Important Information • Upgrading Chopper FPGA on PRP-2, page 80 • Regulatory, Compliance, and Safety Information, page 83 • Obtaining Documentation, page 88 Important Information This section contains information about the following hardware and software requirements: • Router Information, page 2 • Cisco IOS Software Requirements, page 3 • Hardware Revision Requirements, page 4 • Related Documentation, page 5 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 2 Performance Route Processor Installation and Configuration Guide OL-11656-01 Important Information 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. Performance Route Processor Installation and Configuration Guide OL-11656-01 3 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. 4 Performance Route Processor Installation and Configuration Guide OL-11656-01 Product Overview Related Documentation For additional information on the PRP, refer to these publications: • Performance Route Processor Software Configuration in Cisco 12000 Series Internet Routers • Route Processor Redundancy Plus for the Cisco 12000 Series Internet Router • Cisco IOS Release 12.0S Release Notes for Cisco 12000 Series Internet Router • Cisco IOS Configuration Fundamentals Configuration Guide • Cisco IOS Configuration Fundamentals Command Reference See the “Obtaining Documentation” section on page 88 for information on how to obtain these publications.
