#7 (D1) Heartbeat LED Indicator
Heartbeat LED (D1), located on the front
side of the AOC-SIMSO(+) card, indicates
the functionality and activity of the add-on
card. The blinking of the Heartbeat LED
indicates that the AOC-SIMSO(+) is ac-
tive. However, when the Linux OS and
the drivers are being loaded after each
AC power-on or reset, the Heartbeat
LED is off for about a minute. Then, the
Heartbeat LED will be on again to indicate
that the AOC-SIMSO(+) is active. See the
table on the right for details.
