Management Methods
The LevelOne GSW-2490TXM SNMP Switch supports following
management methods:
Console and Telnet Management
Web-based Management
SNMP Network Management
Console and Telnet Management
Console Management is done through the RS-232 Console Port.
Managing the LevelOne GSW-2490TXM SNMP Switch in this
method requires a direct connection between PC and the LevelOne
GSW-2490TXM SNMP Switch. While Telnet management is done
over the network. Once the LevelOne GSW-2490TXM SNMP
Switch is on the network, you can use Telnet to Log in and change
the configuration.
SNMP Network Management
SNMP (Simple Network Management Protocol) provides a means
to monitor and control network device, and to manage
configurations, statistic collection, performance, and security.
Data is passed from SNMP agents, which are hardware & software
5
processes reporting activity in each network device to the
workstation console used to oversee the network. The agent return
information contained in a MIB (Management Information Base),
which is a data structure that defines what is obtainable from the
device and what can be controlled.

Hardware Description
This section mainly describes the hardware of the LevelOne GSW-
2490TXM SNMP Switch, and gives a functional overview of the
Switch.
The physical dimensions of the LevelOne GSW-2490TXM
SNMP Switch are: 440mmx 225mmx 44.5mm ( Lx Wx H )
Hardware Description
The LevelOne GSW-2490TXM SNMP Switch is a fixed 24-port
auto-sensing Ethernet RJ-45 connectors, and its chassis contains
two expansion slots. The optional modules come with the built-in
CPU module.
The Front Panel
The Front Panel of the LevelOne GSW-2490TXM SNMP Switch
consists of 24x auto-sensing 10/100Mbps Ethernet RJ-45 Ports, two
optional expansion slots, and Console port. The LED Indicators are
also located on the front panel of the Switch.

to another Switch or workstation without changing non-crossover or
crossover cabling. ]
Expansion Slots :
For two of the following Optional modules :
1 Port Gigabit 1000Base-T Intelligent Switch Modules,
1 Port Gigabit 1000Base-SX/LX Intelligent Fiber Modules.
1 Port 100Base-FX Intelligent Fiber Module
Console Port :
Console Management can be done through the Console Port. It
requires a direct connection between the LevelOne GSW-2490TXM
SNMP Switch and an end station ( PC ) via a RS-232 cable.
LED Indicators
All LED indicators are located on the front panel of the LevelOne
GSW-2490TXM SNMP Switch. They provide a real-time indication
of system and operational status. The following table
gives descriptions of the LED status and their meanings.

Rear Panel
The 3-pronged power plug, On/off Switch are located at the Rear
Panel of the LevelOne GSW-2490TXM SNMP Switch. ( The
Ventilation fan is located on the side of the Switch ). The Switch will
work with AC in the range 100-240V AC, 50-60Hz.
Figure 2-3. The Rear Panel of the LevelOne GSW-2490TXM SNMP
Switch
Power On
After all network cables are connected, plug the power cord into the
power socket on the back panel and the other end into a power
outlet. Turn the power On using the power Switch on the back
panel.
Check the front panel Power indicator to see if power is properly
supplied. The Switch uses a universal power supply that requires no
additional adjustment.
Diagnostic Test
After the installation is completed and AC power is applied to the
Switch, the system will automatically perform a diagnostic test.
When the Power LED is on within 5 seconds, the Diagnostic status
8
LEDs will soon flash red.
When the Switch passes the self-test within 15 seconds, the Link
/ACT LED turns on.
Note : If the Switch fails the self-test, the Diag LED will blink.

Connecting to the Network
This section provides the installation procedure and instructions for
assigning IP address.
Pre-Installation Requirements
Before you start hardware installation, make sure your installation
environment has below items:
PCs with 10/100Mbps Ethernet NICs/ 100Mbps Fiber NICs:
Your PC must have a standard Ethernet interface to connect to
the Switch.
UTP cable with RJ45 connectors/ Fiber cable with MT-RJ/
VF-45 connectors: Check if the cable and connectors work
properly.
A power outlet: 100 to 240V AC at 50 to 60 Hz: Make sure
that the Switch power is accessible and cables can be
connected easily.
9
Dedicated power supply: Use dedicated power circuits or
power conditioners to supply reliable electrical power to the
network devices.
A dry cool place: Keep the Switch away from moisture. Avoid
direct sunlight, heat source, and high amount of electromagnetic
interference around.
Mounting tools: If you intend to mount the Switch on a rack,
make sure you have all the tools, mounting brackets, screws
etc.
Caution:
Cabling must be away from sources of electrical noise such as
radio, computers, transmitters, broadband amplifiers, power
lines and keep away from TVs, hair dryers, and microwave.
Air flow around the Switch and through its vents on the rear
cannot be restricted.
Mounting the Switch
The LevelOne GSW-2490TXM SNMP Switch is suitable for use in
an office environment where it can be rack-mounted in standard EIA
19-inch racks or standalone.
Desktop Mounting
1. Set the Switch on a sufficiently large flat space with a power
outlet nearby, and about the center of all networked devices.
2. Make sure mounting surface on the bottom of the Switch is
grease dust free.
3. Remove adhesive backing from your Rubber Feet.
Figure 3-1. Attaching Rubber Feet to each corner
on the bottom of the Switch
4. Apply the Rubber Feet to each corner on the bottom of the
Switch. These footpads can prevent the Switch from
shock/vibrations.
10
Caution: Do not place objects on top of the Switch.
Rack-mounted Installation
The LevelOne GSW-2490TXM SNMP Switch come with a rack-
mounted kid and can be mounted in an EIA standard size, 19-inch
Rack. The Switch can be placed in a wiring closet with other
equipment.
Perform the following steps to rack mount the Switch:
A. Position one bracket to align with the holes on one side of the
Switch and secure it with the smaller bracket screws. Then
attach the remaining bracket to the other side of the Switch.
Figure 3-2. Attach mounting brackets with screws
B. After attached both mounting brackets, position the LevelOne
GSW-2490TXM SNMP Switch ( UTP/MT-RJ/VF-45 ) Switch in
the rack by lining up the holes in the brackets with the
appropriate holes on the rack. Secure the Switch to the rack with
a screwdriver and the rack-mounting screws.
