The Status column in the output should display an ok status for switching modules and an active or
standby (or HA-standby) status for supervisor modules. If the status is either ok or active, you can
continue with your configuration.
Note A standby supervisor module reflects the HA-standby status if the HA switchover mechanism is enabled.
If the warm switchover mechanism is enabled, the standby supervisor module reflects the standby status.
For information about the states through which a switching module progresses, see the “Checking the
State of a Module” section on page 6-16.
Checking the State of a Module
If your chassis has more than one I/O module, you can check the progress by repeatedly using the show
module command and viewing the Status column each time.
The I/O module goes through a testing and an initializing stage before displaying an ok status. Table 6-8
describes the possible states in which a module can exist.
