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.

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.
