Getting to Know Your Switch
1.1 Introduction
This chapter introduces the main features and applications of the Switch.
The GS1915 Series consists of the following models:
• GS1915-8
• GS1915-8EP
References to PoE models in this User's Guide only apply to GS1915-8EP.
The Switch is a layer-2 Ethernet switch that only does switching.
All models are referred to as the “Switch” in this guide.
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.

1.1.3 ZON Utility
Chapter 1 Getting to Know Your Switch
Switch will reboot and restore the factory default
With its built-in Web Configurator, including the Neighbor Management feature (Section 7.2.1 on page
75), 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 40.
1.1.4 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) +
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 wireless router, an IP telephone and a general outdoor router that are not
within reach of a power outlet.
Figure 1 PoE Example Application
GS1915 Series User’s Guide
21
Chapter 1 Getting to Know Your Switch
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 2 Backbone Application
1.2.3 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.
GS1915 Series User’s Guide
22
Chapter 1 Getting to Know Your Switch
Figure 3 Bridging 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.
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.
Figure 4 High Performance Switched Workgroup Application
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.
GS1915 Series User’s Guide
23
Chapter 1 Getting to Know Your Switch
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 5 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 36.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup or restore. See Section
31.8.1 on page 248.
• SNMP. The Switch can be monitored and/or managed by an SNMP manager. See Section 32.8.1 on
page 262.
• Cluster Management. Cluster Management allows you to manage multiple switches through one
switch, called the cluster manager. See Chapter 36 on page 280.
• 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 40.
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.
GS1915 Series User’s Guide
24
Chapter 1 Getting to Know Your Switch
• 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.

The Switch can be:
• Placed on a desktop.
• Wall-mounted on a wall.
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 Installation Procedure
1 Make sure the Switch is clean and dry.
2 Remove the adhesive backing from the rubber feet.
GS1915 Series User’s Guide
26
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 6 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 Wall Mounting
The Switch can be mounted on a wall. You may need screw anchors if mounting on a concrete or brick
wall.
2.4.1 Installation Requirements
• Use screws with 6 mm – 8 mm (0.24" – 0.31") wide heads.
• The distance between the screws: 176 mm.
The following figure shows the screw specifications used for wall mounting.
• D = 7.00 mm
• H = 2.00 mm
• L= 15.50 mm
• d = 3.50 mm
GS1915 Series User’s Guide

Chapter 2 Hardware Installation and Connection
Do the following to attach your Switch to a wall.
1 Select a position free of obstructions on a wall strong enough to hold the weight of the Switch.
2 Mark two holes on the wall at the appropriate distance apart for the screws.
WARNING! Be careful to avoid damaging pipes or cables located inside
the wall when drilling holes for the screws.
3 If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into the full
depth of the holes, then insert the screws into the anchors. Do NOT insert the screws all the way in –
leave a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do NOT insert the screws
all the way in – leave a gap of about 0.5 cm.
4 Make sure the screws are fastened well enough to hold the weight of the Switch with the connection
cables.
5 Align the holes on the back of the Switch with the screws on the wall. Hang the Switch on the screws.
Note: Make sure there is enough clearance between the wall and the Switch to allow
ventilation.
