Mbps). Check your device specifications. Ports support auto-negotiation.

USER MANUAL ES-3124 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.
