CAUTION:
The command init-sys:all may affect service. It should
never be used on an in-service system. It should be used
only after a shelf has been equipped to reset all
provisionable parameters and cross-connections to their
default values.
NOTE:
An inconsistent DCC values alarm will occur when the
init-sys:all command is executed because "fecom"
becomes enabled again. To clear the alarm, use the
set-fecom:address:com=disable to disable the DCC.
Use the init-sys:all command to initialize all provisionable
parameters to their original default values.
