Route Switch Processor CardThe RSP card is the main control and switch fabric element in the Cisco ASR 9010 Router,
Cisco ASR 9006 Router, and Cisco ASR 9904 Router chassis. The RSP card provides system control,
packet switching, and timing control for the system. To provide redundancy, there can be two RSP cards
in the system, one as the active control RSP and the other as the standby RSP. The standby RSP takes
over all control functions should the active RSP fail.
Figure 2-6 shows the front panel connectors and indicators of the RSP card.
