Router Information

For hardware installation and maintenance information on Cisco 12000 Series Routers, refer to the installation and configuration guide for your router. This includes information on card slot locations and other general requirements.

Supported Platforms

The PRP operates on all Cisco 12000 Series Routers and can be installed in any available slot in any chassis. Cisco recommends that you install the PRP in the section of the chassis that receives the least amount of airflow (if any). The PRP runs cooler than other system cards and, therefore, does not require as much airflow.

Performance Route Processor Installation and Configuration Guide

OL-11656-01

PRP Redundancy

When two PRPs are installed in a Cisco 12000 Series Router, one PRP is the active PRP and the other is a backup, or standby, PRP. If the active PRP fails or is removed from the system, the standby PRP detects the failure and initiates a switchover. During a switchover, the standby PRP assumes control of the router, connects with the network interfaces, and activates the local network management interface and system console.

Note If your system includes redundant PRPs, both PRPs should be of the same type

(PRP-1 or PRP-2) and have the same memory size. Redundancy is not supported when using a Gigabit Route Processor (GRP) and a PRP in the same chassis. Cisco strongly recommends that you avoid configuring your router using mixed route processor cards. Refer to the Route Processor Redundancy Plus for the Cisco 12000 Series Internet Router publication for more information on redundancy.

Cisco IOS Software Requirements

Important Information

OL-11656-01

For software configuration information, refer to the Cisco IOS software configuration and command reference publications for the installed Cisco IOS Release. Also refer to the Cisco IOS software release notes for additional information.

The PRP is compatible with Cisco IOS Release 12.0(22)S or later.

The show version and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running. For complete descriptions of show commands, refer to the

Cisco IOS Configuration Fundamentals Configuration Guide and the Cisco IOS Configuration Fundamentals Command Reference.

Performance Route Processor Installation and Configuration Guide

Important Information

Note Output from the show version command on a PRP-2 card running on software

releases prior to 12.0(30)S may display some incorrect information. This is only a display issue and it occurs because the software does not recognize some of the hardware on the card. This does not affect the functionality of the PRP-2. For example, the following is incorrect output from the show version command on release 12.0(22)S:

cisco 12406/PRP (MPC7450) processor (revision 0x00) with 1048576K

bytes of memory. unknown CPU at 598Mhz, Rev 1.1, 256KB L2, 2048KB L3

Cache

The output from a later software release would be as follows:

cisco 12406/PRP (MPC7457) processor (revision 0x00) with 1048576K

bytes of memory. MPC7457 CPU at 1263Mhz, Rev 1.1, 512KB L2, 2048KB L3

Cache

Hardware Revision Requirements

To ensure compatibility with the software, the PRP should have a specific hardware revision level or greater. The hardware revision number is printed on a label affixed to the component side of the card. The hardware revision number can also be displayed using the show diags slot-number command.

The minimum hardware revision number for the PRP (Product Number PRP-1=) is 73-5936-05, Rev. A0. The minimum hardware revision number for the PRP-2 (Product Number PRP-2=) is 73-8812-04 Rev. A0.

Note Output from the show diags command on a PRP-2 card running on software

releases prior to 12.0(30)S may incorrectly indicate “PRP-1+” or “FRU number not known” as the installed FRU.

PRP-2 board.

• CF—1-GB compact flash disk can be optionally installed on the PRP-2

board.

Cisco IOS Software Storage

The Cisco IOS software images that run the Cisco 12000 Series Router system are stored in Flash memory. Two types of Flash memory ship with the PRP-1:

• Onboard Flash memory—Ships as a single in-line memory module (SIMM).

This Flash memory contains the Cisco IOS boot image (bootflash) and is not field replaceable.

• Flash disk—The PRP ships with an ATA Flash disk that can be installed in

either Flash disk slot. The Flash disk contains the Cisco IOS software image. Linear Flash memory cards are also supported in the PRP-1.

Performance Route Processor Installation and Configuration Guide

OL-11656-01

The PRP-2 provides the following additional Flash memory:

• Compact Flash (CF) disk—Optional 1 GB CF can be used for large IOS

images.

Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS software images remotely, or from software images that reside in PRP Flash memory.

Cisco 12000 Series Routers support downloadable system software for most Cisco IOS software upgrades. This enables you to remotely download, store, and boot from a new Cisco IOS software image. The Cisco IOS software runs from within the SDRAM of the PRP.

For specific Cisco IOS software requirements for the PRP, see the “Cisco IOS

Software Requirements” section on page 3.

Product Overview

Flash Memory

PRP LEDs

Flash memory allows you to remotely load and store multiple Cisco IOS software and microcode images. You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You then can boot the routers either manually or automatically from any of the stored images.

Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory. The onboard Flash memory (called bootflash) contains the Cisco IOS boot image, and the Flash disk contains the Cisco IOS software image.

The following LEDs are used on the PRP:

• Status LEDs

• Display LEDs

Status LEDs

The PRP-1 has the following Status LED indicators:

• Two Flash disk activity LEDs, one for each Flash disk slot (labeled SLOT-0

and SLOT-1)—Indicate when the Flash disk slot is accessed.

• Four Ethernet port LEDs used in conjunction with each of the RJ-45 Ethernet

connectors:

–

LINK—link activity

–

EN—port enabled

–

TX—data transmission

–

RX data reception

• Two Ethernet connection LEDs, one for each Ethernet port (labeled

PRIMARY)—Identify which of the two Ethernet connections is selected.

Product Overview

The PRP-2 has the following LED indicators:

• Two Flash disk activity LEDs, one for each Flash disk slot (labeled SLOT-0

and SLOT-1)—Indicate when the Flash disk slot is accessed.

• Two Ethernet port LEDs used in conjunction with each of the three RJ-45

Ethernet connectors:

–

LINK—indicates link activity

–

DATA—indicates data transmission or reception

• Two BITS port LEDs used in conjunction with each of the two BITS ports:

–

SIG—indicates carrier signal available

–

ACT—indicates the interface is active

The alphanumeric display LEDs are organized as two rows of four characters each and are located at one end of the card. These LEDs provide system status and error messages that are displayed during and after the boot process. The boot process and the content displayed are controlled by the MBus module software of the PRP.

At the end of the boot process, the LEDs are controlled by the Cisco IOS software (via the MBus), and the content displayed is designated by the Cisco IOS software.

A complete, descriptive list of all system and error messages is located in the Cisco IOS System Error Messages publications.

OL-11656-01

The display LEDs indicate the following:

• Status of the PRP

• System error messages

• User-defined status/error messages

Performance Route Processor Installation and Configuration Guide

Product Overview

Soft Reset Switch

A soft reset switch provides a reset to the processor software on the PRP. You access the soft reset switch through a small opening in the PRP faceplate. To depress the switch, insert a paper clip or a similar object into the opening.

Caution The soft reset switch is not a mechanism for resetting the PRP and reloading the

IOS image. It is intended for software development use. To prevent system problems or loss of data, use the soft reset switch only on the advice of Cisco service personnel.

Flash Disk Slots

The PRP includes two Flash disk slots on the front panel of the card. Either slot on the PRP-1 can support an ATA Flash disk or a linear Flash memory card. The Flash disk slots on the PRP-2 can only support ATA Flash disks.

Note The PRP only supports +5 VDC Flash disk devices. It does not support +3.3 VDC

Flash disk devices.

All combinations of different Flash devices are supported by the PRP-1. You can use ATA Flash disks, linear Flash memory cards, or a combination of the two.

Each Flash disk slot has an ejector button for ejecting a card from the slot. See the

“Using Flash Disks in the PRP” section on page 61 for more information.

Note Linear Flash memory cards may not have the capacity to meet the requirements

of your configuration. However, they can be used for emergency file recovery applications.

Performance Route Processor Installation and Configuration Guide

OL-11656-01

Asynchronous Serial Ports

The PRP has two asynchronous serial ports, the console and auxiliary ports. These allow you to connect external serial devices to monitor and manage the system. Both ports use RJ-45 receptacles.

The console port provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal. The auxiliary port provides a data terminal equipment (DTE) interface and supports flow control. It is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

Ethernet Ports

The PRP includes two 10/100 Mbps Ethernet ports, each using an 8-pin RJ-45 receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections.

The PRP-2 includes a 10/100/1000 Mbps Ethernet port, which uses the above connections and also a 802.3 Gigabit Ethernet connection.

Product Overview

Note The transmission speed of the Ethernet ports is auto-sensing by default and is user

configurable.

Hard Disk Drive

The PRP-2 optionally includes a 40-GB hard disk drive (HDD) that is installed on the PRP-2 board.

Note Non-Cisco hard disk drives are not supported.

Preparing for Installation

Compact Flash Disk

The PRP-2 optionally includes a 1-GB compact flash disk that is installed on the PRP-2 board.

Note Non-Cisco compact flash disks are not supported.

Preparing for Installation

Installation preparation is presented in the following sections:

• Safety Guidelines, page 18

• Preventing Electrostatic Discharge, page 19

• Required Tools and Equipment, page 20

• Working with Electrical Equipment, page 20

Safety Guidelines

Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.

The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.

Note Review the safety warnings listed in the Regulatory Compliance and Safety

Information for Cisco 12000 Series Internet Router publication (Document

Number 78-4347-xx) that accompanied your router before installing, configuring, or maintaining a line card.

• Keep the work area clear and dust free during and after installation. Do not

the router while working with line cards.

OL-11656-01

• Cisco equipment operates safely when it is used in accordance with its

specifications and product usage instructions.

• If you plan to replace a PRP, back up your current configuration file to a

remote server or to Flash memory before you remove the PRP. This prevents you from having to reenter all your current configuration information manually. To back up the file, copy your configuration file to a Flash disk or access a remote server.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI) shielding is an integral component of the line card. Cisco recommends using an ESD-preventive strap whenever you are handling network equipment or one of its components.

The following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist or ankle strap and ensure that it makes

good skin contact. Connect the equipment end of the connection cord to an ESD connection socket on the router or to bare metal on the chassis.

• Handle PRPs by the captive installation screws, the provided handle, ejector

levers, or the line card metal carrier only; avoid touching the board or connector pins.

Preparing for Installation

OL-11656-01

Warning

• Place removed PRPs board-side-up on an antistatic surface or in a static

shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag.

• Avoid contact between the PRPs and clothing. The wrist strap only protects

the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.

For safety, periodically check the resistance value of the ESD strap. The measurement should be between 1 and 10 megohms.

Performance Route Processor Installation and Configuration Guide

Removing and Installing a PRP

Required Tools and Equipment

You need the following tools and parts to remove and install a PRP:

• Flat-blade or Phillips screwdriver

• ESD-preventive wrist strap and instructions

• Antistatic mat, foam pad, or bag for the removed PRP. Place the removed PRP

into an antistatic bag if you plan to return it to the factory, or on an antistatic mat or foam if you are replacing components and will reinstall the PRP.

Working with Electrical Equipment

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedure requiring access to the chassis interior,

locate the emergency power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not work alone when potentially hazardous conditions exist; never assume

that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes

the equipment unsafe.

• Carefully examine your work area for possible hazards such as moist floors,

ungrounded power extension cables, and missing safety grounds.

Removing and Installing a PRP

The following sections describe the procedures for removing and installing a PRP as well as removing and installing other field-replaceable hardware on the PRP-2 board. Before beginning the procedures, verify that your system meets the minimum requirements as described in the “Preparing for Installation” section on

page 18.

• Removing a PRP, page 21

• Installing a PRP, page 24

Performance Route Processor Installation and Configuration Guide

OL-11656-01

Removing and Installing a PRP

Note The procedures in the following sections use illustrations of a Cisco 12404

Internet Router to support the descriptions of installing and removing a route processor card. The card cages of Cisco 12000 Series Routers differ in many ways. However, the process of installing and removing a route processor card are basically the same across the entire chassis line. Therefore, separate procedures and illustrations for each chassis are not included in this publication.

Caution Cisco recommends that you do not remove a PRP while the system is operating.

Doing so will cause the system to stop forwarding packets and might cause the system to cease network operation. If you are upgrading your router from a GRP to a PRP, you must first power down the router and then switch out the RP cards. Cisco strongly recommends that you avoid configuring your router using mixed RP cards. If RP redundancy is desired, you must install two PRPs.

Note You must remove the PRP-2 before you can install or remove the compact flash

disk or the hard disk drive. See the “Additional Configuration and Maintenance

Tasks” section on page 54 for more information.

Removing a PRP

When you remove a PRP from a slot, be sure to use the ejector levers, which help to ensure that the PRP is fully dislodged from the backplane connector. A PRP that is only partially removed from the backplane can halt the system. (See

Figure 6.)

Caution Before you replace the PRP, back up the running configuration to a TFTP server

or a Flash disk so that you can retrieve it later. If the configuration is not saved, it will be lost and you will have to reenter the entire configuration manually. This procedure is not necessary if you are temporarily removing a PRP; lithium batteries will retain the configuration in memory until you replace the PRP in the system.

To remove a PRP, follow these steps:

Step 1 If you are replacing the PRP in a system with only one PRP, copy the currently

running configuration file to a TFTP server or to a Flash disk so that you can retrieve it later.

Step 2 Turn off system power.

Step 3 Attach an ESD-preventive wrist strap and follow its instructions for use.

OL-11656-01

Step 4 If you are replacing a PRP, disconnect any devices that are attached to the

Ethernet, console, or auxiliary ports. If you are removing a PRP for maintenance and will reinstall the same one, you can leave the devices attached, provided that doing so will not strain the cables.

Step 5 Using a 3/16-inch flat-blade screwdriver, loosen the two captive screws on the

ends of the PRP.

pull them both away from the PRP faceplate (in the direction shown in Figure 6a) to release the PRP from the upper card cage slot and to dislodge the PRP edge connector from the backplane.

Step 7 Grasp the PRP faceplate handle with one hand and pull the PRP straight out of the

slot, keeping your other hand under the PRP to guide it. Keep the PRP edge connector parallel to the backplane.

Caution Avoid touching the PRP printed circuit board, components, or any edge connector

pins.

Step 8 Place the removed PRP on an antistatic mat or foam. If you plan to return the PRP

to the factory, immediately place it in an antistatic bag to prevent ESD damage.

Installing a PRP

When you install a PRP, be sure to use the ejector levers, which help to ensure that the PRP is fully inserted in the backplane connector. (See Figure 6.) When you push the ejector levers simultaneously inward (toward the center of the PRP), the ejector levers push the PRP into the slot and ensure that the PRP backplane connector is fully seated in the backplane.

Caution A PRP that is only partially connected to the backplane can halt the system.

To install a PRP, follow these steps:

Step 1 Turn off system power.

Step 2 Attach an ESD-preventive wrist strap and follow its instructions for use.

Step 3 Grasp the PRP faceplate handle with one hand and place your other hand under

the carrier to support and guide it into an upper card cage slot.

Removing and Installing a PRP

Caution Avoid touching the PRP printed circuit board, components, or any edge connector

pins.

Step 4 Place the bus-connector edge of the PRP in the appropriate slot and align the

notches along the edge of the carrier with the grooves at the top and bottom of the slot.

Step 5 While keeping the PRP edge connector parallel to the backplane, carefully slide

the carrier into the slot until the PRP faceplate makes contact with the ejector levers, then stop.

Step 6 Using the thumb and forefinger of each hand to pinch each ejector lever, push both

ejectors simultaneously toward the center of the PRP faceplate until they are perpendicular to the PRP faceplate. (See Figure 6b.)

Step 7 Using a 3/16-inch flat-blade screwdriver, tighten the captive screws on the ends

of the PRP. The captive screws prevent the PRP from becoming partially dislodged from the backplane and ensure proper EMI shielding. (These captive screws must be tightened to meet EMI specifications.)

Step 8 If you disconnected cables to remove the PRP, or if you are installing a new PRP,

reconnect the cables to the appropriate ports. (See the “Checking the Installation”

section on page 26.)

Step 9 Ensure that the console terminal is turned on.

Step 10 Turn on system power.

Step 11 Attach the network end of your RJ-45 cable to your transceiver, switch, hub,

repeater, DTE, or other external equipment. Be sure to use the appropriate strain relief on cable connections.

Checking the Installation

This section assists you in confirming that the PRP is installed successfully and includes the following sections:

• PRP Boot Process, page 26

• Starting the System and Observing Initial Conditions, page 27

• Verifying Interface Status, page 31

PRP Boot Process

The following sequence describes a typical PRP boot process:

1. System power is turned on.

2. MBus module receives +5 VDC and starts executing MBus software.

3. PRP determines the system configuration by sending a message over the

MBus requesting all installed devices to identify themselves. The return response provides slot number, and card and component type. The PRP, line cards, and clock scheduler cards (CSCs) are then powered up.

4. PRP power-on-reset logic delay, which allows power and both local and CSC

clocks to stabilize.

5. After the power-on reset is released, the PRP begins to execute the ROM

monitor software.

6. If the ROM monitor is configured to autoboot, it loads and boots the Cisco

IOS software.

If the ROM monitor is not configured to autoboot, you must enter the appropriate b command at the ROM monitor prompt ( Cisco IOS software.

7. When the Cisco IOS software boots, it polls all other cards in the system and

powers them up, loading their Cisco IOS software as needed.

Starting the System and Observing Initial Conditions

This section describes the initial system startup processes and procedures.

To start your system, follow these steps:

Step 1 Turn on each installed power supply by turning its system power switch to the on

(|) position.

For AC-input power supplies, the green AC OK LED should go on. For DC-input power supplies, the green input OK LED should go on. For both types of power supplies, the output fail LED should be off.

Step 2 Listen for the system blower modules or fan trays in the router; you should

immediately hear them operating. In a noisy environment, place your hand in front of the exhaust vents to verify that the blower modules are operating.

Step 3 During the PRP boot process, observe the PRP alphanumeric display LEDs,

which are located at one end of the PRP, near the ejector lever. (See Figure 7.)

The 4-digit displays show system messages and displays a sequence similar to that shown in Tab le 2.
