If your chassis has more than one switching module, you will see the progress check if you issue the show module command several times and view the status column each time.

The switching module goes through a testing and an initializing stage before displaying an ok status.

The following table describes the possible states in which a module can exist.

show module Output

Description

 

 

powered up

The hardware has electrical power. When the hardware is powered up, the

 

software begins booting.

 

 

testing

The module has established connection with the supervisor and the switching

 

module is performing bootup diagnostics.

 

 

initializing

The diagnostics have passed and the configuration is being downloaded.

 

 

failure

The switch detects a switching module failure on initialization and

 

automatically attempts to power-cycle the module three (3) times. After the

 

third attempt it continues to display a failed state.

 

 

ok

The switch is ready to be configured.

 

 

power-denied
