M10i System Redundancy

 

You can configure the router for system redundancy by using three AC or four DC load-sharing, fully-redundant power supplies to distribute power to the other components.

AC System Redundancy

AC system redundancy requires three independent AC power outlets. If one power supply fails, the other two power supplies provide full power to the router's components indefinitely.

You can set up increased AC system redundancy by using four AC power supplies. In this case, two power supplies are powered from two AC outlets, and the other two power supplies use two AC outlets from a UPS battery-backed power source. This lets the router run during AC power outages for the amount of time that the UPS allows.

DC System Redundancy

DC system redundancy requires two power sources from feed A and two power sources from feed B. If one feed fails or is shut down for service, the other feed powers two DC power supplies and can provide full power to the router's components indefinitely.
