Reboot Only (Fully Automatic Recovery), page 11-12
This section specifies the procedure for recovery after a failure. The purpose of the recovery procedure
is to restore the system to fully functional status. After the recovery procedure, the behavior of the
system is the same as after installation.
A failed Cisco SCE platform may either recover automatically or be replaced (manual recovery).
Whether recovery is automatic or manual depends on the original cause of the failure:
•
Power failure—Manual or automatic recovery can be implemented.
•
Any failure resulting in a reboot—Manual or automatic recovery can be implemented (this is
configurable).
•
3-consecutive reboots within half an hour—Manual recovery only
•
Cascade ports link-failure—Automatic recovery when link revives.
•
Traffic link failure—Automatic recovery when link revives.
•
Failure in the communications with the SM—Automatic by SM decisions after connection is
re-established.
•
Hardware malfunction—Manual recovery, after replacing the malfunctioning Cisco SCE platform.
Replacing the Cisco SCE Platform (Manual Recovery)
This is done in two stages, first manual installation steps performed by the technician, and then
automatic configuration steps performed by the system.
