CHAPTER 1

Getting to Know Your Switch

1.1 Introduction

This chapter introduces the main features and applications of the Switch.
The XGS1930 Series consists of the following models:
• XGS1930-28
• XGS1930-28HP
• XGS1930-52
• XGS1930-52HP
References to PoE models in this User's Guide only apply to XGS1930-28HP and XGS1930-52HP.
The Switch is a smart managed switch with one power slot for single power supply. The Switch provides four SFP+ slots for uplink. By integrating static route functions, the Switch performs wire-speed layer-3 routing in addition to layer-2 switching.
The Switch supports NebulaFlex for hybrid mode 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. When the Switch is in Nebula cloud management mode, it can be managed and provisioned by the Zyxel Nebula Control Center (NCC).
The following table describes the hardware features of the Switch by model.
Table 1 XGS1930 Series Comparison Table

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.
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.
1.1.2 Mode Changing
This section describes how to change the Switch’s management mode.
Note: If you change the Switch’s management mode from standalone mode to Nebula-
managed mode, the configuration settings of the Switch will be overwritten with what you have configured in Nebula.
Chapter 1 Getting to Know Your Switch
Note: If you change the Switch’s management mode from Nebula-managed mode to
standalone mode, the Switch will reset to its factory-default settings.
From Standalone to Nebula Cloud Management
To manage your Switch through Nebula, connect the Switch to the Internet, and register it to a site and organization at the Nebula web portal (https://nebula.zyxel.com).
See the following steps or the Switch Quick Start Guide for how to do device registration.

1 Download and open the Zyxel Nebula Mobile app in your mobile device. Click Sign Up to create a
myZyxel account or enter your existing account information to log in.
2 Create an organization and site, or select an existing site using the Zyxel Nebula Mobile app.
3 Select a site and scan the Switch's QR code to add it to the site. You can find the QR code:
• On a label on the Switch or
• On its box or
• In the Web Configurator at Basic > Cloud Management > Nebula Switch Registration.
See Section 3.3 on page 37 for more information about the CLOUD LED or Section 7.2 on page 74 for more information about the Hybrid Mode field in the Status screen to see if the Switch goes into Nebula cloud management mode successfully.
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 Switch will reboot and restore the factory default settings.
1.1.3 ZON Utility
With its built-in Web Configurator, including the Neighbor Management feature (Section 7.2.1 on page
76), 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 44.
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(ABHT.0) is a firmware version for XGS1930-28 where 4.50 is the firmware trunk version, ABHT identifies the XGS1930-28 and .0 is the first release of trunk version 4.50.
Table 2 Models and Firmware Versions

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 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.
XGS1930 Series User’s Guide
23
Chapter 1 Getting to Know Your Switch
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 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.
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 link aggregation (trunking) to connect these two networks.
XGS1930 Series User’s Guide
24
Chapter 1 Getting to Know Your Switch
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 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.
1.2.4.1 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 4 Shared Server Using VLAN Example

Chapter 1 Getting to Know Your Switch

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 Section 8.11 on page 113 or 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 40.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup or restore. See Section
36.8.1 on page 299.
• SNMP. The Switch can be monitored and/or managed by an SNMP manager. See Section 37.7.1 on
page 312.
• Cluster Management. Cluster Management allows you to manage multiple switches through one switch, called the cluster manager. See Chapter 41 on page 330.
• 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 44.

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.

CHAPTER 2
Connection

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 Freestanding Installation Procedure

1 Make sure the Switch is clean and dry.
2 Remove the adhesive backing from the rubber feet.
XGS1930 Series User’s Guide
27
Chapter 2 Hardware Installation and Connection
3 Attach 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. Figure 5 Attaching Rubber Feet
4 Set 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.
Cautions:
• Avoid stacking fanless Switches to prevent overheating.
• Ensure enough clearance around the Switch to allow air circulation for cooling.
• Do NOT remove the rubber feet as it provides space for air circulation.

2.4 Mounting 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 rack-mounting kit.
Note: Make sure there is enough clearance between each equipment on the rack for air
circulation.
2.4.1 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.
2.4.2 Precautions
• Make sure the rack will safely support the combined weight of all the equipment it contains. The maximum weight a bracket can hold is 21.5 kg.
• 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.
