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.

[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.
