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.

Hardware Installation and
2.1 Installation Scenarios
This chapter shows you how to install and connect the Switch.
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
27
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.
GS1915 Series User’s Guide

Press the RESTORE button for more than 6 seconds to have the Switch restore the factory
default file. See Section 3.3 on page 34 for more information about the LED behavior.
3.1.1 Gigabit Ethernet Ports
The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps Gigabit
Ethernet, the speed can be 10 Mbps, 100 Mbps or 1000 Mbps. The duplex mode can be half duplex or
full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps)
and duplex mode (full duplex or half duplex) of the connected device.
GS1915 Series User’s Guide
30
Chapter 3 Hardware Panels
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover
Ethernet cable.
When auto-negotiation is turned on, an Ethernet port negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer Ethernet port does not support autonegotiation or turns off this feature, the Switch determines the connection speed by detecting the signal
on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off, an Ethernet
port uses the pre-configured speed and duplex mode when making a connection, thereby requiring
you to make sure that the settings of the peer Ethernet port are the same in order to connect.
3.1.1.1 Default Ethernet Negotiation Settings
The factory default negotiation settings for the Gigabit ports on the Switch are:
• Speed: Auto
•Duplex: Auto
• Flow control: Off
• Link Aggregation: Disabled
3.1.1.2 Auto-crossover
All ports support auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so you
may use either a straight-through Ethernet cable or crossover Ethernet cable for all Gigabit port
connections. Auto-crossover ports automatically sense whether they need to function as crossover or
straight ports, so crossover cables can connect both computers and switches or hubs.
3.1.2 PoE
The Switch supports both the IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at Power over
Ethernet (PoE) plus standards. 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).

3.2.1 Grounding
Grounding is a safety measure to direct excess electric charge to the ground. It prevents damage to
the Switch, and protects you from electrocution. Use the grounding screw on the rear panel and the
ground wire of the AC power supply to ground the Switch.
The grounding terminal and AC power ground where you install the Switch must follow your country’s
regulations. Qualified service personnel must ensure the building’s protective earthing terminals are
valid terminals.
Installation of Ethernet cables must be separate from AC power lines. To avoid electric surge and
electromagnetic interference, use a different electrical conduit or raceway (tube/trough or enclosed
conduit for protecting electric wiring) that is 15 cm apart, or as specified by your country’s electrical
regulations.
Any device that is located outdoors and connected to this product must be properly grounded and
surge protected. To the extent permissible by your country’s applicable law, failure to follow these
guidelines could result in damage to your Switch which may not be covered by its warranty.
Note: The specification for surge or ESD protection assumes that the Switch is properly
grounded.
1 Remove the M4 ground screw from the Switch’s rear panel.
2 Secure a green or yellow ground cable (16 AWG or smaller) to the Switch's rear panel using the M4
ground screw.
Figure 11 Grounding
3 Attach the other end of the ground cable to a grounding bar located on the rack where you install the
Switch or to an on-site grounding terminal.
Figure 12 Attach Ground Cable to Grounding Bar or On-site Grounding Terminal
GS1915 Series User’s Guide

Chapter 3 Hardware Panels
4 The grounding terminal of the server rack or on-site grounding terminal must also be grounded and
connected to the building’s main grounding electrode. Make sure the grounding terminal is connected
to the buildings grounding electrode and has an earth resistance of less than 10 ohms, or according to
your country’s electrical regulations.
Figure 13 Connecting to the Building’s Main Grounding Electrode
If you are uncertain that suitable grounding is available, contact the appropriate electrical inspection
authority or an electrician.
This device must be grounded. Do this before you make other
connections.

4.3 Zyxel One Network (ZON) Utility
ZON Utility is a program designed to help you deploy and manage a network more efficiently. It detects
devices automatically and allows you to do basic settings on devices in the network without having to
be near it.
The ZON Utility issues requests through Zyxel Discovery Protocol (ZDP) and in response to the query, the
device responds back with basic information including IP address, firmware version, location, system
and model name in the same broadcast domain. The information is then displayed in the ZON Utility
screen and you can perform tasks like basic configuration of the devices and batch firmware upgrade
in it. You can download the ZON Utility at www.zyxel.com and install it in a computer (Windows
operating system).

5.1 Overview
This chapter shows how to set up the Switch for an example network.
The following lists the configuration steps for the initial setup:
• Create a VLAN
• Set Port VID
• Configure Switch Management IP Address
5.1.1 Create a VLAN
VLANs confine broadcast frames to the VLAN group in which the ports belongs. You can do this with
port-based VLAN or tagged static VLAN with fixed port members.
CHAPTER 5
Initial Setup Example
In this example, you want to configure port 1 as a member of VLAN 2.
Figure 35 Initial Setup Network Example: VLAN
1 Click Advanced Application > VLAN > VLAN Configuration in the navigation panel and click the Static
VLAN Setup link.
GS1915 Series User’s Guide
60
Chapter 5 Initial Setup Example
2 In the Static VLAN screen, select ACTIVE, enter a descriptive name in the Name field and enter 2 in the
VLAN Group ID field for the VLAN2 network. Use the default VLAN type, Normal, in the VLAN Type field.
Note: The VLAN Group ID field in this screen and the VID field in the IP Setup screen refer to the
same VLAN ID.
3 Since the VLAN2 network is connected to port 1 on the Switch, select Fixed to configure port 1 to be a
permanent member of the VLAN only.
4 To ensure that VLAN-unaware devices (such as computers and hubs) can receive frames properly, clear
the TX Tagging check box to set the Switch to remove VLAN tags before sending.
5 Click Add to save the settings to the run-time memory. Settings in the run-time memory are lost when the
Switch’s power is turned off.
5.1.2 Set Port VID
Use PVID to add a tag to incoming untagged frames received on that port so that the frames are
forwarded to the VLAN group that the tag defines.
GS1915 Series User’s Guide
61
Chapter 5 Initial Setup Example
In the example network, configure 2 as the port VID on port 1 so that any untagged frames received on
that port get sent to VLAN 2.
Figure 36 Initial Setup Network Example: Port VID
1 Click Advanced Application > VLAN > VLAN Configuration in the navigation panel. Then click the VLAN
Port Setup link.
2 Enter 2 in the PVID field for port 1 and click Apply to save your changes back to the run-time memory.
Settings in the run-time memory are lost when the Switch’s power is turned off.
5.1.3 Configure Switch Management IP Address
If the Switch fails to obtain an IP address from a DHCP server, the Switch will use 192.168.1.1 as the
management IP address. You can configure another IP address in a different subnet for management
purposes. The following figure shows an example.
GS1915 Series User’s Guide
62
Chapter 5 Initial Setup Example
Figure 37 Initial Setup Example: Management IP Address
1 Connect your computer to any Ethernet port on the Switch. Make sure your computer is in the same
subnet as the Switch.

8.4 Switch Setup
Use this to choose the VLAN (Virtual Local Area Network) type, map the priority queue, and configure
other settings.
8.4.1 Introduction to VLANs
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same groups;
the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the
subscribers. When properly configured, VLAN prevents one subscriber from accessing the network
GS1915 Series User’s Guide
82
resources of another on the same LAN, thus a user will NOT see the printers and hard disks of another
user in the same building.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable
logical broadcast domain. In traditional switched environments, all broadcast packets go to each and

LABEL DESCRIPTION
Priority Queue Assignment
IEEE 802.1p defines up to eight separate traffic types by inserting a tag into a MAC-layer frame that contains bits to
define class of service. Frames without an explicit priority tag are given the default priority of the ingress port. Use
the next fields to configure the priority level-to-physical queue mapping.
The Switch has eight physical queues that you can map to the eight priority levels. On the Switch, traffic assigned to
higher index queues gets through faster while traffic in lower index queues is dropped if the network is congested.
Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d standard (which
incorporates the 802.1p).
To map a priority level to a physical queue, select a physical queue from the drop-down menu on the right.
Priority 7 Typically used for network control traffic such as router configuration messages.
Priority 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay).
Priority 5 Typically used for video that consumes high bandwidth and is sensitive to jitter.
Priority 4 Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network
Architecture) transactions.
Priority 3 Typically used for “excellent effort” or better than best effort and would include important
Priority 2 This is for “spare bandwidth”.
Priority 1 This is typically used for non-critical “background” traffic such as bulk transfers that are allowed

8.5 IP Setup
Use the IP Setup screen to configure the default gateway device, the default domain name server and
add IP domains.
8.5.1 IP Interfaces
The Switch needs an IP address for it to be managed over the network. When the Switch (in Standalone
mode) fails to obtain an IP address from a DHCP server, the static IP address 192.168.1.1 will be
automatically added and used as the Switch’s management IP address.
On the Switch, an IP address is not bound to any physical ports. Since each IP address on the Switch
must be in a separate subnet, the configured IP address is also known as IP interface (or routing
domain). In addition, this allows routing between subnets based on the IP address without additional
routers.
You can configure multiple routing domains on the same VLAN as long as the IP address ranges for the
domains do not overlap. To change the IP address of the Switch in a routing domain, simply add a new
routing domain entry with a different IP address in the same subnet.
GS1915 Series User’s Guide
84
You can configure up to 64 IP domains which are used to access and manage the Switch from the ports
belonging to the pre-defined VLANs.
Note: You must configure a VLAN first. Each VLAN can only have one management IP
address.

Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port automatically
to obtain the connection speed and duplex mode that both ends support. When autonegotiation is turned on, a port on the Switch negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer port does not support autonegotiation or turns off this feature, the Switch determines the connection speed by detecting
the signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is
turned off, a port uses the pre-configured speed and duplex mode when making a connection,
thus requiring you to make sure that the settings of the peer port are the same in order to
connect.

Chapter 8 Basic Setting
Table 32 Basic Setting > Port Setup (continued)
LABEL DESCRIPTION
Flow Control A concentration of traffic on a port decreases port bandwidth and overflows buffer memory
causing packet discards and frame losses. Flow Control is used to regulate transmission of signals
to match the bandwidth of the receiving port.
The Switch uses IEEE 802.3x flow control in full duplex mode and backpressure flow control in half
duplex mode.
IEEE 802.3x flow control is used in full duplex mode to send a pause signal to the sending port,
causing it to temporarily stop sending signals when the receiving port memory buffers fill.
Back Pressure flow control is typically used in half duplex mode to send a "collision" signal to the
sending port (mimicking a state of packet collision) causing the sending port to temporarily stop
sending signals and resend later. Select Flow Control to enable it.

8.7 PoE Status
Note: The following screens are available for the PoE models only.
A powered device (PD) is a device such as an access point or a switch, that supports PoE (Power over
Ethernet) so that it can receive power from another device through an Ethernet port.
In the figure below, the IP camera and IP phone get their power directly from the Switch. Aside from
minimizing the need for cables and wires, PoE removes the hassle of trying to find a nearby electric
outlet to power up devices.

You can also set priorities so that the Switch is able to reserve and allocate power to certain PDs.
Note: The PoE (Power over Ethernet) devices that supply or receive power and their
connected Ethernet cables must all be completely indoors.

Power-Up Set how the Switch provides power to a connected PD at power-up.
802.3af – the Switch follows the IEEE 802.3af Power over Ethernet standard to supply power to the
connected PDs during power-up.
Legacy – the Switch can provide power to the connected PDs that require high inrush currents at
power-up. Inrush current is the maximum, instantaneous input current drawn by the PD when first
turned on.
Pre-802.3at – the Switch initially offers power on the port according to the IEEE 802.3af standard,
and then switches to support the IEEE 802.3at standard within 75 milliseconds after a PD is
connected to the port. Select this option if the Switch is performing 2-event Layer-1 classification
(PoE+ hardware classification) or the connected PD is NOT performing Layer 2 power
classification using Link Layer Discovery Protocol (LLDP).
802.3at – the Switch supports the IEEE 802.3at High Power over Ethernet standard and can supply
power of up to 30W per Ethernet port. IEEE 802.3at is also known as PoE+ or PoE Plus. An IEEE
802.3at compatible device is referred to as Type 2. Power Class 4 (High Power) can only be used

This field displays the maximum number of ICMPv6 error messages which are allowed to transmit
in a given time interval. If the bucket is full, subsequent error messages are suppressed.
This field displays the time period (in milliseconds) during which ICMPv6 error messages of up to
the bucket size can be transmitted. 0 means no limit.
This field displays whether the Switch’s interface can automatically generate a link-local address
through stateless auto-configuration.
This field displays the Switch’s link-local IP address and prefix generated by the interface. It also
shows whether the IP address is preferred, which means it is a valid address and can be used as a
sender or receiver address.
This field displays the Switch’s global unicast address to identify this interface.
This field displays the IPv6 multicast addresses of groups the Switch’s interface joins.
enabled on the interface.
This field displays the number of consecutive neighbor solicitations the Switch sends for this
interface.

This field displays how long (in milliseconds) a neighbor is considered reachable for this interface.
This field displays whether the Switch acts as a DHCPv6 client to get an IPv6 address from a
DHCPv6 server.
An Identity Association (IA) is a collection of addresses assigned to a DHCP client, through which
the server and client can manage a set of related IP addresses. Each IA must be associated with
exactly one interface.

An IA_NA option contains the T1 and T2 fields, but an IA_TA option does not. The DHCPv6 server
uses T1 and T2 to control the time at which the client contacts with the server to extend the
lifetimes on any addresses in the IA_NA before the lifetimes expire.
the Switch sends a Rebind message to any available server.
Active when the Switch obtains addresses from a DHCpv6 server and the TA is created.
Renew when the TA’s address lifetime expires and the Switch sends out a Renew message.
Rebind when the Switch does not receive a response from the original DHCPv6 server and sends
out a Rebind message to another DHCPv6 server.
SID This field displays the DHCPv6 server’s unique ID.
Address This field displays the Switch’s global address which is assigned by the DHCPv6 server.
