Status of the SCE 1000 After Abnormal Boot
This parameter determines whether the SCE 1000 returns to normal operational state after a
reboot caused by fatal error or abnormal shutdown. In general, it is desirable that the SCE 1000
resume operation, and as promptly as possible. However, in a redundant topology, a recovered
SCE 1000 may remain non-operational. In this case the platform that had been the backup and is
currently active will remain active.
The two options for this parameter are:
• Operational — The status of the SCE 1000 after abnormal boot is operational. The platform
automatically resumes functioning in the defined operational link bypass mode.
• Not Operational — The status of the SCE 1000 after abnormal boot is not operational. The
platform remains in the defined failure link bypass mode.
This option is to be used only in a redundant topology where a second, operational platform
exists.
Note
Default value = Operational for all non-redundant systems.
Must be explicitly configured for redundant topologies.

defined parameters. These values can be changed only via specific CLI commands.
[1]: In a redundant topology, it is also possible to configure admin status after abnormal boot to be
Not operational. In this case, though, the SCE 1000 would have to be manually reloaded in order
to resume full functionality.
