Preface
About This Guide
This guide provides instructions on how to install and configure the
TL2-G244 24-Port Gigabit Layer 2 Switch w/ 4 Shared Mini-GBIC
Slots.
This guide is mainly divided into four parts:
1. Hardware Installation: Step-by-step hardware installation
procedure.
2. Using Web User Interface: A startup guide to for the command
line interface.
3. Command Reference: Information about the function
descriptions and configuration settings.
Terms/Usage
In this guide, the term “Switch” (first letter capitalized) refers to this
Switch, and “switch” (first letter lower case) refers to other Ethernet
switches. Some technologies refer to terms “switch”, “bridge” and
“switching hubs” interchangeably, and both are commonly accepted
for Ethernet switches.
Note
Alerts you to supplementary information.
Caution
Indicates potential property damage or personal injury.

Hardware Installation
This chapter provides unpacking and installation information for TL2-G244.
Unpacking
Open the shipping carton and carefully unpack its contents. Please consult the
packing list located in the User Manual to make sure all items are present and
undamaged. If any item is missing or damaged, please contact your local reseller
for replacement.
TL2-G244
Multi-Language Quick Installation Guide
CD-ROM (User’s Guide)
Power Cord (1.8 m / 5.9 ft.)
RS-232 Cable (3 m / 9.8 ft.)
Rack Mounting Kit
Rubber feet
If any item is found missing or damaged, please contact the local reseller for
replacement.
Switch Installation For safe switch installation and operation, it is recommended that you:
Visually inspect the power cord to see that it is secured fully to the AC
power connector.
Make sure that there is proper
heat dissipation and adequate
ventilation around the switch.

Do not place heavy objects on the switch.
Desktop or Shelf
Installation When installing the switch on a desktop or shelf, the rubber feet included with the
device must be attached on the bottom at each corner of the device’s base. Allow
enough ventilation space between the device and the objects around it.
Figure 1 – Attach the adhesive rubber pads to the bottom
Rack Installation
The switch can be mounted in an EIA standard size 19-inch rack, which can be
placed in a wiring closet with other equipment. To install, attach the mounting
brackets to the switch’s side panels (one on each side) and secure them with the
screws provided.
Figure 2 – Attach the mounting brackets to the Switch
Then, use the screws provided with the equipment rack to mount the switch in the

24-Port Gigabit Layer 2 Switch w/ 4 Shared Mini-GBIC Slots
3-2
rack.
Figure 3 – Mount the Switch in the rack or chassis
Caution
Safety Instructions
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that
the amount of air flow required for safe operation of the equipment is not
compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical
loading.
D) Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits
might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when
addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (e.g. use of power strips)."
Plugging in the AC
Power Cord
Users may now connect the AC power cord into the rear of the switch and to an
electrical outlet (preferably one that is grounded and surge protected).
Figure 4 – Plugging the switch into an outlet
Power Failure
As a precaution, the switch should be unplugged in case of power failure. When
power is resumed, plug the switch back in.

Using the Web User Interface
After a successful physical installation, you can configure the Switch, monitor the network status, and display
statistics using a web browser.
Supported Web
Browsers The embedded Web-based Management currently supports the following web
browsers:
A) Internet Explorer 6 or higher
B) Netscape 8 or higher
C) Mozilla
D) Firefox 1.5/2.0 or higher
Connecting to the
Switch You will need the following equipment to begin the web configuration of your
device:
1. A PC with a RJ-45 Ethernet connection
2. A standard Ethernet cable
Connect the Ethernet cable to any of the ports on the front panel of the switch
and to the Ethernet port on the PC.
Figure 5 – Connected to an end node via Ethernet cable
Login Web-based
Management In order to login and configure the switch via an Ethernet connection, the PC must have an IP address in the same subnet as the switch. For example, if the
switch has an IP address of 192.168.10.200, the PC should have an IP address
of 192.168.10.x (where x is a number between 1 ~ 254), and a subnet mask of
255.255.255.0.
Open the web browser and enter 192.168.10.200 (the factory-default IP address)
in the address bar. Then press <Enter>.
