Setup The DES-1250G Switch

The setup of the Switch can be performed using the following steps:

A. Install the DES-1250G in a fairly cool and dry place. See the

Technical Specifications for the acceptable operation temperature

and humidity ranges.

B. Install the DES-1250G in a site free from strong electromagnetic

field generators (such as motors), vibration, dust, and direct

exposure to sunlight.

C. Leave at least 10cm (about 4 inches) of space at the front and rear

of the hub for ventilation.

D. Visually inspect the DC power jack and make sure that it is fully

secured to the power adapter.

E. Install the DES-1250G on a sturdy, level surface that can support

its weight, or in an EIA standard-size equipment rack.

F. When installing the Switch on a level surface, attach the rubber feet

to the bottom of each device. The rubber feet cushion the hub and

protect the hub case from scratching.

Attach the adhesive rubber pads to the bottom

Rack Mounting

The DES-1250G can be mounted in an EIA standard-size, 19-inch rack,

which can be placed in a wiring closet with other equipment. Attach the

mounting brackets to both sides of the Switch (one at each side), and

secure them with the provided screws.

Use the screws provided. Then, use screws provided with the

equipment rack to mount the Switch in the rack.

Mount the Switch in the rack

Connecting Network Cable

The DES-1250G supports 2 ports of 10/100/1000Mbps Gigabit

Ethernet. It runs full-/half- duplex transfer mode for 10/100Mbps and

full-duplex transfer mode for 1000Mbps. Each port on the DES-

1250G supports Auto-MDI/MDI-X. Auto-MDI/MDI-X is a feature that

eliminates the need for worrying about using either a standard or

crossover cable—you can use either one—and allows any port to be

an uplink port.

AC Power

The DES-1250G can be used with AC power supply 100~240V AC,

50~60Hz. The power switch is located at the rear of the unit adjacent to

the AC power connector and the system fan. The switch’s power supply

will adjust to the local power source automatically and may be turned on

without having any or all LAN segment cables connected.

 10/100BASE-TX Twisted-Pair Ports (Port1~48)

These ports support network speeds of either 10Mbps or 100Mbps,

and can operate in half- and full- duplex transfer modes. These ports

also support automatic MDI/MDI-X crossover detection, giving true

“plug and play” capability. Just plug the network cable directly into the

hub; you can use either straight-through or crossover cable.

 1000BASE-T Twisted Pair Ports (Port 49~50)

The DES-1250G is equipped with two Gigabit twisted pair ports that

are auto negotiable 10/100/1000Mbps and also support auto

MDI/MDIX crossover detection. These two ports can operate in half-

and full- duplex modes.

 Mini-GBIC Ports (Option Port 49~50)

The Switch is equipped with two mini-GBIC ports, supported optional

1000BASE-SX/LX mini-GBIC module.

Note: When the port is set to “Forced Mode”, Auto MDI/MDIX will

be disabled.

Installing the Web Management

Utility

Through the Web browser you can configure switch functions such as

VLAN, Trunking, QoS… etc.

The following instruction guides you to install the Web Management

utility.

1. Insert the Utility CD in the CD-ROM Drive.

2. From the Start menu on the Windows desktop, choose Run.

3. In the Run dialog box, type D:\Web Management Utility\setup.exe

(D:\ depends where your CD-ROM drive is located) and click OK.

4. Follow the on-screen instructions to install the utility.

5. Upon completion, go to Program Files ->

web_management_utility and execute the Web Management

utility. (Figure 1.)

Configuring the Switch

The DES-1250G has a Web GUI interface for smart switch

configuration. The Switch can be configured through the Web browser.

A network administrator can manage, control and monitor the switch

from the local LAN. This section indicates how to configure the Switch

to enable its smart functions.

Use Internet Explorer 5.0 or above Web browser.

Before you configure this device, note that when the Web Smart Switch

is configured through an Ethernet connection, make sure the manager

PC must be set on the same IP network. For example, when the default

network address of the default IP address of the Web Smart Switch is

192.168.0.1, then the manager PC should be set at 192.168.0.x (where x

is a number between 2 and 254), and the default subnet mask is

255.255.255.0.

Enter IP address http://192.168.0.1 (the factory-default IP address

setting) to the address location. (Figure 2.)

Figure 2.

Or through the Web Management Utility, you do not need to remember

the IP Address, Select the device shown in the Monitor List of the Web

Management Utility to settle the device on the Web browser.

When the following dialog page appears, remain enter the default

password "admin" and press Login to enter the main configuration

window. (Figure 3.)

Figure 3.

After entering the password, the main page appears and the screen will

display the device status. (Figure 4.)

Figure 4.

Setup Menu

When the main page appears, find the Setup menu on the left side of

the screen (Figure 5). Click on the setup item that you want to configure.

There are eleven options: Port Settings, VLAN Settings, Trunk Setting,

Mirror Setting, Device Status, System Settings, Trap Setting, Password

Setting, Backup Setting, and Reset Setting as shown in the Main Menu

screen.
