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)—The latest 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—A flash 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—A Trivial 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.
