4.2.1Component Failure Recovery

The controller contains redundant and hot-swappable fans and power supply units. A single component failure, therefore, will not shut down the system. However, in the unlikely event of component failure, you can replace the failed component while the controller is running. The replaced component will automatically be returned to service once the component has been installed and booted up.

4.2.1.1Power 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 turn off (Figure 4–4).
