Rear Panel Description
The rear panel of the Switch contains an AC power connector. The AC power connector is a standard three-
pronged connector that supports the power cord. Plug-in the female connector of the provided power cord
into this socket, and the male side of the cord into a power outlet. The Switch automatically adjusts its power
setting to any supply voltage in the range from 100 to 240 VAC at 50 to 60 Hz. Connect the Kensington-
compatible security lock, at the rear of the switch, to a secure immovable device(only for DES-1210-10/ME).
Insert the lock into the notch and turn the key to secure the lock(only for DES-1210-10/ME).

Side Panel Description
The left- and right-hand panels of the Switch have heat vents to dissipate heat. Do not block these openings,
and leave at least 6 inches of space at the rear and sides of the Switch for proper ventilation. Be reminded
that without proper heat dissipation and air circulation, system components might overheat, which could lead
to system failure.
