Chapter 1 Cisco 7500 Series Product Overview
•
In addition to running the system software from DRAM, the RSP16 contains and executes the following
management functions that control the system:
•
•
•
•
The high-speed switching section of the RSP16 communicates with and controls the interface processors
on the high-speed CyBus. This switching section of the RSP16 decides the destination of a packet and
switches it based on that decision.
A bank of hardware MAC-layer addresses for the interface ports is contained in an NVRAM device on
Note
the router backplane.
Following are chassis slot requirements for ensuring RSP16 compatibility.

Air-temperature sensors for environmental monitoring. (All of the logic for the environmental
monitoring functions is contained on the router interface card.)
Sending and receiving routing protocol updates
Managing tables and caches
Monitoring interface and environmental status
Providing Simple Network Management Protocol (SNMP) management and the interface between
the console and Telnet
You have no restrictions on installing an RSP16 in a Cisco 7505, however; the Cisco 7505 does not
support the HSA or the HA features.
You have no restrictions on installing an RSP16 in a Cisco 7507 or Cisco 7507-MX provided that
you install the RSP16 in slot 2, slot 3, or both. With the HSA or HA features enabled, you will install
an RSP16 (or an RSP8 and an RSP16) in both RSP slots.
You have no restrictions on installing an RSP16 in a Cisco 7513 or Cisco 7513-MX provided that
you install the RSP16 in slot 6, slot 7, or both. With the HSA or HA features enabled, you will install
an RSP16 (or an RSP8 and an RSP16) in both RSP slots.
It is assumed that if you install two RSP16s (or an RSP8 and an RSP16) in the Cisco 7507, Cisco
7507-MX, Cisco 7513, or Cisco 7513-MX, you plan to enable and configure the HSA or HA features
