PIC may result in limited packet loss in the active-active backhaul configuration.
• In a Cisco cBR without Supervisor redundancy, removing the Supervisor Card or Supervisor PIC results
in complete loss of service.
Caution
• Attach an ESD-preventive wrist strap to your wrist and connect the other end to the grounding lug
connected to the chassis.

• Close the tethered I/O door by pushing the door until it snaps into place on the spring-loaded ejector of
