12. After you remove each MIC, immediately place it on an antistatic mat or in an
electrostatic bag.
13. If you are not reinstalling an MPC into the emptied line card slots within a short time,
install a blank DPC panel over each slot to maintain proper airflow in the card cage.
CAUTION: After removing an MPC from the chassis, wait at least 30
seconds before reinserting it or inserting an MPC into a different slot.
