10/100BASE-TX Twisted-Pair Ports (Port1~24)

These ports support network speeds of either 10Mbps or 100Mbps, and can operate in half- and full- duplex

transfer modes. These ports also support automatic MDI/MDI-X crossover detection, giving true “plug and

play” capability. Just plug the network cable directly into the hub; you can use either straight-through or

crossover cable.

10/100/1000BASE-T Twisted Pair Ports (Port 25~26)

The DES-1226G is equipped with two Gigabit twisted pair ports that are auto negotiable 10/100/1000Mbps

and also support auto MDI/MDIX crossover detection. These two ports can operate in half- and full- duplex

modes.

SFP(Mini GBIC) Ports (Option Port 25~26)

The Switch is equipped with two SFP(Mini GBIC) ports, supported optional 1000BASE-X SFP(Mini GBIC)

module.

Note: When the port is set to “Forced Mode”, the Auto MDI/MDIX will be disabled.

AC Power Connector

This is a three-pronged connector that supports the power cord. Plug in the female connector of the

provided power cord into this connector, and the male into a power outlet. Supported input voltages range

from 100~240V AC at 50~60Hz.

Reset

The Reset button is to reset all the settings back to the factory defaults.

Note: Be sure that you record the settings of your device, or else all settings will be erased when pressing

the “Reset” button.

3. Installation

The site where you place the DES-1226G may greatly affect its performance. When installing, take the following into

your consideration:

±

Install the DES-1226G in a fairly cool and dry place. See the

Technical Specifications

for the acceptable

temperature and humidity operating ranges.

±

Install the DES-1226G in a site free from strong electromagnetic field generators (such as motors), vibration,

dust, and direct exposure to sunlight.

±

Leave at least 10cm (about 4 inches) of space at the front and rear of the Switch for ventilation.

±

Install the DES-1226G on a sturdy, level surface that can support its weight, or in an EIA standard-size

equipment rack.

±

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-1226G 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 the screws provided with the equipment rack to mount the Switch in the rack.

Mount the Switch in the rack.

Connecting Network Cable

The DES-1226G 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 DES-1226G 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 DES-1226G can be used with 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.

4. Configuration

Through the Web browser you can configure Switch settings such as VLAN, Trunking, QoS… etc.

Using the Switch’s Web Management Utility, you can easily discover all the D-Link

Web-Smart Switches in your

network, assign the IP Address, change the password, and upgrade

new firmware.

View Trap:

The Trap function can receive the events that occur from the Web-Smart Switch in the Monitor List.

There is a light indicator behind the

“View Trap”

button. When the light is green, it indicates that no trap has been transmitted, and when it is red,

it indicates that a new trap has been transmitted, reminding us to view the trap. (Figure 2)

Figure 2.

When the

“View Trap”

button is clicked, a Trap Information window will pop up, displaying trap information including the Symbol, Time, Device

IP, and the Event occured. (Figure 3)

The symbol “
