The external Redundant Power Supply connector is used to connect the DGS-3100 Series to one of the following
supported units:
DGS-3100 Series Device
Supported RPS Unit
DGS-3100-24
DPS-300
DGS-3100-48
DPS-500
DGS-3100-24P/48P
DPS-600
DGS-3100-24TG
DPS-300
An auto-switch circuit automatically switches to the external RPS once the internal power supply fails. Transition from
internal to external supply does not disturb normal operation.
•
The AC power connector is a standard three-pronged connector that supports the power cord. Plug the female
connector of the provided power cord into this socket, and the male side of the cord into a power outlet. Supported
input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz.
