Installing a Redundant Power Supply

About the RPS2-EIF Redundant Power Supply

Overview

Foundry Network’s External Redundant Power Supply (RPS2-EIF) can supply a maximum of 150 Watts of output power per port, a total of 600 Watts of backup power to four FasrIron devices in the event of an AC loss or failure of an internal power supply.

The system operates as a backup to a switch's internal power supply. If an internal power supply fails, the RPS will support the full load of the switch without affecting network operation.

The following devices are supported by the FastIron RPS2-EIF: Foundry FastIron LS624 and FastIron LS648.

Features and Benefits

•Supports four FastIron devices with 12V DC output

•Status LEDs located on the front panel

•AC line cord can draw power from a different supply circuit

•DC line cord provides backup power to the attached device

•Thermal overload protection prevents the RPS from overheating if a thermal overload occurs.

•Over-voltage protection shuts down an output channel if the voltage exceeds a preset threshold.

•Over-current protection shuts down the RPS if the output load exceeds a preset threshold.

•Short-circuit protection prevents the RPS from being damaged from a short circuit on any output channel.

•The power supply will operate under a no-load condition.

Front and Rear Panels

Four power indicators and one fan indicator are located on the RPS’s front panel. The AC supply and DC backup receptacles are located on the RPS’s rear panel.
