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.
Caution
|
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.
|
Trouble
|
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.
