Initializat
ion Sequence
Each line mod
ule is initialized independently. As a result, the CLI o n the SRP
module can become available before the line modules have completed initialization.
Commands relating to a line module might fail if the module has not completed
initializa
tion. You can use the show version comma n d to display line module
status. Do not enter commands for a line m od ule until its state is listed as online.
