Using IOC Module Pre-Configuration, you can configure a slot for an IOC Module before you insert the module in the chassis. By specifying the slot and module type, all configuration at the slot or port level become available for that slot. You can issue configuration commands for a specific slot before you insert an IOC Module in that slot.

When you insert the IOC Module that matches the pre-configured module type in the specified slot, all configuration related to that slot is applied, and pre-configuration loads on the IOC Module automatically. However, if the module type of the inserted IOC Module does not match the module type of the IOC Module Pre-Configuration, then the IOC module functionality depends on the following card lock configurations:

• If the card lock option is enabled, the inserted IOC Module is rejected and does not boot up. Only modules that are of same type as the IOC Module Pre-Configuration type for the slot are able to boot up on that slot. The output of the show-sys-info command displays the operational status of the inserted module as down-Mismatch.
• If the card lock option is disabled, existing configuration is removed on that slot and a new IOC Module is accepted and boots up with default configuration.

When you remove an IOC Module from the chassis, all configuration on that slot is still available because the module was automatically pre-configured on that slot. You can view the configuration for the module by using the show sys-info card command. You can also change the configuration for an IOC Module that has been removed from the chassis. When you save the configuration, the configuration for all slots is saved regardless of which modules are plugged into the chassis.
