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 t

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.

Chapter 4 System Startup and Basic System Configuration Manually Booting the System You do not need to configure the network interfaces immediately, but you cannot connect to a network until you configure the interfaces for operation in your network environment. For configuration information, see the “Configuring the Router” section on page 4-14. Note The interface-specific LEDs on the line cards may not power on until you configure the line card interfaces.

Chapter 4 System Startup and Basic System Configuration Manually Booting the System Caution Use the boot flash command with care. Make sure that the flash memory card inserted in slot 0 contains a valid Cisco IOS software image; otherwise, you could instruct the system to boot an invalid image from the flash memory card. Before entering a boot command, always enter the dir slotn: command to examine the contents of a flash memory card. Table 4-3 Boot Commands Command Purpose boot (No argum

Chapter 4 System Startup and Basic System Configuration Configuring the Router Note If you did not change the configuration register setting, the next reload will revert to the default configuration register setting (0x0102). This setting causes the system to boot Cisco IOS software from a flash memory card inserted in slot 0 the next time you boot the router. See the “Configuring the Software Configuration Register” section on page 4-31 for additional information. Configuring the Router Y
