Chapter 4 System Startup and Basic System Configuration

Sources of Cisco IOS Software

This chapter provides you with the information to configure your system so that it can access the network or enable other hosts in the network to access your system remotely by means of a Telnet connection. Detailed configuration procedures are beyond the scope of this document, but you can find more information in the “Post-Installation Procedures” section on page 4-63.

Sources of Cisco IOS Software

A default Cisco IOS software image for your system is available through any of the following internal or external sources:

Onboard flash memory on the Route Processor (RP)—Thelatest Cisco IOS software image is preloaded into the flash memory, and it is a single inline memory module (SIMM). Flash memory is also referred to as nonvolatile random access memory (NVRAM). NVRAM retains its contents when you power off the system.

Flash memory card—Aflash memory card (sometimes referred to as a flash disk) inserted in a PCMCIA slot on the RP can serve as an external storage medium for a default Cisco IOS software image.

TFTP server—ATrivial File Transfer Protocol (TFTP) server in the network can also function as an external source of a default Cisco IOS software image. You can download a valid Cisco IOS software image from such a remote host using a Telnet connection.

Preconfiguration Requirements

Before you configure your system, confirm the following:

All cards are securely installed.

All interface cable connections are secure and use cable strain relief where provided.

All source power cables are securely fastened to the PDUs, and are connected to the appropriate power source.

Chapter 4 System Startup and Basic System Configuration

Boot Process Overview

A terminal device is connected to the console port on the RP, powered on, and configured for 9600 bps, 8 data bits, no parity, and 2 stop bits (9600, 8N2).

Note You must connect a terminal to the RP to perform the initial configuration of the router.

The flash memory card that shipped with your router is installed in slot 0 of the RP. The software configuration register is set to 0x0102 (default), causing the system to boot automatically from the Cisco IOS software image stored on the flash memory card.

After you complete the above, proceed to the following section to start the router.

Boot Process Overview

The following sequence summarizes a typical boot process.

1.You power on the router.

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

3.The RP determines the router configuration by sending a message over the MBus requesting all installed devices to identify themselves. Their responses provide the RP with slot numbers, card, and component types.

4.The RP, line cards, switch fabric cards (CSCs and SFCs), and alarm card are then powered on.

5.The power-on-resetlogic of the RP is delayed to allow power for both local and CSC clocks to stabilize.

6.After the power-onreset logic is released, the RP begins to execute the ROM monitor software.

If the ROM monitor is configured to autoboot, the system automatically loads and boots the Cisco IOS software.

If the ROM monitor is not configured to autoboot, you must boot the Cisco IOS software manually.

Powering On the Router and Observing the Boot Process

7.When the Cisco IOS software boots, it polls all other cards in the system, powers them on, and loads the Cisco IOS software they require.

8.The RP waits for all other cards to finish their boot processes.

Powering On the Router and Observing the Boot

Process

The first time you start the router, observe the following conditions:

Step 1 Switch on all the circuit breakers that control power to the router.

Step 2 Observe the power entry module LEDs:

AC PEMs—Thegreen PWR OK LED should be on and the power supply fan operating.

DC PEMs—Thegreen PWR OK LED should be on and the power supply fan operating.

Step 3 Check the blower module:

Ensure that the green OK LED is on.

Listen for the blowers in the blower modules; you should hear them operating immediately. In a noisy environment, the blowers may be difficult to hear. You can place your hand in front of the exhaust vents near the top rear of the chassis to verify that the blower is operating.

Step 5 Observe the status of the RP interfaces (seeFigure 4-2 for the GRP andFigure 4-3 for the PRP).

The LEDs on the RP show system status, the active flash memory card slot, the Ethernet connection in use, and the status of the Ethernet interface.

PCMCIA flash memory card slot LEDs (labeled Slot-0andSlot-1)are on when the slot is accessed.

PRP—RJ-45Ethernet port LEDs show the port activity:

Step 6 During the line card boot process, observe the alphanumeric LED displays on each line card (Figure 4-4).

Note The line card boot process occurs immediately after the RP boot process.

The system attempts to boot identical line cards in parallel. Further, the system boots line cards as soon as they are powered on and become available. Each line card displays a sequence similar to those shown in Table 4-2.

Chapter 4 System Startup and Basic System Configuration

Powering On the Router and Observing the Boot Process

Step 7 The router automatically boots using the default image (if a flash memory card containing a valid Cisco IOS software image is inserted in slot 0 and the software configuration register is set to 0x0102).

As the router boots the Cisco IOS software image, a system banner similar to the following appears:

Cisco Internetwork Operating System Software

IOS (tm) GS Software (GSR-P-M),Experimental Version 12.0(20010120:204554) [gha]

Copyright (c) 1986-2001by cisco Systems, Inc. Compiled Sat20-Jan-0118:34 by ghall

Note The system banner depends on the image version of the Cisco IOS software that the system is running. Your system banner might be different than the examples throughout this chapter.

If the ROM monitor prompt (rommon>) displays, the router did not find a valid system image or the boot sequence was interrupted, and the system entered read-onlymemory (ROM) monitor mode.

In this case, you must boot a Cisco IOS software image manually by issuing the boot command.

For information on locating a valid Cisco IOS software image, refer to the “Locating a Valid Cisco IOS Software Image” section on page 4-12.

For information on using one of the various forms of the boot command, refer to the“Booting from the Cisco IOS Software Image” section on page 4-12.

After manually booting the router, continue to Step 8.

Step 8 When you start an unconfigured system for the first time, the system automatically starts the system configuration dialog. The interactive script prompts you through the steps to create a router configuration file defining basic system operation parameters.

---System Configuration Dialog---

Continue with configuration dialog? [yes/no]:

The router uses the system configuration file to activate network connections to the RP so the router can be administered from a remote location, or to activate the line card network interfaces. After the initial configuration, the RP and line cards can communicate with external networks.
