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.

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.
Login
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.)

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.
