Cisco 7200 VXR Installation and Configuration Guide
78-5469-04 B0
Chapter 1 Cisco 7200 VXR Product Overview
Field-Replaceable Units
Note Replacement instructions for removing and replacing FRUs are contained in separate documents that
accompany each FRU shipped from the factory. For example, if you need to replace an AC power supply
in your Cisco 7200 VXR router, refer to the 280-Watt AC-Input Power Supply Replacement Instructions
publication. Replacement instructions are also available on the Documentation CD-ROM and on
Cisco.com.
Network Processing Engine or Network Services Engine
The network processing engine or network services engine maintains and executes the system
management functions for Cisco 7200 VXR routers. Also, the network processing engine or network
services engine shares the system memory and environmental monitoring functions with the I/O
controller.
Because the NPE-G1 contains I/O functionality the Cisco 7200 VXR routers can operate with no I/O
controller with an NPE-G1 installed. With both an I/O controller and the NPE-G1 installed, the NPE-G1
enhances the I/O controller functionality.
Cisco 7200 VXR routers support eight versions of the network processing engine: NPE-G1, NPE-400,
NPE-300, NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100. These network processing engines
have the same functionality; however, their performance differs because of the microprocessor type and
the type of memory for packet data (SRAM and DRAM, or SDRAM) that each network processing
engine provides.
Cisco 7200 VXR routers also support the NSE-1, which consists of two modular boards: the processor
engine board and the networkcontroller board. The NSE-1 ParalleleXpress Forwarding (PXF) processor
works with the Route Processor to provide accelerated packet switching, as well as accelerated IP
Layer 3 feature processing.
Note Detailed instructions for removing and replacing the network processing engines or network services
engine are contained in the online Network Processing Engine and Network Services Engine Installation
and Configuration publication. It is also available on the Documentation CD-ROM and on Cisco.com.
The network processing engines and network services engine consist of the following components:
• Reduced instruction set computing (RISC) microprocessor
–
The NPE-G1 uses aBCM1250 microprocessor that operates at an internal clock speed of 700 MHz.
–
The NSE-1 uses an RM7000 microprocessor that operates at an internal clock speed of
262 MHz.
–
The NPE-400 uses an RM7000 microprocessor that operates at an internal clock speed of
350 MHz.
–
The NPE-300 uses an RM7000 microprocessor that operates at an internal clock speed of
262 MHz.
–
The NPE-225 has an RM5271 microprocessor that operates at an internal clock speed of
262 MHz.
–
The NPE-200 has an R5000 microprocessor that operates at an internal clock speed of
200 MHz.
–
The NPE-175 has an RM5270 microprocessor that operates at an internal clock speed of
200 MHz.
