Configuring the Cisco 2524 and
Cisco 2525 Routers
4
This chapter describes how to configure the Cisco 2524 and Cisco 2525 routers and
contains the following sections:
• Booting the Router for the First Time
• Configuring the Router
• Specifying the Boot Method
• Checking the Configuration Settings
• Getting More Information
This chapter provides just enough information to get the router up and running. For
Cisco IOS Release 11.0 and earlier releases, refer to the Router Products Configuration
Guide for additional configuration information. For Cisco IOS Release 11.1 and later
releases, refer to the Configuration Fundamentals Configuration Guide.
Booting the Router for the First Time
Each time you power on the router, it goes through the following boot sequence:
1 The router goes through power-on self-test diagnostics to verify basic operation of the
CPU, memory, and interfaces.
2 The system bootstrap software (boot image) executes and searches for a valid Cisco IOS
image (router operating system software). The source of the Cisco IOS image (Flash
memory or a Trivial File Transfer Protocol [TFTP] server) is determined by the
configuration register setting. The factory-default setting for the configuration register
is 0x2102, which indicates that the router should attempt to load a Cisco IOS image
from Flash memory.
