UNPACKING AND INSTALLATION
This chapter provides unpacking and installation information for the Switch.
Unpacking
Open the shipping cartons of the Switch and carefully unpacks its contents.
The carton should contain the following items:
±
One DGS-1248T Web Smart 48-Port 10/100/1000Mbps Gigabit
Switch
±
One AC power cord, suitable for your area’s electrical power
connections
±
Four rubber feet to be used for shock cushioning
±
Screws and two mounting brackets
±
CD-ROM with Web Management Utility and Manual
If any item is found missing or damaged, please contact your local reseller for
replacement.
Installation
The site where you install the hub stack may greatly affect its performance.
When installing, consider the following pointers:
Install the Switch in a fairly cool and dry place. See
Technical Specifications
for the acceptable temperature and humidity operating ranges.
Install the Switch in a site free from strong electromagnetic field generators
(such as motors), vibration, dust, and direct exposure to sunlight.
Leave at least 10cm of space at the front and rear of the hub for ventilation.
Install the Switch on a sturdy, level surface that can support its weight, or in an
EIA standard-size equipment rack. For information on rack installation, see the
next section, Rack Mounting
.

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.

Rack Mounting
The Switch 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 at the Switch’s front panel (one on each side), and secure them with
the provided screws.
Figure 2. Combine the Switch with the provided screws
Then, use screws provided with the equipment rack to mount each Switch in
the rack.

Connecting Network Cable
The
Switch
supports
1000Mbps
Gigabit
Ethernet
that
runs
in
Auto-negotiation mode and 10Mbps Ethernet or 100Mbps Fast Ethernet that
runs both in half- and full-duplex mode and 1000Mbps Gigabit Ethernet runs
in full-duplex mode using four pair of Category 5 Cable.
These RJ-45 ports are Auto-MDI type port. The Switch can auto transform to
MDI-II or MDI-X type, so you can just make an easy connection that without
worrying if you are using a standard or crossover RJ45 cable.
There are 4 additional SFP/mini-GBIC slots for optional SFP/mini-GBIC
modules.
AC Power
The Switch uses the AC power supply 100-240V AC, 50-60 Hz. 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.

The Switch is equipped with Four SFP(Mini GBIC) ports, supporting
optional 1000BASE-X SFP(Mini GBIC) transceivers.
Note: When the port is set to “Forced Mode”, Auto MDI/MDIX will be
disabled.
Reset
The Reset button is used to reset all settings back to the factory defaults.
Note: Be sure that you record the settings of your device, or else all settings
