Component Failure Recovery
The S2A contains redundant and hot-swappable fans and power supplies. A single component
failure, therefore, will not shut down the system. In the unlikely event of a component failure,
you can replace the failed component while the S2A is running. The replaced component will
automatically be returned to service in the system.
4.1.1.1
Power Supply Failure
A power supply failure message will be displayed on your console if a power supply fails. The
status LED on the power supply module will also turn red
.
NOTE :
The S2A should not be operated with any open slots for more than 15 minutes. Make sure
you have the replacement power supply available before removing the failed module.
