The RSP2 supports the VIP2 and the VIP4 in the Cisco 7505, Cisco 7507, and the Cisco 7513. (See
Figure 1 and Figure 2.)
The RSP2 supports the VIP2 and VIP4 in the Cisco 7000 series routers, and the VIP2, VIP4, and the
VIP6-80 in the Cisco 7505, Cisco 7507, and the Cisco 7513 routers. The RSP2 is not supported on the
Cisco 7507-MX or the Cisco 7513-MX routers. The RSP2 is not available as an upgrade from an
RSP700, or an RSP1. You cannot upgrade to an RSP4/4+, RSP8, or RSP16 from the RSP2.
The RSP2 contains the central processing unit (CPU) and most of the memory components for the router.
The Cisco IOS software images reside in Flash memory, which is located on the RSP2:
• In the form of a single in-line memory module (SIMM) (U1 in Figure 2)
• On up to two PC Cards (called Flash memory cards) that insert in the two PC Card slots (slot 0 and
slot 1) in the two PC Card slots (slot 0 and slot 1).
Note For specific Cisco IOS software release compatibility, refer to the “System Software” section on page 8
and to the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl.
Storing the IOS software images in Flash memory enables you to download and boot from upgraded
Cisco IOS software images remotely or from software images resident in the RSP2 Flash memory,
without having to remove and replace read-only memory (ROM) devices.
The RSP2 also contains:
• Most of the additional memory components used by the system, including 16-MB onboard Flash
memory and up to two Flash memory cards (16-MB, or 20-MB Flash memory card, with 20-MB
being the shipping default).
• Air-temperature sensors for environmental monitoring. (All of the logic for the environmental
monitoring functions is contained on the router interface card.)
In addition to running the system software from DRAM, the RSP2 contains and executes the following
management functions that control the system:
• Sending and receiving routing protocol updates
• Managing tables and caches
• Monitoring interface and environmental status
