Frequently Asked Questions - GS-108B ZYXEL

How to connect the power supply of the GS-108B switch?

Connect the supplied AC adapter (12V DC / 1A) to the power port on the back of the switch, then plug it into an electrical outlet. The PWR LED lights up green.

What types of cables to use for the Ethernet ports?

All ports are Auto-MDIX, so you can use either a straight-through or crossover cable. For Gigabit connection, use a Category 5 or higher UTP/STP cable with 4 pairs.

How to interpret the LED indicators on the front panel?

The green PWR LED indicates the switch is powered on. For each port, a solid green LNK/ACT LED means a link is established, and blinking indicates network activity (data transmission/reception).

What is the maximum transfer speed of the GS-108B?

Each port supports up to 1000 Mbps (1 Gbps) in full-duplex. The maximum forwarding rate is 1,488,000 packets per second for 1000 Mbps mode.

Can I use the switch with 10/100 Mbps devices?

Yes, the GS-108B is backward compatible. The ports perform auto-negotiation to adapt to the speed of the connected device (10, 100, or 1000 Mbps) and duplex mode.

What is the recommended ambient temperature for operation?

The switch can operate in a temperature range between 0°C and 40°C. Avoid exposing it to extreme temperatures or direct sunlight.

How many MAC addresses can the GS-108B handle?

The MAC address table can store up to 8,000 entries (8K), allowing it to manage a large number of devices on the network.

How to clean the switch?

Unplug the power before cleaning. Use a soft, dry cloth to wipe the surface. Never use liquids, aerosols, or abrasive products.

Is the switch compatible with copper cables?

Yes, all ports are copper RJ-45. For a maximum distance of 100 meters, use appropriate category UTP/STP cables.

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

Check that the AC adapter is properly connected to the switch and to a working outlet. Try a different power cable if possible. If the problem persists, contact technical support.

1 Introduction

The switch is a multi-port switch that can be used to build high-performance switched networks. The switch is a store-and-forward device that offers low latency for high-speed networking. The switch is designed for SOHO (Small Office Home Office) businesses.

The switch can be used as a standalone switch to which computers, servers and print server are directly connected to form a small workgroup.

2 Hardware Installation

The switch is suitable for an office environment where it can be placed on a desktop.

1 Make sure the switch is clean and dry.
2 Set the switch on a smooth, level flat space strong enough to support the weight of the switch and the connected cables. Make sure there is a power outlet nearby.
3 Use only the supplied power adaptor to connect your switch to a power source. Refer to the label on the power adapter for more information.

Do not block the ventilation holes.

3 Hardware Connection

The power and the Ethernet ports are located on the rear panel.

3.1 Power Connection

Connect one end of the supplied power adaptor to the power port on the rear panel of the switch and the other end to the appropriate power source. The PWR LED turns on.

3.2 RJ-45 Auto-negotiating Ports

The switch comes with 5 or 8 10/100/1000M RJ-45 ports depending on the model of your switch. The auto-negotiation feature allows the switch to detect the speed of incoming transmission and adjust appropriately without manual intervention. It allows data transfers of 10 Mbps, 100 Mbps or 1000 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.

3.3 Auto-crossover Ethernet Ports

All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so you may use either a straight-through Ethernet cable or crossover Ethernet cable for all Ethernet port connections. Autocrossover ports automatically sense whether they need to function as crossover or straight ports, so crossover cables can connect both computers and switches/hubs.

Refer to the Product Specifications section for the types of network cable used for the different connection speeds.

3.4 Front Panel LEDs

The LEDs on the front panel indicate the real-time status of the switch.

LED	COLOR	STATUS	DESCRIPTION
PWR	Green	On	The switch is on and receiving power.
		Off	The switch is not receiving power.
LNK/ACT	Green	On	The port is connected to an Ethernet network.
		Blinking	The port is receiving or transmitting data.
		Off	The port is not connected to an Ethernet network.
