1.1.1 Management Modes

NebulaFlex for ‘hybrid mode’ means you can set the Switch to operate in only one of either direct standalone or cloud mode (not both at the same time). The Nebula Control Center (NCC) is an alternative cloud-based network management system that allows you to remotely manage and monitor the Switch.

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. You may also access a minimized version of the web configurator in cloud mode.

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

Nebula Cloud Management

To have Nebula manage the Switch, you must first register it at the Nebula web portal at http:// nebula.zyxel.com, and ensure that Nebula Control Center Discovery is enabled in Basic > Cloud Management > Nebula Control Center Discovery in the Switch web configurator (enabled by default).

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.

1.1.2 Mode Changing

This section describes how to change the Switch’s management mode.

Note: When you change the Switch’s management mode from standalone mode to Nebulamanged mode, the configuration settings of the Switch will be overwritten with what you have configured in Nebula.

When you change the Switch’s management mode from Nebula-manged mode to standalone mode, the Switch will reset to its factory-default settings.

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

From Standalone to Nebula Cloud Management

To manage your Switch via Nebula, connect the Switch to the Internet, and register it to a site and organization at the Nebula web portal (http://nebula.zyxel.com).

See the following steps or the Switch Quick Start Guide for how to do device registration.

Chapter 1 Getting to Know Your Switch

1.1.3 ZON Utility

With its built-in web configurator, including the Zyxel One Network (ZON) Neighbor Management feature (Section 7.4 on page 75), viewing, managing and configuring the Switch and its neighboring devices is easy.

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 operating system). For more information on ZON Utility see Section 7.3 on page 70.

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 2 Models and Firmware Version

1.2 Applications

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

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

1.2.1 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

1.2.2 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/SFP port on the Switch.

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

Chapter 1 Getting to Know Your Switch

Figure 2 Bridging Application

1.2.3 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

1.2.4 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 107.

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

1.2.4.1 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

1.3 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 44.

•FTP. Use FTP for firmware upgrades and configuration backup/restore. See Section 39.7.1 on page 346.

•SNMP. The Switch can be monitored by an SNMP manager. See Section 40.7.1 on page 357.

•Cluster Management. Cluster Management allows you to manage multiple switches through one switch, called the cluster manager. See Chapter 43 on page 372.

•ZON Utility. ZON Utility is a program designed to help you deploy and perform initial setup on a network more efficiently. See Section 7.3 on page 70.

•NCC (Zyxel Nebula Control Center). With the NCC, you can remotely manage and monitor the Switch through a cloud-based network management system. See Section 8.12 on page 104 or the NCC User’s Guide for detailed information about how to access the NCC and manage your Switch via the NCC. See the NCC User’s Guide for how to configure Nebula managed devices.

GS1920v2 Series User’s Guide

Chapter 1 Getting to Know Your Switch

1.4 Good 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.

•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.

GS1920v2 Series User’s Guide

CHAPTER 2

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.

•Desk-mounted under a table.

•Wall-mounted on a wall

•Rack-mounted on a standard EIA rack.

Note: Ask an authorized technician to attach the Switch under a desk or to the rack/wall. See the Installation Requirements sections in this chapter to know the types of screws and screw drivers for each mounting method.

WARNING! Failure to use the proper screws may damage the unit.

See Table 1 on page 20 for the comparison table of the hardware installation methods for each model. To start using the Switch, simply connect the power cables and turn it on.

WARNING! The surface of the Switch could be hot when it’s functioning. Do NOT put your hands on it. You may get burned. This could happen especially when you’re using the GS1920-8HPv2. It’s a compact and fanless Switch capable of supplying Power over Ethernet (PoE).

WARNING! This Switch is not suitable for use in locations where children are likely to be present.

2.2 Desktop Installation Procedure

1Make sure the Switch is clean and dry.

2Remove the adhesive backing from the rubber feet.

GS1920v2 Series User’s Guide

Chapter 2 Hardware Installation and Connection

3Attach the rubber feet to each corner on the bottom of the Switch. These rubber feet help protect the Switch from shock or vibration and ensure space between devices when stacking.

Note: Rubber feet will be attached to the GS1920-8HPv2 by default. To make sure of air circulation, do NOT remove them.

Figure 5 Attaching Rubber Feet

4Set 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.

5Make sure there is at least 40 mm of clearance around and from the surface to the bottom of the Switch to allow air circulation and the attachment of cables and the power cord.

Note: Make sure that you meet the requirements of clearance when you use the Switch for stacking. It’s recommended to only use the Switch with Fans in a stack. See Table 1 on page 20 to see whether your Switch has fans.

WARNING! Do NOT block the ventilation holes nor store things on the Switch. Allow clearance for the ventilation holes to prevent your Switch from overheating. This is especially crucial when your Switch doesn’t have fans. Overheating could affect the performance of your Switch, or even damage it.
