A. General
(1) The ACD processor provides a Watchdog 'keep alive' signal within 1.2 s ± 0.2 s.
NOTE: HW watchdog triggers if it does not receive a periodic 'keep alive' signal'
within 1.6 s± 0.2 s from software running on the ACD Processor.
(2) If POST is interrupted by a power failure longer than the transparency period and for
sufficient time to cause brownout, the SDU restarts POST once power is restored.
(3) When a Secure ORT file is not present, the following values are used for the default start-
up ACD interface configuration:
(a) Ethernet port 3 configuration
1 If the SDU is strapped as SDU1, then Set the Ethernet port 3
configuration as follows:
a Enabled: 100 Base-T / Full Duplex
b Speed: Automatically negotiated
c Address: 172.30.3.11
d Gateway Address: 172.30.3.1
e Network Mask: 255.255.255.0
2 If the SDU is strapped as SDU2, then set the Ethernet port 3
configuration as follows:
a Enabled: 100 Base-T / Full Duplex
b Speed: Automatically negotiated
c Address: 172.30.3.12
d Gateway Address: 172.30.3.1
e Network Mask: 255.255.255.0
(4) The SDU performs an Air/Ground status determination.
(5) On application start-up, the SDU determines which of the following caused the SDU to
startup:
(a) Power Cycle.
1 External Reset Discrete asserted for greater than 0.5 seconds.
2 SW triggered BITE recovery,
3 SW triggered mode dependent (data load programming NVM variable
set, restricted test mode entry).
