10.1.1.
(X101) Power Input Connector
Table 7: (X101) Power Input Connector
If any of the supply voltages drops below the allowed operating level longer than the
specified hold-up time, all the supply voltages should be shut down and left OFF for a time
long enough to allow the internal board voltages to discharge sufficiently.
If the OFF time is not observed, parts of the board or attached peripherals may work
incorrectly or even suffer a reduction of MTBF.
The minimum OFF time depends on the implemented PSU model and other electrical factors
and needs to be measured individually for each case.
10.1.2.
