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. 26 Performance Route Processor Installation and Configuration Guide OL-11656-01 Checking the Installation 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.

For example, Microcode Version 1.17 displays as 0117. 1 RP RDY The ROMMON for this PRP is enabled and recognized by the system. ACTV RP 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. Performance Route Processor Installation and Configuration Guide OL-11656-01 Checking the Installation 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 OL-11656-01 Performance Route Processor Installation and Configuration Guide 29 Checking the Installation • b flash disk0: filename—Boots the file filename from the Flash disk in Flash card slo...
