power consumption with dual power supply

Hi,

I need to know how dual power supply works, I mean, when you have two power supplies in a router if both of them are working at the same time, or if one of them is working while the other one only begin to work when the first one stops.

And if both of them are working at the same time, what is the power consumption, the same as if only one of them was working?

Thanks

The implementation details can potentially differ per product category but usually the following is applicable:

  1. The product provides configurable power redundancy modes and choosing a mode dictates whether load will be shared across supplies or whether a particular supply will be dedicated for redundancy.
  2. If both (or more) supplies are working at the same time then both share the power load.
  3. The actual power consumption depends on the power required to run the installed components and is the same whether you use power supplies in redundant or power sharing mode.
