Remove and Replace a Power Supply
The chassis ships with two power supplies, which are redundant and hot-swappable. One is the active power
supply and the other is the standby power supply (1+1).
This chassis also supports cold redundancy. Depending on the power being drawn by the chassis, one power
supply might actively provide all power to the system while the remaining power supply is put into a standby
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 chassis. Both power supplies must
be the same wattage and Cisco PID.
