Field-Replaceable Units

•CompactFlash Disks, Flash Disks, and PC Cards, page 1-52

•Rack-Mount and Cable-Management Kit, page 1-53

Note Replacement instructions for removing and replacing FRUs are contained in separate online documents. For example, if you need to replace an AC power supply in your Cisco 7200 VXR router, refer to the 280-WattAC-Input Power Supply Replacement Instructions publication. Replacement instructions are available on the Documentation DVD 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 and NPE-G2 contain I/O functionality, the Cisco 7200 VXR routers can operate with no I/O controller with an NPE-G1 or NPE-G2 installed. With both an I/O controller and the NPE-G1 or NPE-G2 installed, the NPE-G1 or NPE-G2 enhances the I/O controller functionality.

Cisco 7200 VXR routers support nine versions of the network processing engine: NPE-G2, 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 network controller board. The NSE-1 Parallel eXpress 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 available on the Documentation DVD 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-G2 uses a Motorola Freescale 7448 microprocessor that operates at an internal clock speed of 1.67 GHz.

–The NPE-G1 uses a BCM 1250 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.
