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.
