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.

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.
Figure 5. Use the screws provided, then use the equipment rack to 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.
