Setup for the DES-1252 Fast

Ethernet Smart Switch

Before physically installing the switch, please make note of the following

recommendations:

A. Install the DES-1252 in a fairly cool and dry place. Technical

Specifications such as operating temperatures and, other important

information can be found in the manual located on the supplied CD.

B. Install the DES-1252 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 switch for ventilation.

D. Visually inspect the DC power jack and make sure that it is fully

secured to the power adapter.

E. Install the DES-1252 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 switch

and protect the switch case from scratching.

Attach the adhesive rubber pads to the bottom

Rack Mounting

The DES-1252 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 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 Cables

The DES-1252 has 48 ports that support 10/100Mbps Fast Ethernet;

it also has 4 10/100/1000Base-T Ports and 2 Combo SFPs. It runs

full/half duplex transfer mode for 10/100Mbps and full duplex transfer

mode for 1000Mbps. Each port on the DES-1252 supports Auto-

MDI/MDI-X. Auto-MDI/MDI-X is a feature that enables the switch to

auto sense what kind of cable is used on a port (straight or crossover).

This allows any type of cables to be used with the switch regardless

of what device is being connected.

AC Power

The Switch utilizes an AC power supply of 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 DES-1252 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 to properly access and view the

configuration..

In order to login and configure the switch via an Ethernet connection, the

PC must have an IP address in the same range as the switch. For

example, if the switch has an IP address of 192.168.0.1, the PC should

have an IP address of 192.168.0.x (where x is a number between 2 and

254), and a subnet mask of 255.255.255.0.

Open your web browser and enter http://192.168.0.1 (the factory-default

IP address) in the address box. Then press <Enter>.

The web configuration can also be accessed through the SmartConsole

Utility. Open the SmartConsole Utility and double-click the switch as it

appears in the Monitor List. This will automatically load the web

configuration in your web browser.

When the following logon box appears, enter "admin" for the password.

Press Ok to enter the main configuration window. (Figure 3.)
