Frequently Asked Questions - GS-105A ZYXEL

How to install the ZYXEL GS-105A switch?

Place the switch on a flat and stable surface near a power outlet. Connect the included power adapter to the back of the switch and then to the outlet. Connect your network devices to the Ethernet ports using RJ-45 cables. The PWR LED should light up green.

What do the LED indicators on the GS-105A mean?

The PWR green LED indicates the switch is powered on. 100/1000 green = 1000 Mbps, orange = 100 Mbps, off = 10 Mbps or no connection. LNK/ACT green = link established, blinking = activity. FDX/COL orange = full-duplex mode, blinking = collision.

Can I use a crossover or straight-through cable?

Yes, the GS-105A ports are auto-MDI/MDIX, allowing you to use either a straight-through or crossover cable to connect a computer, hub, or another switch.

What type of Ethernet cable is recommended?

For optimal Gigabit (1000 Mbps) performance, use a UTP/STP Category 5 or higher cable with 4 pairs. The maximum length is 100 meters.

The switch does not power on, what should I do?

Check that the power adapter is properly connected to the switch and a working outlet. Try another outlet. If the PWR LED remains off, the adapter may be defective; contact ZyXEL support.

How to clean the switch?

Disconnect the device before cleaning. Use a dry, soft cloth to wipe the surface. Do not use chemicals or liquids.

Is the GS-105A compatible with rack mounting?

No, the GS-105A is designed for desktop use. It is not supplied with a rack mount kit.

What is the warranty of the GS-105A?

ZyXEL offers a limited 2-year warranty from the purchase date against defects in materials and workmanship. Keep your proof of purchase.

Can I connect the switch to another switch?

Yes, you can cascade multiple switches by connecting one port of one to a port of another. Use a standard Ethernet cable. The switch will automatically detect the speed.

The LNK/ACT LED blinks rapidly, is this normal?

Yes, the blinking of the LNK/ACT LED indicates data being transmitted or received on that port. This is normal behavior during network activity.

Getting to Know Your Switch

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.

Standalone Workgroup Application

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

Standalone Workgroup Example

Hardware Installation and Connection

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

Desktop Installation

Step 1. Make sure the switch is clean and dry.

Step 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.

Step 3. Use the supplied power adapter 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.

Rear Panel 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.

Port Connection

For GS-105, the Ethernet ports are located on the rear panel. For GS-108, the Ethernet ports are located on the front panel.

RJ-45 Auto-negotiating Ports

Your 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.

Auto-sensing (MDI/MDIX) Ethernet Ports

Each Ethernet port allows you to connect to a computer or to a hub using either a straight-through or a crossover Ethernet cable.

The following table describes the types of network cable used for the different connection speeds.

Table 1 Ethernet Cable Type

SPEED	NETWORK CABLE TYPE
10 Base-T	100 2-pair UTP/STP Category 3, 4 or 5
100 Base-TX	100 2-pair UTP/STP Category 5
1000 Base-T	100 4-pair UTP/STP Category 5

Cable length between connections must not exceed 100 meters (328 feet).

Front Panel LEDs

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