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.

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.

NPE-G1 Description and Overview

This section contains information about the NPE-G1 components and the system management functions. The NPE-G1 is the first net

processing engine for the Cisco 7200 VXR routers and Cisco uBR7200 series routers to provide the functionality of both a network processing engine and I/O controller. If used without an I/O controller, an I/O controller blank panel must be in place.

While its design provides I/O controller functionality, it can also work with any I/O controller supported in the Cisco 7200 VXR routers and Cisco I/O controller, provides the bootflash and NVRAM that the Cisco

Note An I/O controller can be used with the NPE-G1, but an I/O controller is not necessary for system

functionality. Installing an I/O controller in a chassis with the NPE-G1 activates the console and auxiliary ports on the I/O controller and automatically disables the console and auxiliary ports on the NPE-G1. However, you can still use the CompactFlash Disk slots and Ethernet ports on both the NPE-G1 and I/O controller when both cards are installed.

Three Gigabit Ethernet interfaces (six ports: three GBIC [optical] and three RJ-45s [copper]). Any three ports are available at the same time and are linked directly to the BCM1250 system; therefore the interfaces are not charged bandwidth points.

CompactFlash Disk for storing the default Cisco IOS software image. The CompactFlash Disk slot can be used whether or not an I/O controller is in the router.

Auxiliary port with full data terminal equipment (DTE) functionality. (Functional when an I/O controller is not present. If an I/O controller is present, its auxiliary port is the default port.)

Console port with full data communications equipment (DCE) functionality. (Functional when an I/O controller is not present. If an I/O controller is present, its console port is the default port.)

Boot ROM for storing sufficient code for booting the Cisco IOS software.

Flash memory for storing the boot helper (boot loader) image. (The boot helper image comes installed on the NPE-G1.) If an I/O controller is present, its flash memory is no longer available.

NVRAM for storing the system configuration and environmental monitoring logs. NVRAM uses lithium batteries to maintain its contents when disconnected from power. If an I/O controller is present, its NVRAM memory is no longer available.

Upgradable memory modules

• A total of three ports on any of the three interfaces (0/1, 0/2, or 0/3) can be used at any one time; for

example, 0/1 GBIC, 0/2 GBIC, and 0/3 RJ-45.

• The port numbering for the interfaces on the NPE-G1 start with 0/1 and not with 0/0, as is typical

for other interface cards. This is to avoid conflicts with the Ethernet and FastEthernet ports on an I/O controller, if it is also installed.

CompactFlash Disks are smaller in size than Type 2 Flash Disks but provide the same Attachment (ATA) interface and equivalent functionality. This interface complies with the ANSI ATA Interface Document X3T13.1153 D Rev. space.

The CompactFlash Disk has controller circuitry that allows it to emulate a hard disk and automatically maps out bad blocks and performs automatic block erasure. The CompactFlash Disk also provides the capability to allocate noncontiguous sectors, which eliminates the need for the squeeze command (which was required with older-style linear flash memory cards to recover the space used by deleted files).

The CompactFlash Disk also supports the Cisco IOS File System feature, which provides a single interface to all of the router’s file systems, including the Flash Disks and flash memory, as well as network file systems such as File Transfer Protocol (FTP) and Trivial FTP (TFTP) servers.

To install a CompactFlash Disk in the CompactFlash Disk slot, complete the following steps.

Step 1 Attach an ESD wrist or ankle strap, connecting the equipment end of the strap to an unfinished chassis

surface.

Step 2 Orient the CompactFlash Disk so that its connector end faces the appropriate slot. (See 1 in Figure 5-4.)

NPE-G1 Description and Overview

• The RJ-45 ports and GBIC ports are both reported in software as GigabitEthernet 0/1,

GigabitEthernet 0/2, and GigabitEthernet 0/3. Only one of the pair of interface ports can be used at a time; for example, GBIC GigabitEthernet 0/2 or RJ-45 GigabitEthernet 0/2.

• The I/O controller GE/E interface reports GigabitEthernet 0/0 and Ethernet 0/0, and the I/O

is off.

• With the NPE-G1 and an I/O controller both installed, the I/O controller functionality on the

NPE-G1 is shared with that of the I/O controller.

• When both an NPE-G1 and an I/O controller are installed, the flash memory and NVRAM of the

NPE-G1 are enabled and the flash memory and NVRAM on the I/O controller are no longer accessible.

• The console and auxiliary ports on the NPE-G1 are disabled by Cisco IOS when an I/O controller is

present; the console and auxiliary ports on the I/O controller are active.

• Console port messages can be routed to the auxiliary port on either the NPE-G1 or on the I/O

controller.

• The default media is the RJ-45 port. To change the media type, use the media-type command.

• Only the port selected by the media-type command is active. A cable attached to the other of the

RJ-45 and GBIC pair will be ignored. For example, if GBIC GigabitEthernet 0/2 is selected using the media-type command, RJ-45 GigabitEthernet 0/2 is ignored, even if a cable is attached to RJ-45 0/2.

NPE-G1 Description and Overview

• The NPE-G1 uses no bandwidth points, and when used with any I/O controller, the I/O controller

also uses no bandwidth points. None of the Gigabit Ethernet interfaces on the NPE-G1 use bandwidth points.

• The CompactFlash Disk on the NPE-G1 is available at all times, with or without an I/O controller

installed. The CompactFlash Disk is always addressed as the disk2 device, to avoid conflicts with the disk0 and disk1 devices on the I/O controller, if the I/O controller is also installed.

Note The Gigabit Ethernet interfaces on the NPE-G1 do not support the Inter-Switch Link (ISL) VLAN

encapsulation protocol. We recommend that customers use the IEEE 802.1Q VLAN encapsulation protocol as an alternative. Where an application requires the use of ISL, this can be provided by the Fast Ethernet or Gigabit Ethernet port adapters or I/O controllers.

System Management Functions

The NPE-G1 performs the following system management functions:

• Sending and receiving routing protocol updates

• Managing tables, caches, and buffers

• Monitoring interface and environmental status

Chapter 5 NPE-G1 Overview

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

2. A mode-conditioning patch cord is required. When using the WS-G5486 or GBIC-LX/LH with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC and the MMF cable on both the transmit and the receive ends of the link when link distances are greater than 984 very short link distances (tens of meters). The result could be an elevated bit error rate (BER).

Mode-Conditioning Patch Cord Description

A mode-conditioning patch cord can be used with the WS-G5486= or GBIC-LX/LH= to allow reliable laser transmission between the single-mode laser source on the GBIC and a multimode optical fiber cable.

When an unconditioned laser source designed for operation on single-mode optical fiber is directly coupled to a multimode optical fiber cable, an effect known as differential mode delay (DMD) might result in a degradation of the modal bandwidth of the optical fiber cable.

This degradation results in a decrease in the link span (the distance between a transmitter and a receiver) that can be supported reliably. The effect of DMD can be overcome by conditioning the launch characteristics of a laser source. A practical means of performing this conditioning is to use a device called a mode-conditioning patch cord.

A mode-conditioning patch cord is an optical fiber cable assembly that consists of a pair of optical fibers terminated with connector hardware. Specifically, the mode-conditioning patch cord is composed of a single-mode optical fiber permanently coupled off-center (see Offset in multimode optical fiber. Figure 5-11 shows a diagram of the mode-conditioning patch cord assembly.

Connection Equipment and Specifications

The mode-conditioning patch cord assembly is composed of duplex optical fibers, including a single-mode-to-multimode offset launch fiber connected to the transmitter, and a second conventional graded-index multimode optical fiber connected to the receiver. The use of a plug-to-plug patch cord maximizes the power budget of multimode 1000BASELX and 1000BASELH links.

The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center, which is accomplished by using the mode-conditioning patch cord. At the output of the patch cord, the WS-G5486 or GBIC-LX/LH is compliant with the IEEE

802.3z standard for 1000BASELX.

Console and Auxiliary Port Connection Equipment

The NPE-G1 has a DCE-mode console port for connecting a console terminal, and a DTE-mode auxiliary port for connecting a modem or other DCE device (such as a CSU/DSU or other router) to your router. However, with an I/O controller also installed in the router, the default console and auxiliary ports are on the I/O controller, and you cannot access the console and auxiliary ports on the NPE-G1.

Note Both the console and the auxiliary ports are asynchronous serial ports; any devices connected to these

ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

The NPE-G1 uses RJ-45 media for console port and auxiliary port connections.

Before connecting a terminal to the console port, configure the terminal to match the router console port as follows: 9600 baud, 8 data bits, no parity, 2 stop bits (9600 8N2). After you establish normal router operation, you can disconnect the terminal.

Like the NPE-G1, the NPE-G2 provides the functionality of both a network processing engine and I/O controller. If used without an I/O controller, an I/O controller blank panel must be in place.

While its design provides I/O controller functionality, it can also work with any I/O controller supported in the Cisco 7200 VXR routers or Cisco uBR7200 series routers. The NPE-G2, when installed with an I/O controller, provides the bootflash and NVRAM that the Cisco

Note An I/O controller can be used with the NPE-G2, but an I/O controller is not necessary for system

functionality. Installing an I/O controller in a chassis with the NPE-G2 activates the console and auxiliary ports on the I/O controller and automatically disables the console and auxiliary ports on the NPE-G2. However, you can still use the CompactFlash Disk slots and Ethernet ports on both the NPE-G2 and I/O controller when both cards are installed.

The NPE-G2 maintains and executes the system management functions for the Cisco 7200 VXR routers and Cisco functions. The NPE-G2 consists of one board with multiple interfaces.

The NPE-G2 can be used with the Port Adapter Jacket Card installed in the I/O controller slot. If you are upgrading to an NPE-G2 and Port Adapter Jacket Card at the same time, see the Por t A d apter Jacket Card Installation Guide for information about the order of installation of both the NPE-G2 and the Port Adapter Jacket Card.

Note An I/O controller can be used with the NPE-G2, but an I/O controller is not necessary for

system functionality. Installing an I/O controller in a chassis with the NPE-G2 activates the console and auxiliary ports on the I/O controller and automatically disables the console and auxiliary ports on the NPE-G2. However, you can still use the Compact Flash Disk slots and Ethernet ports on both the NPE-G2 and I/O controller when both cards are installed.

The three interfaces on the NPE-G2 consist of three small form-factor (SFP) Gigabit Ethernet ports and three 10/100/1000 Fast Ethernet/Gigabit Ethernet ports. The rules for using these ports are:

• Only one port per interface can be used at any one time. For example, for interface

• A total of three ports on any of the three interfaces (0/1, 0/2, or 0/3) can be used at any one time; for

example, 0/1 SFP, 0/2 SFP, and 0/3 RJ-45.

Table 6-5 for USB Flash memory module product options and

The NPE-G2 includes USB ports that can be used with Cisco USB Flash memory modules or with the Aladdin USB eToken Pro key. These USB devices can be used with the NPE-G2 for the following functions:

• The USB eToken Pro key by Aladdin Knowledge Systems provides a secure means to store and

deploy information, such as a bootstrap configuration or VPN credentials, separate from the router chassis. The USB eToken uses smart card technology to protect a small area of memory and grants access using a personal identification number (PIN). When IP Security (IPSec) VPN credentials are stored on the USB eToken, they are safely external to the router. When the USB eToken is inserted in a USB port, the router can pass the PIN and unlock it, retrieving the credentials and copying them into running memory. When the USB eToken is removed, the router will erase the credentials from running memory, ensuring that they cannot be retrieved from the router itself.

Note For more information about the USB eToken Pro key by Aladdin Knowledge Systems, see

the Aladdin website at www.aladdin.com/etoken/cisco.

• The Cisco USB Flash memory module can be used to store an image or configuration file like a

CompactFlash Disk. Unlike the USB eToken, the Cisco USB Flash memory module is nonsecure. See

Table 6-5 for available USB Flash memory module configurations and product numbers.

Note The Cisco USB Flash memory module cannot be used to boot the router. The USB drivers

exist only in Cisco IOS software, not ROM Monitor mode (ROMmon). As a result, a Cisco IOS image must be booted to load the drivers; only then can files be copied to and from the USB Flash memory module.

0/2, and GigabitEthernet 0/3. Only one of the pair of interface ports can be used at a time; for example, SFP GigabitEthernet 0/2 or RJ-45 GigabitEthernet 0/2.

• The I/O controller GE/E interface reports GigabitEthernet 0/0 and Ethernet 0/0, and the I/O

controller 2FE/E interface reports FastEthernet

“Copying the Configuration File” section on page 7-4 in Chapter 7, “NPE-G1

0/0 and FastEthernet 0/1.

• If the RJ-45 port is in use, the EN (Enable) LED is on. If the SFP port is in use, the EN (Enable)

LED is off.

• With the NPE-G2 and an I/O controller both installed, the I/O controller functionality on the

NPE-G2 is shared with that of the I/O controller.

• When both an NPE-G2 and an I/O controller are installed, the flash memory and NVRAM of the

NPE-G2 are enabled and the flash memory

• and NVRAM on the I/O controller are no longer accessible.

• The console and auxiliary ports on the NPE-G2 are disabled by Cisco IOS when an I/O controller is

present; the console and auxiliary ports on the I/O controller are active.

• Console port messages can be routed to the auxiliary port on either the NPE-G2 or on the I/O

controller.

• The default media is the RJ-45 port. To change the media type, use the media-type command.

• Only the port selected by the media-type command is active. A cable attached to the other of the

RJ-45 and SFP module pair will be ignored. For example, if SFP port GigabitEthernet 0/2 is selected using the media-type command, RJ-45 GigabitEthernet 0/2 is ignored, even if a cable is attached to RJ-45

0/2.

• The NPE-G2 uses no bandwidth points, and when used with any I/O controller, the I/O controller

also uses no bandwidth points. None of the Gigabit Ethernet interfaces on the NPE-G2 use bandwidth points.

• The CompactFlash Disk on the NPE-G2 is available at all times, with or without an I/O controller

installed. The CompactFlash Disk is always addressed as the disk2 device, to avoid conflicts with the disk0 and disk1 devices on the I/O controller, if the I/O controller is also installed.

• USB Flash memory modules are available for data storage, with or without an I/O controller

installed.

The NPE-G2 supports single Gigabit Ethernet interfaces based on SFP technology. The following SFP modules are supported by the NPE-G2:

• 100BASE-FX SFP—The SFP-GE-F=, 100BASE-FX SFP module is a hot-swappable device that

• 1000BASE-LX/LH SFP—The SFP-GE-L=, 1000BASE-LX/LH SFP module operates on ordinary

Single-mode fiber-optic: LC

plugs into a Gigabit Ethernet SFP port. It provides full-duplex 100-Mbps connectivity between switches over multimode fiber (MMF) infrastructures. The 100BASE-FX SFP operates on ordinary MMF optical link spans of up to 6562 ft (2 km) in length. Customers implementing Cisco 100BASE-FX SFP can use 1000BASE-X SFP modules in the future (including SX, LH/LX, ZX, and coarse wavelength-division multiplexing SFP modules).

single-mode fiber-optic link spans of up to 32,808 ft (10,000 m) in length.

• 1000BASE-SX SFP—The SFP-GE-S=, 1000BASE-SX SFP module operates on ordinary

multimode fiber-optic link spans of up to 1804 ft (550 m) in length.

• 1000BASE-ZX SFP—The SFP-GE-Z=, 1000BASE-ZX SFP module operates on ordinary single

mode fiber-optic link spans of up to 43.5 miles (70 km) in length. Link spans of up to 62.1 miles (100 km) are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. The SFP module provides an optical link budget of 23 dB—the precise link span length depends on multiple factors such as fiber quality, number of splices, and connectors.

When shorter distances of single-mode fiber are used, it may be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. A 5-decibel (dB) or 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the SFP-GE-Z= at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km).

Note Optical fiber cables are commercially available; they are not available from Cisco.

Note We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the

“Fiber Optic Cleaning Information” section on page 6-23 for information.

1. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance (tens of meters) can cause transceiver saturation resulting in an elevated bit error rate (BER). In addition, when using the LX/LH SFP module with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the SFP module and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 ft (300 m).

Console and Auxiliary Port Connection Equipment

The NPE-G2 has a DCE-mode console port for connecting a console terminal, and a DTE-mode auxiliary port for connecting a modem or other DCE device (such as a CSU/DSU or other router) to your router. However, with an I/O controller also installed in the router, the default console and auxiliary ports are on the I/O controller, and you cannot access the console and auxiliary ports on the NPE-G2.

Note Both the console and the auxiliary ports are asynchronous serial ports; any devices connected to these

ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

The NPE-G2 uses RJ-45 media for console port and auxiliary port connections.

Note Cisco IOS Release 12.2 changed the behavior of the ROM monitor (ROMmon) during the bootup

sequence. See the “Boot Changes in Cisco IOS Release 12.2” section on page 10-2 for more information.

Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information

Upgrading to the NPE-G1 or NPE-G2 is a different procedure than previous processor upgrades because of the following considerations:

• The NPE-G1 and NPE-G2 contain an I/O controller, which includes the bootflash and NVRAM

memory. After you install the NPE-G1 or NPE-G2 in a chassis, you can no longer access the bootflash and NVRAM on the I/O controller. You therefore must make the existing Cisco

IOS software image and configuration files available to the NPE-G1 or NPE-G2, either by putting these files on a CompactFlash Disk or on a TFTP server.

• The NPE-G1 and NPE-G2 include three Gigabit Ethernet interfaces. If you want to use these

interfaces to replace the Ethernet or Fast Ethernet interfaces on the existing I/O controller, you must configure the new interfaces before they can be used to access the network. If you are also removing the existing I/O controller, you must remove the configuration for its Ethernet or Fast Ethernet interfaces.

Note The NPE-G2 provides a Fast Ethernet Management port, as well as three RJ-45 Gigabit

Ethernet ports.

• The NPE-G1 and NPE-G2 use Type 1 CompactFlash Disk memory instead of the Type 2 Flash Disk

memory used in existing I/O controllers. You must transfer any information currently saved on Flash Disks to CompactFlash Disks so that it can be used after the upgrade to the NPE-G1 or NPE-G2.

Note If you are upgrading to an NPE-G2 from an NPE-G1, you do not need to perform the following

procedure.

7-2

To ensure a smooth upgrade, perform the following procedure only if you are upgrading to an NPE-G1 or NPE-G2 from an NPE-400 or earlier network processing engine.

Network Processing Engine and Network Services Engine Installation and Configuration

OL-4448-12

Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information

Before you install an NPE-G1 or NPE-G2 in an existing router and remove the existing processor and I/O controller, do the following:

Step 1 Copy the configuration file from the existing router to a TFTP server, Flash Disk, or PC Card. See the

“Copying the Configuration File” section on page 7-4 for details.

Step 2 Modify the configuration file to accommodate the new Gigabit Ethernet interfaces on the NPE-G1 or

NPE-G2. If you are also planning to remove the I/O controller, also remove the configuration lines for the Ethernet or Fast Ethernet interfaces on the I/O controller. See the

Ethernet Interfaces” section on page 7-56 for guidelines.

Step 3 Copy the modified configuration file to a CompactFlash Disk that can be used on the NPE-G1 or

NPE-G2. If you are not planning on removing the existing I/O controller, you can do this by copying the configuration to a Flash Disk, as described in you can keep the Flash Disk in the I/O controller and copy it to a CompactFlash Disk in the NPE-G1 or NPE-G2 after you have finished installing the NPE-G1 or NPE-G2.

If you are planning on removing the existing I/O controller, you can copy the configuration file to a CompactFlash Disk in the following ways:

• Copy the configuration file to a TFTP server and then copy it to a CompactFlash Disk on an existing

NPE-G1 or NPE-G2.

Preparing for an Upgrade

“Configuring the Native Gigabit

Step 1, before you install the NPE-G1 or NPE-G2. Then

• Copy the configuration file to a Type 2 Flash Disk using the existing I/O controller, as described in

the

“Copying the Configuration File to a Flash Disk or PC Card” section on page 7-4. Then use a

multi-function reader that accommodates both Type 1 CompactFlash Disk and Type 2 Flash Disk memory cards to transfer the configuration file to the CompactFlash Disk.

• Use a Type 1-to-Type 2 adapter to convert the CompactFlash Disk to the Flash Disk form factor.

Then insert the CompactFlash Disk and adapter into the existing I/O controller and copy the configuration file to it, as described in

Note The CompactFlash Disk must be formatted before you can write any files to it. The

Step 1.

CompactFlash Disk shipped with the NPE-G1 or NPE-G2 is already formatted, but a spare

CompactFlash Disk must be formatted using the format command. Do not format the

CompactFlash Disk in a PC or other workstation because the router cannot use CompactFlash

Disks that are formatted by other computers. After the CompactFlash Disk is properly formatted,

however, you can write to it using any PC or workstation that recognizes Type 2 CompactFlash

Disk memory.

Step 4 (Optional) Copy the proper Cisco IOS software image (see Ta ble 8-4 on page 8-4) to the CompactFlash

Disk, using the same technique you used to copy the configuration file in Step 3. You do not need to perform this step if you plan to boot the router from a TFTP server, but you must add the proper boot configuration command to the configuration file when you modify it in

Step 2.

Network Processing Engine and Network Services Engine Installation and Configuration

7-3

Copying the Configuration File

Caution Before powering down the router to install the NPE-G1 or NPE-G2, you must save the current

configuration to a Flash Disk, PC Card, Trivial you install the NPE-G1 or NPE-G2, or the configuration will be lost and you will have to manually re-enter your configuration.

Cisco IOS looks to the NPE-G1 or NPE-G2 NVRAM for the startup running configuration, because the NPE-G1 or NPE-G2, by default, stores the running configuration, whether or not an I/O controller is installed with the NPE-G1 or NPE-G2.

The following sections provide instructions for copying the file to a Flash Disk, PC Card, or TFTP server, and for copying it manually using a terminal program on a PC:

• Copying the Configuration File to a Flash Disk or PC Card, page 7-4

• Copying the Configuration File to a TFTP Server, page 7-5

Copying the Configuration File to a Flash Disk or PC Card

Use the following instructions for copying the router configuration file to a Flash Disk or PC Card.

Caution If the NPE-G1 or NPE-G2 will be installed in a router with either a C7200-I/O-GE/E or

C7200-I/O-2FE/E I/O controller, copy your running configuration to a Flash Disk, not a PC Card. PC Cards are not supported on these I/O controllers when an NPE-G1 or NPE-G2 is present. If you copy the running configuration to a PC Card with these I/O controllers present, you will not be able to retrieve the running configuration after the NPE-G1 or NPE-G2 is installed.

Step 1 Insert the Flash Disk or PC Card into I/O controller PC Card slot 0. If slot 0 is full, use slot 1. If you

need to format the Flash Disk, go to Step 2. If the Flash Disk is already formatted, go to

Step 2 Use the format disk0: command to format a Flash Disk in slot 0. Use the format disk1: command to

format a Flash Disk in slot 1. If you are using a PC card, use slot0 or slot1 as part of the command.

System# format disk0: Format operation may take a while. Contineu: [confirm] Format operation will destroy all data in ‘disk0:’. Continue? [confirm] Format :Drive communication and 1st Sector Write OK... Writing Monlib sectors

Step 3 Make sure you are at the privileged level of the EXEC command interpreter (check the system prompt

for a pound sign [#]). If the system prompt does not have a pound sign (#), enter enable, and then your password.

Step 4 Enter the show running-config command to display the router’s running configuration. Ensure that the

configuration information is complete and correct. If it is not, use the configure command to add or modify the existing configuration. Then enter the copy Disk 0 or 1, use disk0 or disk1 as part of the command. If you are using a PC Card, use slot0 or slot1 as part of the command.

Step 5 To copy the running configuration file to the Flash Disk or PC Card, enter the copy running-config

disk0: filename or copy running-config slot0: filename command:

System# copy running-config disk0: filename

You have finished copying the running configuration file to the Flash Disk or PC Card.

Copying the Configuration File to a TFTP Server

Before copying the router configuration file to a TFTP file server, check the following items:

• A console terminal is connected to the console port on the I/O controller or a Telnet session is

established to the router.

• The router is connected to a network supporting a file server (remote host).

• The remote host supports the TFTP application.

• You have the name or address of the remote host.

Complete the following steps to copy the router’s configuration file to a remote host:

Step 1 Make sure you are at the privileged level of the EXEC command interpreter (check the system prompt

for a pound sign [#]). If the system prompt does not have a pound sign (#), enter enable, and then your password.

Step 2 Use the ping command to check the connection between the router and the remote host. Step 3 Enter the show running-config command to display the router’s running configuration. Ensure that the

configuration information is complete and correct. If it is not, use the configure command to add or modify the existing configuration. Then enter the copy save the retrieved configuration in NVRAM. NVRAM uses lithium batteries to maintain its contents when disconnected from power.

Copying the Configuration File

Step 4 Enter the copy startup-config tftp command. The EXEC command interpreter prompts you for the

name or IP address of the remote host that is to receive the configuration file. (The prompt might include the name or address of a default file server.)

Router# copy startup-config tftp Remote host []?

Step 5 Enter the name or IP address of the remote host. In the following example, the name of the remote host

is servername:

Router# copy startup-config tftp Remote host []? servername Translating "servername"...domain server (10.1.1.1) [OK]

Step 6 The EXEC command interpreter prompts you for the name of the file that will contain the configuration.

By default, the system appends -confg to the router’s name to create the new filename. Press Return to accept the default filename, or enter a different name for the file before pressing Return. In the following example, the default is accepted:

Name of configuration file to write [Router-confg]? Write file Router-confg on host 10.1.1.1? [confirm]

Writing Router-confg.....

Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information

Step 7 Before the router executes the copy process, it displays the instructions you entered for confirmation. If

the instructions are not correct, enter n (no), and then press Return to stop the process. To accept the instructions, press Return, or y and then press Return; the system begins the copy process. In the following example, the default is accepted:

Write file Router-confg on host 10.1.1.1? [confirm] Writing Router-confg: !!!! [ok]

While the router copies the configuration to the remote host, it displays a series of exclamation points (!

! !) or periods (. . .). The !!!! and [ok] indicate that the operation is successful. A display of . . . [timed

out] or [failed] indicates a failure, which would probably be because of a network fault or the lack of a writable, readable file on the remote file server.

Step 8 Check the result of the copy process.

• If the display indicates that the process was successful (with the series of exclamation points [! ! !]

and [ok]), the copy process is complete. The configuration file is safely stored in the temporary file on the remote file

• If the display indicates that the process failed (with the series of periods [. . .] as shown in the

server.

following example), your configuration was not saved:

Writing Router-confg .....

Step 9 If your configuration was not saved, repeat the preceding steps, or select a different remote file server

and repeat the preceding steps. If you are unable to copy the configuration to a remote host successfully, contact your network administrator or see the

“Obtaining Documentation and Submitting

a Service Request” section on page iv for instructions on contacting technical assistance.

Copying the Configuration File Using a PC

Complete the following steps to copy the router’s configuration file to a text file on a PC connected to the router’s console port.

Step 1 Connect a serial port on the PC to the router’s console port. Start a terminal program on the PC and

configure it for the same baud rate, parity, and stop-bits that the console port is using.

Step 2 Turn on the terminal program’s capture buffer so that it will save all output to a text file. Step 3 Enter the show startup-config command in privileged EXEC mode to display the router’s startup

configuration.

Note Refer to the appropriate software documentation listed in the “Related Documentation” section

on page iii for descriptions of the configuration options available for the system and individual

interfaces, and for specific configuration instructions.

Step 4 When the router has completed displaying the configuration, turn off the terminal program’s capture

buffer and save the configuration file to the disk on the PC.

Step 5 (Optional) Use a text editor on the PC to modify the configuration, as needed.

Removing the Network Processing Engine

This completes the procedure for copying the configuration file to a PC. Proceed to “Removing the

Network Processing Engine” section on page 7-7.

Removing the Network Processing Engine

Before you begin any removal or installation procedure, read Chapter 8, “Preparation for Installation.” To install the NPE-G1 or NPE-G2, follow the instructions in this chapter for removal of an existing network processing engine or network services engine and installation of the NPE-G1 or NPE-G2.

Note If you are removing the I/O controller, and do not plan to replace it, you must install an I/O controller

blank panel (Cisco Product Number IO-CONTROLR-BLANK=) in the I/O controller slot. See the

Ensuring Easy Access to the Router

If your Cisco 7200 VXR router or Cisco uBR7200 series router is installed in a standard 19-inch, 4-post or telco-type rack, cables from other equipment in the rack might obstruct access to the rear of the router. Also, rack power strips or other permanent fixtures may obstruct access to the router. Review the following guidelines to ensure easy access to the rear of the router when it is installed in a rack. This is particularly important because the NPE-G1 and NPE-G2 have interfaces that require cabling on the rear of the router.

If the router is not installed in a rack, or if you already have clear access to the rear of the router, proceed to the

“Powering Down the Router and Disconnecting Input Power” section on page 7-8.

Use the following guidelines to ensure easy access to the rear of the router when it is installed in a rack:

• Ensure that you have at least 3 to 4 feet (0.91 to 1.22 meters) of working space at the rear of the

router.

• If cables from other equipment in the rack fall in front of the rear end of the router, carefully gather

the cables (using care not to strain or stress them) and use cable ties to anchor them away from the rear of the router.

• If access to the rear of the router is partially blocked by a power strip or some other permanent rack

fixture, detach the router from the rack and carefully slide it forward until there is enough clearance to remove the power supply, the network processing engine, and the subchassis from the router.

Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information

Caution Make sure that at least one other person is available to support the front of the router as you slide it out

from the rack and, if necessary, to continue to support it while you remove and insert the power supply, network processing engine, or subchassis.

Powering Down the Router and Disconnecting Input Power

Complete the steps in the following sections to power down the router and disconnect input power.
