Event
Cause
Enabling
Failed CGC Health
The Reader continuously monitors the CGC
health and forces a switchover if health fails.
Automatic
Failed Serial Lane
Controller Link
The Reader forces a switchover when an
enabled serial link from the LPM to the LC
has been interrupted. Usually a downed link
is due to external conditions.
Only the lack of OBU transactions in outgoing
messages to the LC allows a downed link to
be detected. To detect serial cable issues in
the absence of OBU transactions, the
operator must enable Heartbeat messages
Must enable Switchover on
Serial Link Down from
