Cisco 7000 Hardware Installation And Maintenance page 36

Physical Description
but with improved performance on a single processor module. The RSP7000 contains the central
processing unit (CPU) and most of the memory components for the Cisco 7000 series routers. You
must install the RSP7000 in the 7000 RSP slot (slot 5 in the Cisco 7000).
Note
(Cisco IOS) Release 10.3(9) or later. For the RSP7000 to operate properly, the Cisco 7000 chassis
must also be configured with the 7000 Series Chassis Interface (RSP7000CI), which installs in the
7000 CI slot (slot 6 in the Cisco 7000).
The Cisco IOS images reside in Flash memory, which is located either on the RSP7000, in the form
of a single in-line memory module (SIMM), or on up to two Personal Computer Memory Card
International Association (PCMCIA) cards (called Flash memory cards) that insert in the two
PCMCIA slots (slot 0 and slot 1) on the front of the RSP7000. (See Figure 1-9.)
Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded
Cisco IOS images remotely or from software images resident in the RSP7000 Flash memory,
without having to remove and replace read-only memory (ROM) devices.
Note
remove the RSP7000 to configure jumpers. There are no user-configurable jumpers on the RSP7000.
The RSP7000 contains the following components:
•
•
•
•
In addition to the system software, the RSP7000 contains and executes the following management
functions that control the system:
•
•
•
•
The high-speed switching section of the RSP7000 communicates with and controls the interface
processors on the high-speed CxBus. This switching section decides the destination of a packet and
switches it accordingly. The RSP7000 uses a 16-million-instructions-per-second (mips) processor to
provide high-speed, autonomous switching and routing.

The RSP7000 requires that your Cisco 7000 is running Cisco Internetwork Operating System
The RSP7000 uses a software-controlled configuration register, so it is not necessary to
Mips R4600 Reduced Instruction Set Computing (RISC) processor, used for the CPU (The CPU
runs at an external clock speed of 50 MHz and an internal clock speed of 100 MHz.)
A bank of hardware (Media Access Control [MAC]–layer) addresses for the interface ports
Most of the memory components used by the system, including onboard Flash
Air-temperature sensors for environmental monitoring (All of the logic for the environmental
monitoring functions is contained on the chassis interface card.)
Sending and receiving routing protocol updates
Managing tables and caches
Monitoring interface and environmental status
