Replacing the redundant power supply
The redundant power supply offers fault tolerance and hot-swap capabilities.
However, if the power distribution board at the base of the power supply or
some other shared component fails, the entire power supply and its housing
must be replaced. A failure of a shared component is indicated by both power
supply status LEDs flashing and an audible alarm, or the system will fail to
power up.
