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.

a valid Cisco IOS image in Flash memory and a configuration file in NVRAM. The first time you boot your router, you will need to configure the router interfaces and then save the configuration to a file in NVRAM. Proceed to the next section, "Configuring the Router," for configuration instructions - Cisco 2524 | Configuration Guide - Page 3

the AutoInstall process: Step 1 Attach the WAN cable to the router. Step 2 Turn ON power to the router. The router will load the operating system image from Flash memory. If the remote end of the WAN connection is connected and properly configured, the AutoInstall process will begin. If AutoInstall - Cisco 2524 | Configuration Guide - Page 6

CHAPTER
Configuring the Cisco 2524 and Cisco 2525 Routers
4-1
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.
