If a model B power supply goes into shutdown, it remains turned off until the
fault condition is rectified. At that point, the power supply restarts itself,
except in the case of an overvoltage condition.
To recover from a shutdown caused by an overvoltage state, the AC line input
must be turned off for at least one second.
WARNING! A replacement AC power supply should
never be placed in an SFCS-1000 that already
contains a DC power supply, and vice-versa. If
these instructions are not heeded, there is a
risk of electrical shock, danger to personal
health, and serious damage to the equipment.
If the power supply needs to be replaced, please refer to Chapter 3, Hardware
Maintenance Procedures, for hot-swap information.
