state. For example, if the power consumption can be satisfied by power supply 1, then power supply 2 is put
into a standby state.
When you replace power supplies, do not mix power supply types in the FMC. Both power supplies must be
the same wattage and Cisco PID.
Caution
Power supply health monitoring notifies you if the power supply loses power or malfunctions so that redundancy
is lost. Check the power supply cables to make sure they are functioning. If they are and errors are still
occurring, replace the power supply.
