RSP16—Cisco 7507, Cisco 7507-MX, Cisco 7513, and Cisco 7513-MX
The RSP16 is the latest-generation, main system processor module for the Cisco 7500 series routers.
The RSP16 supports the high system availability (HSA) feature, which allows two RSP16s (or an RSP16
and an RSP8) to be used in a Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX router. The
redundancy increases system availability during planned and unplanned network outages..
The RSP16 also supports high availability (HA), a series of features that operates similarly to HSA, but
which further minimizes system downtime. (HSA is the system default.)
The RSP16 is not available as an upgrade to an existing RSP, but supports the VIP2, VIP4, and new
VIP6-80. The RSP16 does not support legacy interface processors, except for the CIP2, GEIP, GEIP+,
FEIP2-DSW-2TX, FEIP2-DSW-2FX, SRPIP, CX-CIP2-ECA1 and ECA2. The RSP16 contains the
central processing unit (CPU) and most of the memory components for the router. The Cisco IOS
software images reside in Flash memory, located as follows on the RSP16:
•
In the form of a single in-line memory module (SIMM) (U1 in
Figure 2
)
•
Up to two Flash Disks that insert in the two PC Card slots (slot 0 and slot 1)
