Role of the Standby RSP
The second RSP to boot in a redundant pair automatically becomes the standby RSP. While the active RSP
manages the system and communicates with the user interface, the standby RSP maintains a complete backup
of the software and configurations for all cards in the system. If the active RSP fails or goes off line for any
reason, the standby RSP immediately takes control of the system.
