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 Technical

Specification 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 SmartConsole Utility

Through the Web Browser you can configure the Switch such as VLAN,

Trunking, QoS… etc.

The following instruction guides you to install the SmartConsole 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:\ SmartConsole 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 -> SmartConsole Utility

and execute the SmartConsole Utility. (Figure 1.)

Figure 1

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.

Note: Use Internet Explorer 5.5 or above Web browser to properly

access and view the configuration.

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 SmartConsole Utility, you do not need to remember the IP

Address, select the device shown in the Monitor List of the

SmartConsole 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 comes up, the screen will

display the device status. (Figure 4.)

Figure 4.

Setup Menu

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

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

There are eleven options: System Setting, Trap Setting, Port Setting,

SNMP Setting, Password Access Control, 802.1Q VLAN, Trunking,

IGMP Snooping, 802.1D Spanning Tree, Port Mirroring, 802.1p Default

Priority, Safeguard Engine, Broadcast Storm Control, 802.1X Setting,

Static MAC, Dynamic Forwarding Table and Statistics. (Figure 5).

Figure 5.

Tool

You can also find the Tool menu on the main page (Figure 6). Click on it

and scroll down as shown in Figure 6, and you can see four options:

Reset, Config Backup & Restore, Firmware Backup & Upload and

System Reboot.
