CHAPTER 1

Getting to Know Your Switch

1.1 Introduction

This chapter introduces the main features and applications of the Switch.

The GS2220 Series consists of the following models:

• GS2220-10

• GS2220-10HP

• GS2220-28

• GS2220-28HP

• GS2220-50

• GS2220-50HP

References to PoE models in this User's Guide only apply to GS2220-10HP, GS2220-28HP and GS222050HP.

The Switch is a layer-2 Ethernet switch that only does switching.

The Switch supports NebulaFlex which can set the Switch to operate in either standalone or Nebula cloud management mode. When the Switch is in standalone mode, it can be configured and managed by the Web Configurator, through Telnet, any terminal emulator program using the Command Line Interface (CLI), or through third-party SNMP management. When the Switch is in Nebula cloud management mode, it can be managed and provisioned by the Zyxel Nebula Control Center (NCC).

All models are referred to as the “Switch” in this guide.

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

1.1.1 Management Method

With its built-in Web Configurator, managing and configuring the Switch is easy. In addition, the Switch can also be managed through Telnet, any terminal emulator program using the Command Line Interface (CLI), or third-party SNMP management.

1.1.2 Management Modes

NebulaFlex means you can set the Switch to operate in either standalone or cloud mode (but not both at the same time).

Use the Web Configurator to configure and manage the Switch directly in standalone mode or use Nebula Control Center (NCC) to configure and manage the Switch in cloud mode. The Nebula Control Center (NCC) is an alternative cloud-based network management system that allows you to remotely manage and monitor the Switch. You may also access a minimized version of the Web Configurator in cloud mode.

Nebula Cloud Management

To have Nebula manage the Switch, you must first register it at the Nebula web portal at https:// nebula.zyxel.com, and ensure that Nebula Control Center Discovery is enabled in Basic Setting > Cloud Management > Nebula Control Center Discovery in the Switch Web Configurator.

Note: See the Switch’s datasheet for the feature differences between standalone and

Nebula cloud management modes. You can find the Switch’s datasheet at the Zyxel website.

See the NCC (Nebula Control Center) User’s Guide for how to configure the Switch using Nebula.

Note: The Switch goes into Nebula-managed mode automatically after it can access the

Nebula web portal and is successfully registered there. Its login password and settings are then overwritten with what you have configured in the Nebula web portal.

From Nebula-managed to Standalone

To return to direct management standalone mode, just remove (unregister) the Switch from the organization or site in the Nebula web portal. The settings.

Switch will reboot and restore the factory default

1.1.4 ZON Utility

With its built-in Web Configurator, including the Neighbor Management feature (Section 7.2.1 on page

98), viewing, managing and configuring the Switch and its neighboring devices is simplified.

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 (Windows operation system). For more information on ZON Utility see Section 4.3 on page 55.

1.1.5 Web Configurator Networked AV Mode

Aside from the Web Configurator in Standard mode, you can switch to Networked AV mode that is specifically designed to simplify configuration and management of the Switch for AVoIP (Audio-Video over Internet Protocol) application. In AV over IP, the AV transmitter is the transmitter, the AV receiver is the receiver, and the matrix switch is a standard IP Switch. See Section 4.4 on page 59 for details on using the Setup Wizard screen for configuring the Switch’s Networked AV mode’s basic and advanced settings.

1.1.6 PoE

The Switch is a Power Sourcing Equipment (PSE) because it provides a source of power through its Ethernet ports. Each device that receives power through an Ethernet port is a Powered Device (PD).

The Switch can adjust the power supplied to each PD according to the PoE standard the PD supports. PoE standards are:

• IEEE 802.3af Power over Ethernet (PoE)

• IEEE 802.3at Power over Ethernet (PoE) +

• IEEE 802.3bt Power over Ethernet (PoE) ++

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

1.2.2 Backbone Example 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, and so on.

1.2.3 Bridging or Fiber Uplink Example Application

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 through the Switch. You can provide a super-fast uplink connection by using a Gigabit Ethernet or SFP port on the Switch.

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

1.2.4 High Performance Switching Example

The Switch is ideal for connecting two networks that need high bandwidth. In the following example, use link aggregation (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.

This helps you switch to higher-speed LANs without the need for replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.
