THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

The NPE-100, NPE-150, and NPE-200 consist of the following components:

• Reduced instruction set computing (RISC) microprocessor

–

The NPE-100 and NPE-150 have an R4700 microprocessor that operates at an internal clock speed of 150 MHz.

–

The NPE-200 has an R5000 microprocessor that operates at an internal clock speed of 200

MHz.

• System controller

The system controller provides hardware logic to interconnect the processor, DRAM, and the PCI-based system backplane bus. The NPE-150 and NPE-200 have a system controller that uses direct memory access (DMA) to transfer data between DRAM and packet SRAM on the network processing engine.

Chapter 1 NPE-100, NPE-150, and NPE-200 Overview

• Upgradable memory modules

The NPE-100, NPE-150, and NPE-200 use DRAM for storing routing tables, network accounting applications, packets of information in preparation for process switching, and packet buffering for SRAM overflow (except in the NPE-100, which contains no packet SRAM). The standard configuration is 32 MB, with up to 128 MB available through single in-line memory module (SIMM) upgrades.

• Packet SRAM for storing data packets

–

The NPE-100 does not have packet SRAM.

–

The NPE-150 has 1 MB of SRAM.

–

The NPE-200 has 4 MB of SRAM.

• Cache memory

The NPE-100, NPE-150, and NPE-200 have unified cache SRAM that functions as the secondary cache for the microprocessor. (The primary cache is within the microprocessor.)

• Two environmental sensors for monitoring the cooling air as it leaves the chassis

• Boot ROM for storing sufficient code for booting the Cisco IOS software on the NPE-200

NPE-100, NPE-150, and NPE-200 Description and Overview

Note The NPE-100 and NPE-150 use the boot ROM on the I/O controller.

System Management Functions

The network processing engines perform the following system management functions:

• Sending and receiving routing protocol updates

• Managing tables, caches, and buffers

• Monitoring interface and environmental status

• Providing Simple Network Management Protocol (SNMP) management through the console and

Telnet interface

• Accounting for and switching of data traffic

• Booting and reloading images

• Managing port adapters (including recognition and initialization during online insertion and

removal)

Terms and Acronyms

• Cache—Memory with fast access and small capacity used to temporarily store recently accessed

data; found either incorporated into the processor or near it.

• DIMM—dual in-line memory module

• DRAM—dynamic random-access memory

OL-4448-12

• Instruction and data cache—Instructions to the processor, and data on which the instructions work.

• Integrated cache—Cache that is built into the processor; sometimes referred to as internal cache.

Cache memory physically located outside the processor is not integrated, and is sometimes referred to as external cache.

NPE-100, NPE-150, and NPE-200 Memory Information

• OTP—one time programmable

• Primary, secondary, tertiary cache—Hierarchical cache memory storage based on the proximity of

the cache to the core of the processor. Primary cache is closest to the processor core and has the fastest access. Secondary cache has slower access than primary cache, but faster access than tertiary cache.

• RAM—random-access memory

• RISC—reduced instruction set computing

• ROM—read-only memory

• SIMM—single in-line memory module

• SDRAM—synchronous dynamic random-access memory

• SDRAM-fixed—SDRAM of a fixed size or quantity; can be replaced, but not upgraded

• SODIMM—small outline dual in-line memory module

• SRAM—static random-access memory

• Unified cache—Instruction cache and data cache are combined. For example, a processor may have

primary cache with separate instruction and data cache memory, but unified secondary cache.

NPE-100, NPE-150, and NPE-200 Memory Information

To determine the memory configuration of your NPE, use the show version command.

The following example shows an NPE-150 installed in a Cisco 7206 router:

Use the following sections for information about memory specifications and configurations for the NPE-100, NPE-150, and NPE-200.

Note To prevent DRAM errors in the NPE-100, NPE-150, or NPE-200, and to ensure that your system

initializes correctly at startup, DRAM bank 0 (socket U18 and U25, or U11 and U25) must contain no fewer than two SIMMs of the same type. You may also install two SIMMs of the same type in bank 1 (socket U4 and U12, or U42 and U52); however, bank 0 must always contain the two largest SIMMs.

The NPE-175 and NPE-225 consist of the following components:

• Reduced instruction set computing (RISC) microprocessor

–

The NPE-175 has an RM5270 microprocessor that operates at an internal clock speed of 200

MHz.

–

The NPE-225 has an RM5271 microprocessor that operates at an internal clock speed of 262

MHz.

• System controller

The system controller provides hardware logic to interconnect the processor, DRAM, and the PCI-based system backplane bus. The NPE-175 and NPE-225 have one system controller that provides processor access to the two midplane and single I/O controller peripheral component interconnect (PCI) buses. The system controller also allows port adapters—on either of the two midplane PCI buses—access to SDRAM.

• Upgradable memory modules

The NPE-175 and NPE-225 use SDRAM for providing code, data, and packet storage.

• Cache memory

The NPE-175 and NPE-225 have unified cache SRAM that functions as the secondary cache for the microprocessor. (The primary cache is within the microprocessor.)
