Replacing a line card

You can remove a line card without powering it off. However, doing so will not remove the configuration. When you replace a card with a different type, you must first remove the configuration and then reconfigure the slot for the new line card type.

Install a new line card only if it is supported by the firmware running in the chassis. Inserting a line card into a chassis running firmware that does not support the line card may result in unexpected behavior.

Complete the following steps to replace a line card.

Note Icon
Removing the configuration requires the card to be powered off.
  1. Power off the line card by issuing the power-off linecard command followed by the slot number.
  2. Enter the configure terminal command to enter global configuration mode.
  3. Enter the rbridge-id rbridge-id command to enter RBridge ID configuration mode.
  4. Enter the no linecard slot_number command to clear the slot configuration.
  5. Remove the line card.
  6. Enter the linecard slot_number command followed by a question mark (?) to display the line card menu.
  7. Select a line card type and enter the linecard slot_number linecard_type command.
  8. Enter the exit command twice to return to privileged EXEC mode.
  9. Insert the new line card into the configured slot.
  10. Enter the power-on linecard command to power on the line card.
  11. Save the configuration persistently by issuing the copy running-config startup-config command after the line card reaches the online state.
  12. Verify the configuration with the show running-config linecard linecard command.
