External Redundant Power System

The DPS-500/700 is a redundant power-supply unit designed to conform to the voltage requirements of the switches
being supported. The DPS-500/700 can be installed into a DPS-900, or DPS-800 rack mount unit.
CAUTION: DO NOT connect the RPS to AC power before the DC power cable is connected. This
might damage the internal power supply. The DPS-500 only works on the DGS-3620-
28TC/28SC/52T, whereas the DPS-700 only supports the DGS-3620-28PC/52P.

DPS-900

The DPS-900 is a standard-size rack mount (5 standard units in height) designed to hold up to eight DPS-500
redundant power supplies. However, it cannot hold eight DGS-700 modules.
The RPS can be mounted in a standard 19" rack. Use the following diagram to guide you.
