Table 6-4: Switchover triggers
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
Switchover panel on General
page.
Must set LC Retry Timeout from
LC Serial panel on Lane
Controller page.
Set Heartbeat messages from LC
Serial panel on Lane Controller
page.
