Rear Panel Description
The rear panels of DES-3828, DES-3828DC, DES-3828P and DES-3852 are described separately below.
DES-3828
The rear panel of DES-3828 contains ports 27 and 28, (1000BASE-TX), an AC power connector, and an outlet for an optional
external RPS.

For details on ports 27 and 28, see the “Ports” description above. The rear panel includes an outlet for an optional external
redundant power supply. When power fails, the optional external RPS will take over all the power immediately and automatically.
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.
DES-3828P
The rear panel of DES-3828P contains ports 27 and 28, (1000BASE-TX), a heat vent, an AC power connector, and an outlet for
an optional external RPS.

For details on ports 27 and 28, see the “Ports” description above. The rear panel includes a heat vent for the system fan. The
system fan is used to dissipate heat. Do not block this opening, and leave at least 6 inches of space at the rear 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. The rear panel also includes an outlet for an optional external redundant power supply. When power
fails, the optional external RPS will take over all the power immediately and automatically. 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 maximum output capacity for PoE is 370W. The default power feed for PoE is set
at 15.4W per port, but can be set from 1-16.8W per port. See the PoE Configuration in Section 6 for instructions on how to change
this setting.
DES-3828DC

The rear panel of the DC power version of the Switch includes ports 27 and 28, (1000BASE-TX), and an opening designed to
accommodate the DC power wiring assembly. See the installation instructions in Section 2 for details.
DES-3852
The rear panel of the DES-3852 contains ports 51 and 52, (1000BASE-TX), an AC power connector, an RS-232 console port and
an outlet for an optional external RPS.
