Remove and Replace a Power Supply
Two power supplies ship with the chassis; they are redundant and hot-swappable. One is the active power
supply and the other is the standby power supply (1+1).
The S195 ships with one power supply, but you can add another one for redundancy.
Note
The 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.
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.
