I would like to understand how two redundant power supplies work on a 4507R switch.
If I configure the switch to have two redundant power supplies (power redundancy-mode redundant) I believe only one power supply will work, this is, only onw power supply will be drawing the power to the modules and the other power supply is just waiting to as a backup if necessary but not drawing power to the chassis. In other words only one power supply holds the whole load or both power supplies balance the load? correct me if I'm wrong!!
If only one the power supplies hold the complete load how do I know which power supply is the one providing the power??
