2 Go to the Organization-wide > Configure > License & inventory > Devices screen.
3 Select the Switch you want to remove (unregister) from the organization.
4 Click Actions, then click Remove from organization.
It will take a while for the Switch to reboot and reset to factory default.
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.

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
25
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
26
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.

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

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.

3.1.1 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.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover
GS1920v2 Series User’s Guide
37
Chapter 3 Hard wa r e Pa n els
Ethernet cable.
Four 1000Base-T Ethernet ports are paired with an SFP slot to create a dual personality interface. The
Switch uses up to one connection for each SFP and 1000Base-T Ethernet pair. The SFP slots have priority
over the Gigabit ports. This means that if an SFP slot and the corresponding GbE port are connected at
the same time, the GbE port will be disabled.
Note: The dual personality ports change to fiber optic mode directly when inserting the fiber
module.
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 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 (GS1920-8HPv2, GS1920-24HPv2, and GS1920-48HPv2)
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).
3.1.3 SFP Slots
These are slots for SFP (Small Form-Factor Pluggable) transceivers. A transceiver is a single unit that
houses a transmitter and a receiver. The Switch does not come with transceivers. You must use
transceivers that comply with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement
(MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different transceivers to
connect to Ethernet switches with different types of fiber optic or even copper cable connectors.
• Type: SFP connection interface
• Connection speed: 100/1000 Mbps
GS1920v2 Series User’s Guide
38
WARNING! To avoid possible eye injury, do not look into an operating
fiber optic module’s connectors.
HANDLING! All transceivers are static sensitive. To prevent damage from
electrostatic discharge (ESD), it is recommended you attach an ESD
preventive wrist strap to your wrist and to a bare metal surface when
you install or remove a transceiver.
STORAGE! All modules are dust sensitive. When not in use, always keep
the dust plug on. Avoid getting dust and other contaminant into the
optical bores, as the optics do not work correctly when obstructed with
dust.
3.1.3.1 Transceiver Installation
Use the following steps to install a transceiver.
1 Attach an ESD preventive wrist strap to your wrist and to a bare metal surface.
2 Align the transceiver in front of the slot opening.
3 Make sure the latch is in the lock position (latch styles vary), then insert the transceiver into the slot with
the exposed section of PCB board facing down.
Chapter 3 Hardware Panels
4 Press the transceiver firmly until it clicks into place.
5 The Switch automatically detects the installed transceiver. Check the LEDs to verify that it is functioning
properly.
6 Remove the dust plugs from the transceiver and cables (dust pl ug s ty l es vary).

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.

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
Chapter 5 Initial Setup Example
CHAPTER 5
Initial Setup Example
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.
In this example, you want to configure port 1 as a member of VLAN 2.
Figure 44 Initial Setup Network Example: VLAN
1 Click Advanced Application > VLAN > VLAN Configuration in the navigation panel and click the Static
VLAN Setup link.

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.
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.
GS1920v2 Series User’s Guide
63
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.
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.

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 managem ent
purposes. The following figure shows an example.

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
GS1920v2 Series User’s Guide
86
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
every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
Note: VLAN is unidirectional; it only governs outgoing traffic.
8.4.2 Setting up
Click Basic Setting > Switch Setup in the navigation panel to display the screen as shown. The VLAN
setup screens change depending on whether you choose 802.1Q or Port Based in the VLAN Type field in

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 lev els. 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

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 auto-negotiation
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 auto-negotiation 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

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 IEEE802.3x flow control in full duplex mode and backpressure flow control in half
duplex mode.
IEEE802.3x 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. Some features are only
available for the Ethernet ports (1 to 8 for GS1920-8HPv2, 1 to 24 for GS1920-24HPv2, and
1 to 48 for GS1920-48HPv2).
The PoE models supports the IEEE 802.3at High Power over Ethernet (PoE) standard.
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.
Figure 73 Powered Device Examples
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.

LABEL DESCRIPTION
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 powe r 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 30 W 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
by Type 2 devices. If the connected PD requires a Class 4 current when it is turned on, it will be
powered up in this mode.
Force-802.3at – the Switch provides PD Wide Range Detection (WRD) with power of up to 33 W on
the port without performing PoE classification. Select this if the connected PD does not comply
with any PoE standard.
Note: Wide Range Detection (WRD) is integrated into Force-802.3at mode. Your
previous WRD configuration will be retained if you upgrade firmware to ZyNOS
4.70(xxxx.7) (‘xxxx’ refers to the Switch’s model code) or later with WRD enabled.
If you now want to disable WRD, you need to use Maintenance > Erase Running-
Configuration to reset the Switch to its default settings. Note you will lose all
current settings.
