Treatment of Newly Inserted Line Cards
After you insert a line card into the router, the software identifies the card and executes one of three actions, depending on the contents of the running configuration file:
•If the card is not described in the running configuration file, the system enters a basic configuration into the running configuration file. For example, if you insert a Gigabit Ethernet line card into slot 4, the system adds the following lines to the running configuration:
interface GigabitEthernet4/0/0
•If the card and slot are described in the running configuration file, the system applies that configuration to the card.
•If the card is of a type different from the one listed in the running configuration file, the software replaces the configuration with a basic configuration for the newly inserted card.
To find out the type of card that a slot is configured to use, enter the show running-config command.
Tip Most show commands support the pipe character and begin argument. For example, you can use the command show running-config | begin card to start the display of the running configuration file at the point where it lists the cards that are configured on your Cisco 10000 series router.
Preprovisioning Line Card Slots
The line card slot preprovisioning feature allows you to preprovision a Cisco 10000 series router line card slot to accept a particular line card. Using the card command, you can configure interfaces for a line card that is not yet inserted into the router chassis.
The line card slot preprovisioning feature allows you to plan for future configurations. Preprovisioning a line card slot downloads software to the line card slot for the line card you are planning to install. Preprovisioning allows you to prepare in advance a complete configuration for the line card, including items you normally need to configure after initially configuring the line card, such as PVCs under an ATM line card or VLANs under an Ethernet line card.
Personnel responsible for provisioning and setup operations can preprovision line card slots in the Cisco 10000 series router to accept a particular line card. When the functionality is needed, installers can then insert the card into the router chassis.
The following example preprovisions line card slot 2 to accept a 24-port E1/T1 line card operating in E1 mode:
Router(config)# card 2/0 24che1t1-1 mode e1
Changing the Provisioning of a Line Card Slot
Use the card command to change the provisioning of a line card slot. You can remove the old line card before or after using the card command to change the line card provisioning. The following example shows how to change the provisioning for line card slot 5 from the 1-Port Gigabit Ethernet Half-Height line card to the 4-Port OC3/STM-1 line card.
Router(config)# card 5/0 4oc3atm-1

Usage Guidelines
You must specify a line card slot and subslot, and the line card for which you want to preprovision the line card slot.
If you insert a line card into a line card slot that has been preprovisioned for a different line card, the line card reports a boot failure in an error message to the console. Output from the show ip interface brief command indicates that the line card remains in an initialized state.
You can specify a mode of operation for the 24-port E1/T1 line card. If you do not, the line card operates in the E1 mode.
Example
The following example preprovisions line card slot 2 to accept a 24-port E1/T1 line card operating in E1 mode:
Router(config)# card 2/0 24che1t1-1 mode e1
Resetting Line Cards
You can use the privileged EXEC mode hw-module command to reset a line card. For example:
Router# hw-module slot 2 reset
Resetting a line card effectively reloads the line card software onto the line card.
