1 1. Introduction
1.1 Overview
The SNMP-GSH2004L Web Smart Switch is a standard switch that meets all IEEE
802.3/u/x/z Gigabit, Fast Ethernet specifications. The switch has 20 10/100/1000Mbps TP
ports and 4 Gigabit TP/SFP transceiver slots; it supports http and SNMP interface for switch
management. The network administrator can logon the switch to monitor, configure and
control each port’s activity. In addition, the switch implements the QoS (Quality of Service),
VLAN, and Trunking. It is suitable for office application.
Others the switch increase support the Power saving for reduce the power consumption
with "ActiPHY Power Management" and "PerfectReach Power Management" two technique.
It could efficient saving the switch power with auto detect the client idle and cable length to
provide different power.
In this switch, Port 21, 22, 23, 24 includes two types of media --- TP and SFP Fiber (LC);
these ports supports 10/100/1000Mbps TP or 100/1000Mbps SFP Fiber with auto-detected
function. 1000Mbps SFP Fiber transceiver is used for high speed connection expansion.

¾LED Indicators:
Comprehensive LED indicators display the status of the switch and the network (see the
LED Indicators chapter below).
¾1000BASE-T Gigabit Ethernet Ports (Port 1~24)
The Switch four Gigabit twisted pair ports, supported auto negotiable 10/100/1000Mbps
and auto MDI/MDIX crossover detection function, this function gives true “plug and play”
capability, just need to plug-in the network cable to the hub directly and don’t care if the end
node is NIC (Network Interface Card) or switch and hub. These ports can operate in
half-duplex mode for 10/100Mbps and full- duplex mode for 10/100/1000Mbps.
¾Combo SFP Ports (Port 21~24)
The Switch is equipped with four combo SFP ports, supported optional 1000BASE-SX/LX
SFP module. The 1000BASE-T port 21~24 are the same ports with the SFP port 21~24,
when plug in the SFP module, the device will activate SFP, and the RJ45 port will be
disabled.
* Note: When the port was set to “Forced Mode”, the Auto MDI/MDIX will be disabled.
¾Mode button:
The Mode button is to change the LED’s status to Link/Act or Speed, and reset all the
setting back to the factory default by pressing the mode button for 10 seconds.
* Note: Be sure that you recorded the setting of your device; else all the setting will be
erased when pressing the “Mode” (reset) button 10 seconds.

2.2.2 Rear Panel
The 3-pronged power plug and on/off switch are placed at the rear panel of the switch right
side shown as below.
2.3 Installation Site Preparation
You can mount SNMP-GSH2004L either on desktop or on a 19-inch rack. If you plan to
mount the switch on desktop, please choose a steady, level surface in a well-ventilated
area that is free from excessive dust. In any case, the installation site chosen for your
switch has to comply with the following requirements:
The surface where you want to mount the switch must be able to sustain at least 2.4kg.
Do not place heavy objects (more than 3kg) on top of the switch.
The location must preferably be free from excessive dust, away from heat vent, hot-air
exhaust and direct sunlight.
The switch should not be placed near large electric motors or other strong
electromagnetic sources. As a reference, the strength of the electromagnetic field on
site should not exceed the (RFC) standards for IEC 801-3, Level 2(3V/M) field strength.
The air temperature in the location should be within a range of 32 to 122 °F (0 to 50°C).
The relative humidity in the location should not exceed 90% non-condensing humidity.
The distance between the RJ-45 port and the standard network interface should not
exceed 100 meters.
Adequate space should be allowed in front of all the ports, so that each port is easily
accessible for cable connections.
Leave at least 10cm(4 inch) of space around the switch to allow heating dissipation

2.4 Rack Mounting
The SNMP-GSH2004L can be mounted on a standard size 19-inch rack, which can in turn
be placed in a wiring closet with other equipments.
Before you can mount the switch on the rack, first you must attach the mounting brackets
on both sides of the switch with screws, and then mount it as a unit on the rack.
To mount the unit on a rack, please follow the steps below:
Step 1. First, align the holes on the bracket with the holes on both side of the switch.
Step 2. Insert screws into the holes and then fasten the bracket on one side of the switch
with a screwdriver.
Step 3. Repeat Step 1 and 2 to fasten the bracket on the other side of the switch.
Step 4. Mount the unit on the rack and align the notches on both brackets with mounting
holes on the rack, and then secure the unit with suitable screws.

2.5 Desktop Installation
The SNMP-GSH2004L has four rubber pads attached on each corner of its underside.
These pads serve as cushioning against vibration and prevent the switch from sliding off its
position. They also allow adequate ventilation space when you place the switch on top of
another device.
Desktop installation
The location you choose to install your switch and the way you configure your network
may greatly affect its performance. Please see the previous section for “installation site”
preparation.
Do not place more than 1.5kg (6.6lbs) of weight on the top of the switch.
Leave at least 10cm of space around the switch to allow proper heating dissipation.

2.6 Cabling Requirements
For 100BASE-TX and 1000Base-T ports
The 24 RJ-45 station ports and the 1000Base-T ports of the optional Gigabit-Copper
module require Cat. 5 twisted-pair UTP/STP cable for connection. When configuring within
the 10/100/1000BASE-T cabling architecture, the cable distance should be within 100m.
The following table summarizes the cable requirement for 10/100/1000BASE-TX
connection:
10BASE-T 100 ohm Category 3, 4, 5 UTP/STP cable
100 ohm Category 5 UTP/STP cable
100BASE-TX
100 ohm Category 5 UTP/STP cable or better (CAT 5E
recommended)
1000BASE-T
Auto MDI/MDI-X function
The SNMP-GSH2004L is equipped with Auto-MDI/MDI-X function, which allows you to use
straight-through cable even when connecting to another switch/hub. Simply use the
straight-through cable for all types of 10/100BASE-TX connections, either to a PC or to a
networking device such as other hub or switch.

AirLive SNMP-GSH2004L User’s Manual 12
The SNMP-GSH2004L can be configured by web based interface, including System
Information, Ports Configuration, VLAN setting, Aggregation, QoS setting, IGMP Snooping,
Mirroring, SNMP, Loop Detection, Broadcast Strom, configuration/ backup/recovery, log out,
and so on. The device based smart switch supports main stream browsers, such as IE,
Firefox and Chrome…etc to configure the device function. All functions are illustrated
below.
4.1 Setup your computer for Web management
The Concept of Subnet
Under the TCP/IP environment, network devices must be on the same subnet in order to
see each other. This means before you can configure the switch through web browser, you
must set your computer to the same subnet as the switch. For two network devices to be on
the same subnet, they must have the following 2 criteria:
Their IP address must be on the same subnet. For example, if one IP address is
192.168.2.1. The other’s IP address must be 192.168.2.x (x is any number between 2
and 254) for Class C subnet. To find out the IP address information for your computer.
Under WinXP/Vista/Win7/Win8, please open Command Line window and type
“ipconfig”.
They must have the same subnet mask. For example, if one machine is 255.255.255.0.
The other machine must also set to the same 255.255.255.0 mask.
Configure your computer’s IP
Before accessing the switch through web browser, please follow the instruction below to
configure your computer’s IP to the same subnet as the switch. If your switch’s IP has not
been changed, it should have the following factory default value:
The switch’s Default IP
IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0

Now if your computer’s IP is not in the same subnet as the switch, please follow the steps
below to change the computer’s IP:
Manual IP setting
Step 1. Double click on the network connection status icon on the task bar. This
should bring up a window showing the status of the current network
connection. If there is no network status icon on the task bar, please go to
the “Start -> Settings -> Network -> Local Connection” of the task bar’s
Start menu.
Step 2. Clock on the “property” icon.
Step 3. Double click on the “Internet Protocol (TCP/IP)
Step 4. Click on “Use the following IP address” button and enter the computer’s
address manually. This IP address must be on the same subnet as the
switch but different from the switch’s IP. Please make sure the IP is not
used by other network device. If the switch’s IP address is of factory’s
default value. We recommend enter the following for computer’s IP:
