Supported RSP Features
The RSP provides the following features on the Cisco router:
• Centralized data plane, timing, and control plane functions for the system
• High-level control of interface modules
• Management functionalities for the router
• Control plane (host) CPU and associated memory in which IOS-XE and platform control software runs
• Nonvolatile memory for storage of software images, configurations, and system files
• Enabling and monitoring the health and presence of fan trays, interface modules, and power supplies
• Field replacement and hot-swap capabilities
RSP Redundancy
The Cisco ASR 903 Router chassis includes two RSP slots to allow for redundant RSPs. When the router uses
redundant RSPs, one RSP operates in the active mode and the other operates in the hot standby mode. Removal
or failure of the active RSP results in an automatic switchover to the standby RSP.
If you are using redundant RSPs, both the RSPs must be of the same type because a mixed configuration of
two different RSP types is not supported.
