    Each line card circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. When a line card slot is not in use, a blank line card must fill the empty slot to allow the router to conform Note to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the line cards.

  • Page 30: Handling Line Cards

    The Cisco 7304 router supports online insertion and removal (OIR) of line cards; therefore, you do not have to power down the router when removing and replacing a 6E3 line card on a Cisco 7304 router. The Cisco 7304 router also supports CLI-controlled OIR, which allows active data traffic to complete before the active interfaces are shut down.
