1.1.2 ZON Utility

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

78), 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 51.

The following table shows which firmware version supports ZON and Neighbor Management (Smart Connect) for each Switch. The firmware on each Switch is identified by the firmware trunk version, followed by a unique model code and release number in brackets. For example, 4.50(ABMK.0) is a firmware version for GS1920-48HPv2 where 4.50 is the firmware trunk version, ABMK identifies the GS192048HPv2 and .0 is the first release of trunk version 4.50.

Table 3 Models and Firmware Version

1.1.3 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 GS1920-8HPv2, GS1920-24HPv2, and GS1920-48HPv2 come with a Power-over-Ethernet (PoE) feature. The GS1920-8HPv2, GS1920-24HPv2, and GS1920-48HPv2 support 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.

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

1.2 Example Applications

This section shows a few examples of using the Switch in various network environments. Note that the Switch in the figure is just an example Switch and not your actual Switch.

1.2.1 PoE Example Application

The following example figure shows a Switch supplying PoE (Power over Ethernet) to Powered Devices (PDs) such as an IP camera, a w ireless router, an IP telephone and a general outdoor router that are not within reach of a power outlet.

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

Figure 2 PoE Example Application

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.

Figure 3 Backbone Application

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

1.2.3 Bridging or Fiber Optic 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 manage rs to centra lize multiple servers at a single location.

Figure 4 Bridging or Fiber Optic Uplink Example Application

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.

Figure 5 High Performance Switched Workgroup Application

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

1.2.5 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 or more groups. With VLAN, a station cannot directly talk to or hear from stations that are not in the same groups unless such traffic first goes through a router.

1.2.5.1 Tag-based VLAN Example

Ports in the same VLAN group share the same frame broadcast domain thereby 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 6 Shared Server Using VLAN Example

1.3 Ways to Manage the Switch

Use any of the following methods to manage the Switch.

• NCC (Zyxel Nebula Control Center). With the NCC, you can remotely manage and monitor the Switch through a cloud-based network management system. See the NCC User’s Guide for detailed information about how to access the NCC and manage your Switch through the NCC. See the NCC User’s Guide for how to configure Nebula managed devices.

• Web Configurator. This is recommended for everyday management of the Switch using a (supported) web browser. See Chapter 4 on page 48.

• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup or restore. See Section

41.8.1 on page 354.

• SNMP. The Switch can be monitored and/or managed by an SNMP ma na ge r. See Section 42.8.1 on

page 368.

• Cluster Management. Cluster Management allows you to manage multiple switches through one switch, called the cluster manager. See Chapter 46 on page 385.

• ZON Utility. ZON Utility is a program designed to help you deploy and perform initial setup on a network more efficiently. See Section 4.3 on page 51.

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

1.4 Good Habits for Managing the Switch

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

• Change the password. Use a password that is 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.

• 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.

2.2 Safety Precautions

Please observe the following before using the Switch:

• It is recommended to ask an authorized technician to attach the Switch on a desk or to the rack or wall. Use the proper screws to prevent damage to the Switch. See the Installation Requirements sections in this chapter to know the types of screws and screwdrivers for each mounting method.

• Make sure there is at least 2 cm of clearance on the top and bottom of the Switch, and at least 5 cm of clearance on all four sides of the Switch. This allows air circulation for cooling.

• Do NOT block the ventilation holes nor store cables or power cords on the Switch. Allow clearance for the ventilation holes to prevent your Switch from overheating. This is especially crucial when your Switch does not have fans. Overheating could affect the performance of your Switch, or even damage it.

• The surface of the Switch could be hot when it is functioning. Do NOT put your hands on it. You may get burned. This could happen especially when you are using a fanless Switch.

• The Switches with fans are not suitable for use in locations where children are likely to be present.

To start using the Switch, simply connect the power cables to turn it on.

2.3 Desktop Installation Procedure

1 Make sure the Switch is clean and dry.
