Setup The DGS-1248T Gigabit Smart

Switch

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

A. Install the DGS-1248T in a fairly cool and dry place. See the Technical

Specifications for the acceptable operation temperature and humidity

ranges.

B. Install the DGS-1248T 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 DGS-1248T 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 DGS-1248T can be mounted in an EIA standard-size, 19-inch rack,

which can be placed in a wiring closet with other equipments. 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 DGS-1248T supports 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 DGS-1248T 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 DGS-1248T 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.

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.

Configuring the Switch

The DGS-1248T 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, 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 on the Main Menu
