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.

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

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.


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.

Product Overview

The following sections provide information about the Performance Route Processor (PRP), its components, functions, and features, and its use as the main system processor for Cisco 12000 Series Routers. Figure 1 shows the front panel view of the PRP-1.

Figure 1 PRP-1, Front Panel View

The PRP-1 is available as Product Number PRP-1 or PRP-1=, which includes one PRP with 512 MB of synchronous dynamic random-access memory (SDRAM) and one 64-MB advanced technology attachment (ATA) Flash disk. A redundant PRP (Product Number PRP-1/R) is also available.

Figure 2 shows the front panel view of the PRP-2.

Figure 2 PRP-2, Front Panel View

The PRP-2 is available as Product Number PRP-2 or PRP-2=, which includes one PRP with 1 G of synchronous dynamic random-access memory (SDRAM) and one 64-MB advanced technology attachment (ATA) Flash disk. A redundant PRP (Product Number PRP-2/R) is also available.

PRP Functions

The PRP-1 for the Cisco 12000 Series Router includes the following primary functions:

Loading Cisco IOS software on all installed line cards at power up

Providing a console (terminal) port for router configuration

Providing an auxiliary port for other external equipment (such as modems)

Providing two IEEE 802.3, 10/100-megabits-per-second (Mbps) Ethernet ports for Telnet functionality

Running routing protocols

Building and distributing routing tables to line cards

Providing general system maintenance functions

Communicating with line cards either through the switch fabric or through the maintenance bus (MBus). The MBus connection allows the PRP to download a system bootstrap image, collect or load diagnostic information, and perform general, internal system maintenance operations. The switch fabric connection is the main data path for routing table distribution as well as for packets that are sent between line cards and the PRP.

In addition to the functionality listed for the PRP-1, the PRP-2 provides the following additional functions:

One IEEE 802.3 10/100/1000-megabits-per-second (Mbps) Ethernet port

Two building integrated timing system (BITS) ports for connecting to an external clock source

PRP Components

The PRP-1 contains the following components:

PowerPC processor—Motorola PowerPC 7450 central processing unit (CPU). The CPU runs at an external bus clock speed of 133 MHz and an internal clock speed of 667 MHz.

SDRAM—Up to 2 gigabytes (GB) of Cisco-approved synchronous dynamic random-access memory (SDRAM) on two dual in-line memory modules (DIMMs). 512 MB of SDRAM is the default shipping configuration. SDRAM is field replaceable only when using Cisco-approved DIMMs.

SRAM—2 megabytes (MB) of static random-access memory (SRAM) for secondary CPU cache memory functions. SRAM is not user configurable or field replaceable.

NVRAM—2 MB of nonvolatile RAM (NVRAM). NVRAM is not user configurable or field replaceable.

Memory—Additional memory components include onboard Flash memory and up to two Flash disks.

Sensors—Air-temperature sensors for environmental monitoring.

The PRP-2 contains the following additional components:

SDRAM—Up to 4 GB of Cisco-approved synchronous dynamic random-access memory (SDRAM) on two dual in-line memory modules (DIMMs). 1 GB of SDRAM is the default shipping configuration. SDRAM is field replaceable only when using Cisco-approved DIMMs.


Note Software releases prior to 12.0(30)S do not recognize more than 2 GB of SDRAM and will only use the first 2 GB of the installed memory. This does not affect the functioning of the PRP-2, but commands such as show version will indicate that only 2 GB of SDRAM are installed.


Hard disk drive—40-GB hard disk drive can be optionally installed on the 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.

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.

7 Optional PRP-2 hardware. Non-Cisco compact disks are not supported.

8 Optional PRP-2 hardware. Non-Cisco hard disk drives are not supported.



Note If a single DIMM module is installed, it must be placed in bank 1 (U15).


SDRAM

SDRAM stores routing tables, protocols, and network accounting applications, and runs the Cisco IOS software. The default PRP-1 configuration includes 512 MB of error checking and correction (ECC) SDRAM. DIMM upgrades of 512 MB and 1 GB are available for the PRP-1. You cannot mix memory sizes. If two DIMMS are installed, they must be the same memory size.

The default PRP-2 configuration includes 1 GB of ECC SDRAM. DIMM upgrades of 1 GB and 2 GB are available for the PRP-2. You can mix memory sizes as long as the larger DIMM is placed in bank 1 (U15).


Caution Only Cisco-approved memory is supported. Do not attempt to install other devices or non-Cisco approved DIMMs in the DIMM sockets. (See Table 15.)

SRAM

SRAM provides 2 MB of parity-protected, secondary CPU cache memory. Its principal function is to be a staging area for routing table updates and for information sent to and from line cards. SRAM is not user configurable or field replaceable.

NVRAM

NVRAM provides 2 MB of memory for system configuration files, software configuration register settings, and environmental monitoring logs. This information is backed up with built-in lithium batteries that retain the contents for a minimum of 5 years. NVRAM is not user configurable or field replaceable.

Flash Memory

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.

PRP LEDs

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.

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

Display LEDs

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.

The display LEDs indicate the following:

Status of the PRP

System error messages

User-defined status/error messages

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 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.


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.


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.


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:

Required Tools and Equipment

Working with Electrical Equipment

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 allow dirt or debris to enter into any laser-based components.

Do not wear loose clothing, jewelry, or other items that could get caught in the router while working with line cards.

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.

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.


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


 

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.

Removing a PRP

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 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.

Figure 5 illustrates the PRP installed in a chassis.

Ejector Levers


Figure 6 shows the ejector levers in detail.

Figure 6 Ejector Lever Detail (Cisco 12404 shown)

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.

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.

Step 6 Place your thumbs on the ends of each of the ejector levers and simultaneously 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.


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.)

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

Starting the System and Observing Initial Conditions

Verifying Interface Status

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.

or

If the ROM monitor is not configured to autoboot, you must enter the appropriate b command at the ROM monitor prompt (Rommon>) to boot the 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 Table 2.

Cisco IOS is enabled and this PRP is the active PRP.

STBY
RP

Cisco IOS is enabled and this PRP is in standby mode.

1 The version of microcode running on your PRP might be different.


Step 4 During the line card boot process, which occurs immediately after the PRP boots, observe the alphanumeric display LEDs on each line card.

The system attempts to boot identical line cards in parallel. Furthermore, the system boots line cards as soon as they are powered on and become available for a system boot. The physical location of the alphanumeric display LEDs on the line cards is the same as on the PRP, which is shown in Figure 7.

See the appropriate line card installation and configuration note for complete details on line card display LED sequences.

You must meet the following criteria to successfully boot the PRP:

Flash disk is installed in Flash disk slot 0

Flash disk contains a valid Cisco IOS software image

Software configuration register is set to 0x2102

The system automatically boots this Cisco IOS software image. The system then enters the setup facility, where you are prompted to perform a basic configuration of the system.

Otherwise, the system enters the ROM monitor and the appropriate prompt appears (Rommon>).

Step 5 If the ROM monitor prompt (Rommon>) appears, you must boot the Cisco IOS software image you want to use by entering the appropriate b command at the ROM monitor prompt:

b—Boots the default system software from onboard Flash memory
(if it is present in onboard Flash memory)

b filename [host]Boots the file filename from the server host using TFTP

b flash—Boots the first file in the Flash memory card in Flash card slot 0


Caution To prevent system problems, use the b flash command option carefully; otherwise, you might instruct the system to boot a non-Cisco IOS software image from Flash memory. This command is not used with Flash disks.

b slot0: filename—Boots the file filename from the Flash memory card in Flash card slot 0

b slot1: filename—Boots the file filename from the Flash memory card in Flash card slot 1

b flash disk0: filename—Boots the file filename from the Flash disk in Flash card slot 0

b flash disk1: filename—Boots the file filename from the Flash disk in Flash card slot 1


Caution The b flash disk0: and b flash disk1: commands are only used from the ROM monitor (Rommon>) prompt if the system fails to load normally. Do not use these commands from the router (Router>) prompt.

While the system boots, the console screen displays a script and system banner similar to the following:

Cisco Internetwork Operating System Software
IOS (tm) GS Software (PRP-P-MZ), Released Version 12.0(22)S
Copyright (c) 1986-2002 by cisco Systems, Inc.
Compiled Sat 10-May-02 06:02a

Step 6 Observe the system startup banner. When you start up an unconfigured system for the first time, the system automatically enters the setup facility, which determines which interfaces are installed and prompts you for configuration information for each one.

On the console screen, after the system displays the system banner and hardware configuration, the following System Configuration Dialog prompt appears:

         --- System Configuration Dialog ---

At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.

Continue with configuration dialog? [yes/no]:

Step 7 You can either proceed with the setup facility or exit from setup and use configuration commands to configure global (system-wide) and interface-specific parameters.


You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until they are configured.

The interface-specific LEDs on line cards might not go on until after you configure the line card interfaces. To verify correct operation of each interface, complete the first-time setup procedures and configuration, then refer to the LED descriptions in the configuration notes for each line card to check the status of the interfaces.

Verifying Interface Status

The status LEDs on the PRP indicate system and PRP status, which Flash disk slot is active, which Ethernet connection is in use, and what is occurring on the Ethernet interface. This section provides functional descriptions of the status LEDs on the PRP-1 and PRP-2 (see Figure 8 and Figure 9) and the processes you should observe.

Figure 8 PRP-1 LEDs (Partial Front Panel View)

The PRP-1 has the following LED indicators:

Two Flash disk activity LEDs, one for each Flash disk slot (labeled SLOT-0 and SLOT-1)—Identify which of the two Flash disk slots 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.

Figure 9 PRP-2 LEDs (Partial Front Panel View)

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)—Identify which of the Flash disk slots 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

Upgrading to the PRP

This section details how to upgrade from the GRP to the PRP. The procedures described are the same whether you are upgrading to a PRP-1 or PRP-2.

Upgrading to the PRP Without Rebooting the Router

Upgrading to the PRP With Rebooting the Router

Differentiating Between PRP-1 and PRP-2

Upgrading to the PRP Without Rebooting the Router

To upgrade to the PRP from the GRP without interruption of service, you must have support for High Availability in your router. This means that two GRPs must be installed in the router and the redundancy must be set to either SSO or RPR+ mode. To configure the redundancy, use the redundancy command in global configuration mode. To view the redundancy configuration on the RPs, use the show redundancy command.

To upgrade to the PRP using High Availability, use the following procedure:


Step 1 Verify that there are two GRPs in the router, both running the same Cisco IOS version, and that the router is configured for SSO or RPR+ redundancy. The show redundancy command indicates the redundancy mode as well as the Cisco IOS version running on the GRPs. Take note of the Cisco IOS version running on the GRPs (12.0(26)S in this example).

        Configuration register = 0x2102

Step 2 Remove the Flash disk from the PRP card and install it into slot 1 of the active RP. The following message will be displayed; do not format the disk.

22:21:31: %PCMCIAFS-5-DIBERR: PCMCIA disk 1 is formatted from a 
different router or PC. A format in this router is required before an 
image can be booted from this device


Note If your router is running an image prior to Cisco IOS Release 12.0(25)S2, you are advised to insert the Flash disk into slot 1 of the standby RP, and not the active RP.


Step 3 Verify the disk contents using the dir disk1: command (or the dir stby-disk1: command if the Flash disk is in the standby RP).

Router# dir disk1:
Directory of disk1:/

    1  -rw-    17329392   Dec 3 2003 11:44:46 +00:00  
c12kprp-p-mz.120-27.S

63832064 bytes total (46465024 bytes free)

Step 4 If the Cisco IOS version is not the same as the one running on the GRPs, delete the image from the disk using the delete disk1: filename command (or the delete stby-disk1:filename command if the Flash disk is in the standby RP). If the image is correct, continue with Step 7.


Note Before you delete the image, verify that you have a copy of this image on another disk or at another location.


Step 5 Use the copy tftp: disk1: command to copy onto the Flash disk a PRP image that is the same as that currently running on the GRPs (in this example, 12.0(26)S). PRP images are titled c12kprp-<feature set>-<compression>.120-<release id>. You will receive an error that the PRP image is not executable on the GRP. When prompted to abort the copy, type n.

Use the copy tftp: stby-disk1: command if the Flash disk is in the standby RP.

Router# copy tftp: disk1:
Address or name of remote host [172.16.16.254]?
Source filename [c12kprp-boot-mz.120-26.S]? c12kprp-p-mz.120-26.S
Destination filename [c12kprp-p-mz.120-26.S]?
Accessing tftp://172.16.16.254/c12kprp-p-mz.120-26.S...
%Warning: File not a valid executable for this system
Abort Copy? [confirm] n

Step 6 To verify that the image has been copied correctly, verify the MD5 hash for the new image on disk1:. To do this, use the command verify /md5 disk1image-name. The resulting string should be compared against the MD5 hash value posted on the Software download page on Cisco.com.

Step 7 Place the Flash disk referred to in Step 5 back into the PRP Flash disk drive.

Step 8 Repeat Step 2 through Step 7 for the second PRP to be installed as standby.

Step 9 Remove any existing boot system commands from the running configuration by using the command no boot system. This will make the PRP boot from the image on the Flash disk.

Step 10 Remove the standby GRP from the router.

Step 11 Insert the PRP into the router in place of the standby GRP. The PRP will now begin to load the Cisco IOS image contained on the Flash disk. At this stage, even though a GRP and a PRP are in the chassis simultaneously, the router remains in SSO or RPR+ mode because the RPs are running the same image.


Note The PRP and GRP must both be running the same Cisco IOS version; otherwise, the redundancy will revert to RPR mode and there may be traffic disruption.


Step 12 Remove the active GRP. Because the router is configured for High Availability (SSO or RPR+ mode), the switchover to the PRP will take advantage of the High Availability feature and there will be minimum disruption in operation.

Step 13 Insert the standby PRP into the chassis, also with the same Cisco IOS image loaded onto its Flash disk. Now both PRPs will be up and running the same image that was originally running on the GRPs. At this point you can upgrade the Cisco IOS version on the PRPs to the version shipped with the cards.


Note You must have the same Cisco IOS image loaded on the Flash disks of the two PRPs. If different versions are loaded, the redundancy will revert to RPR and there
