Power subsystem
The system transfers –54 VDC power from the power modules to the chassis
backplane and distributes it to all the cards through the backplane connectors.

Processor subsystem
Includes the active Route Switch Processor (RSP) card (and optional, redundant
RSP card, if installed).
Up to eight line cards in the Cisco ASR 9010 Router and Cisco ASR 9910 Router,
four line cards in the Cisco ASR 9006 Router and Cisco ASR 9906 Router, and
two line cards in the Cisco ASR 9904 Router.
The RSP and line cards are equipped with onboard processors. The
RSP downloads a copy of the Cisco software image to each line card
processor. The system uses an alphanumeric display on the active RSP
to display status and error messages, which can help in troubleshooting.
