EPS-C2 Redundant Power System
The EPS-C2 is an external power supply system that supplies redundant power to switches.
It is a standalone unit that can be rack mounted in a regular 19-inch rack system. The EPS-C2 can be populated with up to three 750 W PoE AC PSUs (power supply units) to provide a total redundant power budget of up to 2040 W. The redundant power supply system can connect up to five switches to actively provide power to all five if needed.
The EPS-C2 redundant power system consists of the EPS-C2 chassis (Model 10936) plus one, two, or three installed 750 W AC power supplies (Model 10931).
The EPS-C2 system provides redundant power for up to five switches. Redundant power connectors on the rear panel of the EPS-C2 chassis are specific to the supported switch type; a selection switch toggles between the connector type.
The 750 W AC PoE PSU used on the EPS-C2 has two power rails: 12V and PoE. These two power rails are independent. If the PoE rail overloads, it will shut down all PoE but the 12V rail will continue to function. If the 12V rail overloads, the 12V shuts down and the PoE rail will continue to function.
The following table lists the power capability in watts of the EPS-C2 based on the number of installed PSUs. Check the power requirements of your switches to determine how many PSUs you need to install into the EPS-C2 chassis.
