There is also a healthy LED labeled D2 on each DCB. This LED is
an indication of several things, including a healthy watchdog
between the adjacent board, and healthy DC voltages. The light will
go out if either of the DC voltages (except the 5V) drops too low, or
if the watchdog is absent for 10 consecutive samples. The watchdog
is annunciated every 1 ms. The DCB OK contact on the SCB
operates in parallel to the D2 LED. When D2 is on, DCB OK is
closed.
