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 ~ 240 VAC at 50 ~ 60 Hz.
The rear panel also includes an outlet for an optional external power supply. When power fails, the optional external RPS will take
over all the power immediately and automatically.

The rear panel of the DC power version of the Switch includes an opening designed to accommodate the DC power wiring
assembly. See the installation instructions in this Section for details.

Side Panel Description

The right-hand side panel of the Switch contains a system fan, while the left hand panel includes a system fan and a heat vent.
The system fans are used to dissipate heat. The sides of the system also provide heat vents to serve the same purpose. 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.
