Hyperactivity: Currently, the common circuit pack is considered “hyperactive” if the circuit pack sends 200 uplink messages in a 10-second period. An alarm is issued when the limit reaches 400. When the limit reaches 500 uplink messages in 10 seconds, the board is taken out of service.

Port Administration: In Administration Without Hardware (AWOH), the switch allows administration of up to 8 ports in any of the first 12 ports. If the port type later reported by the board does not match the existing type, the switch assumes it to be a MAPD board with a different configuration and rejects the board.
