Viewing the State of a Module
Cisco MDS 9500 Series switches have two supervisor modules--one in slot 5 (sup-1) and one in slot 6
(sup-2). When the switch powers up and both supervisor modules come up together, the module that
enters the active mode is dependent on which of the two modules comes up first. The standby module
constantly monitors the active module. If the active module fails, the standby module takes over without
any impact to user traffic.
Switching Modules
Cisco MDS 9000 Family switches support any switching module in any non-supervisor slot. The
switching module obtains its image from the supervisor module.
The interfaces in each module are ready to be configured when the module displays an ok status.
Viewing the State of a Module
The switching module goes through a testing and an initializing stage before displaying an ok status.

Description
The hardware has electrical power. When the
hardware is powered up, the software begins
booting.
The module has established connection with the
supervisor and the switching module is
performing bootup diagnostics.
The diagnostics have completed successfully and
the configuration is being downloaded.
The switch detects a switching module failure
upon initialization and automatically attempts to
power-cycle the module three times. After the
third attempt it continues to display a failed state.
The switch is ready to be configured.
The switch detects insufficient power for a
switching module to power up.
This module is the active supervisor module and
the switch is ready to be configured.
This module is the standby supervisor module and
that the HA switchover mechanism is enabled.
This module is the standby supervisor module and
the warm switchover mechanism is enabled.
