Getting to Know Your Switch

1.1 Introduction

This chapter introduces the main features and applications of the Switch. The GS1920 Series consist of the four following models:

•GS1920-24

•GS1920-24HP

•GS1920-48

•GS1920-48HP

Referring to PoE model(s) in this User's Guide only applies for GS1920-24HP and GS1920-48HP.

The Switch is a layer-2 standalone Ethernet switch with additional layer-2, layer-3, and layer-4 features suitable for Ethernets.

With its built-in web configurator, including the ZyXEL One Network (ZON) Neighbor Management feature (Section 7.3 on page 53), viewing, managing and configuring the Switch and its neighboring devices is easy. The Switch can also be managed via third-party SNMP management.

In addition, ZyXEL offers a proprietary software program called ZyXEL One Network (ZON) Utility, it is a utility tool that assists you to set up and maintain network devices in a more simple and efficient way. You can download the ZON Utility at www.zyxel.com and install it on a PC. For more information on ZON Utility see (Section 7.2 on page 52).

The following table describes the port features of the Switch by model.

Table 1 Models and Port Features

SWITCH MODEL	PORT FEATURES
GS1920-24 and GS1920-	• 24 10/100/1000 Mbps Ethernet ports
24HP	• 4	GbE dual personality interfaces

GS1920-48 and GS1920-	• 44 10/100/1000 Mbps Ethernet ports
48HP	• 4	GbE dual personality interfaces
	• 2	SFP interfaces

The GS1920-48HP comes with a Power-over-Ethernet (PoE) feature. The GS1920-48HP supports the IEEE 802.3at High Power over Ethernet (PoE) standard and IEEE 802.3af PoE standard.

Key feature differences between Switch models are as follows. Other features are common to all models.

This section shows a few examples of using the Switch in various network environments.

1.1.1 Backbone Application

The Switch is an ideal solution for small networks where rapid growth can be expected in the near future. The Switch can be used standalone for a group of heavy traffic users. You can connect computers and servers directly to the Switch’s port or connect other switches to the Switch.

In this example, all computers can share high-speed applications on the server. To expand the network, simply add more networking devices such as switches, routers, computers, print servers etc.

Figure 1 Backbone Application

1.1.2 Bridging Example

In this example, the Switch connects different company departments (RD and Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users that need high bandwidth can connect to high-speed department servers via the Switch. You can provide a super-fast uplink connection by using a Gigabit Ethernet/mini-GBIC port on the Switch.

Moreover, the Switch eases supervision and maintenance by allowing network managers to centralize multiple servers at a single location.

GS1920 Series User’s Guide

Chapter 1 Getting to Know Your Switch

Figure 2 Bridging Application

1.1.3 High Performance Switching Example

The Switch is ideal for connecting two networks that need high bandwidth. In the following example, use trunking to connect these two networks.

Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance. The Switch can provide the same bandwidth as ATM at much lower cost while still being able to use existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely communicate with each other.

Figure 3 High Performance Switched Workgroup Application

1.1.4 IEEE 802.1Q VLAN Application Examples

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through a router.

For more information on VLANs, refer to Chapter 9 on page 85.

GS1920 Series User’s Guide

Chapter 1 Getting to Know Your Switch

1.1.4.1 Tag-based VLAN Example

Ports in the same VLAN group share the same frame broadcast domain thus increase network performance through reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re-cabling.

Shared resources such as a server can be used by all ports in the same VLAN as the server. In the following figure only ports that need access to the server need to be part of VLAN 1. Ports can belong to other VLAN groups too.

Figure 4 Shared Server Using VLAN Example

1.2 Ways to Manage the Switch

Use any of the following methods to manage the Switch.

•Web Configurator. This is recommended for everyday management of the Switch using a (supported) web browser. See Chapter 4 on page 33.

•FTP. Use FTP for firmware upgrades and configuration backup/restore. See Section 37.7.1 on page 305.

•SNMP. The Switch can be monitored by an SNMP manager. See Section 38.5 on page 315.

•Cluster Management. Cluster Management allows you to manage multiple switches through one switch, called the cluster manager. See Chapter 41 on page 331.

1.3Good Habits for Managing the Switch

Do the following things regularly to make the Switch more secure and to manage the Switch more effectively.

•Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.

•Write down the password and put it in a safe place.

GS1920 Series User’s Guide

Chapter 1 Getting to Know Your Switch

•Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Switch. You could simply restore your last configuration. See Section 3.4 on page 30 for how to reset the Switch.

GS1920 Series User’s Guide

Hardware Installation and Connection

2.1 Installation Scenarios

This chapter shows you how to install and connect the Switch.

The Switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop installation and the brackets in a rack-mounted installation.

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. This is especially important for enclosed rack installations.

2.2 Desktop Installation Procedure

1Make sure the Switch is clean and dry.

2Set the Switch on a smooth, level surface strong enough to support the weight of the Switch and the connected cables. Make sure there is a power outlet nearby.

3Make sure there is enough clearance around the Switch to allow air circulation and the attachment of cables and the power cord.

2.3Mounting the Switch on a Rack

The Switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your Switch on a standard EIA rack using a rackmounting kit.

2.3.1Rack-mounted Installation Requirements

•Two mounting brackets.

•Eight M3 flat head screws and a #2 Philips screwdriver.

•Four M5 flat head screws and a #2 Philips screwdriver.

Failure to use the proper screws may damage the unit.

2.3.1.1Precautions

•Make sure the rack will safely support the combined weight of all the equipment it contains.

GS1920 Series User’s Guide

Chapter 2 Hardware Installation and Connection

•Make sure the position of the Switch does not make the rack unstable or top-heavy. Take all necessary precautions to anchor the rack securely before installing the unit.

2.3.2Attaching the Mounting Brackets to the Switch

1Position a mounting bracket on one side of the Switch, lining up the four screw holes on the bracket with the screw holes on the side of the Switch.

Figure 5 Attaching the Mounting Brackets

2Using a #2 Philips screwdriver, install the M3 flat head screws through the mounting bracket holes into the Switch.

3Repeat steps 1 and 2 to install the second mounting bracket on the other side of the Switch.

4You may now mount the Switch on a rack. Proceed to the next section.

2.3.3Mounting the Switch on a Rack

1Position a mounting bracket (that is already attached to the Switch) on one side of the rack, lining up the two screw holes on the bracket with the screw holes on the side of the rack.

GS1920 Series User’s Guide

Hardware Panels

This chapter describes the front panel and rear panel of the Switch and shows you how to make the hardware connections.

3.1 Front Panel

The following figures show the front panels of the Switch. See Section 3.3 on page 30 for information on the LEDs.

Figure 7 Front Panel: GS1920-24

Figure 8 Front Panel: GS1920-24HP

Figure 9 Front Panel: GS1920-48

Figure 10 Front Panel: GS1920-48HP

3.1.1 Gigabit Ethernet Ports

The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps Gigabit, the speed can be 10 Mbps, 100 Mbps or 1000 Mbps and the duplex mode can be half duplex or full duplex.

An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps) and duplex mode (full duplex or half duplex) of the connected device.

An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover Ethernet cable.

GS1920 Series User’s Guide

Chapter 3 Hardware Panels

Four 1000Base-T Ethernet ports are paired with a mini-GBIC slot to create a dual personality interface. The Switch uses up to one connection for each mini-GBIC and 1000Base-T Ethernet pair. The mini-GBIC slots have priority over the Gigabit ports. This means that if a mini-GBIC slot and the corresponding GbE port are connected at the same time, the GbE port will be disabled.

Note: The dual personality ports change to fiber mode directly when inserting the fiber module.

When auto-negotiation is turned on, an Ethernet port negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support autonegotiation or turns off this feature, the Switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer Ethernet port are the same in order to connect.

3.1.1.1 Default Ethernet Negotiation Settings

The factory default negotiation settings for the Gigabit ports on the Switch are:

•Speed: Auto

•Duplex: Auto

•Flow control: Off

•Link Aggregation: Disabled

3.1.1.2Auto-crossover

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 Gigabit port connections. Auto-crossover ports automatically sense whether they need to function as crossover or straight ports, so crossover cables can connect both computers and switches/hubs.

3.1.2 Mini-GBIC Slots

These are slots for mini-GBIC (Gigabit Interface Converter) transceivers. A transceiver is a single unit that houses a transmitter and a receiver. The Switch does not come with transceivers. You must use transceivers that comply with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.

You can change transceivers while the Switch is operating. You can use different transceivers to connect to Ethernet switches with different types of fiber-optic or even copper cable connectors.

To avoid possible eye injury, do not look into an operating fiber-optic module’s connectors.

•Type: SFP connection interface

•Connection speed: 1 Gigabit per second (Gbps)

3.1.2.1Transceiver Installation

Use the following steps to install a mini-GBIC transceiver (SFP module).

GS1920 Series User’s Guide

Chapter 3 Hardware Panels

1Insert the transceiver into the slot with the exposed section of PCB board facing down.

2Press the transceiver firmly until it clicks into place.

3The Switch automatically detects the installed transceiver. Check the LEDs to verify that it is functioning properly.

4Close the transceiver’s latch (latch styles vary).

5Connect the fiber optic cables to the transceiver. Figure 11 Transceiver Installation Example

Figure 12 Connecting the Fiber Optic Cables

3.1.2.2Transceiver Removal

Use the following steps to remove a mini-GBIC transceiver (SFP module).

1Remove the fiber optic cables from the transceiver.

2Open the transceiver’s latch (latch styles vary).

3Pull the transceiver out of the slot.
