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

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.

2. Hardware Description

This section mainly describes the hardware of the LevelOne GSW2490TXM SNMP Switch, and gives a functional overview of the Switch.

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

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.

3. 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.

 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.

Caution: Do not place objects on top of the Switch.

Rack-mounted Installation

The LevelOne GSW-2490TXM SNMP Switch come with a rackmounted 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.

Figure 3-3. Mount the 24TP+1Fiber Module Switch in an EIA

standard 19-inch Rack

Note: For proper ventilation, allow about at least 4 inches ( 10 cm ) of clearance on the front and 3.4 inches ( 8 cm ) on the back of the Switch. This is especially important for enclosed rack installation.

Connecting to the Switch

The Console port is a male DB-9 connector that enables a connection to a PC or terminal for monitoring and configuring the LevelOne GSW-2490TXM SNMP Switch. Use the supplied RS-232 cable with a female DB-9 connector to connect a terminal or PC to the Console port.

The Console configuration ( out of band ) allow you to set your Switch to enable a user at a remote console terminal to communicate with the LevelOne GSW-2490TXM SNMP Switch as if the console terminal were directly connected to it.

Figure 3-4. Connecting the LevelOne GSW-2490TXM SNMP Switch

to a terminal via RS-232 cable

When the connection between Switch and PC is finished, turn on the PC and run a terminal emulation program or Hyper Terminal and configure its communication parameters to match the following default characteristics of the console port:

Baud Rate: 9600 bps Data Bits: 8 Parity: none Stop Bit: 1 Control flow: None
