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
