1 install the des-1026g in a fairly cool and dry place. see technical specifications for the acceptable temperature and humidity operating ranges.
2 install the des-1026g in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.
3 leave at least 10cm (about 4 inches) of space at the front and rear of the hub for ventilation.
4 install the des-1026g on a sturdy, level surface that can support its weight, or in an eia standard-size equipment rack.
5 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 protects the hub case from scratching.
rack mounting
the des-1026g can be mounted in an eia standard-size, 19-inch rack, which can be placed in a wiring closet with other equipments. 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.
connecting network cable
the des-1026g 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-1026g 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-1026g 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.
