Cisco Systems 7500 Series manual Copying Files to Flash Memory

Chapter 4 Performing a Basic Configuration of the System

Using the Flash Memory Cards in the RSPs

Copying Files to Flash Memory

You might need to copy a new image file to Flash memory whenever a new Cisco IOS software release or maintenance release becomes available.

Caution You cannot copy a new image into Flash memory while the system is running from Flash memory.

We recommend that you upgrade Cisco IOS software images in Flash memory one at a time; do not delete all known-good images at one time. Also, upgrade PC Card-based Flash memory separately from onboard Flash memory, to avoid losing important Cisco IOS software images that are known to be good. (The onboard Flash memory is referred to as the bootflash.)

Use the command copy tftp:filename [bootflash slot0 slot1]: filename for the copy procedure, where

tftp:filename is the source of the file and [ bootflash slot0 slot1]: filename is the destination in onboard Flash memory or on either of the Flash memory cards.

An example of the copy tftp:filename command follows for a file in the Flash memory card in PC Card slot 0:

Router# copy tftp:myfile1 slot0:myfile1

20575008 bytes available on device slot0, proceed? [confirm] Address or name of remote host [10.1.1.1]?

Note In the preceding example, the exclamation points (!!!) appear as the file is downloaded, and the “C” characters signify calculation of the checksum, which is a verification that the file has been correctly downloaded to the Flash memory card.

Making a Flash Memory Card Image Bootable

Use the following series of commands to make a Flash memory card image bootable. (In this example, the filename is new.image.) Note that the config-registercommand is part of the sequence because the configuration register must be set to 0x2102 to enable loading an image from Flash memory.

Router# config terminal

Router(config)# no boot system

Router(config)# boot system flash slot0:new.image

Router(config)# config-register 0x2102

Crtl-Z

Router# copy running-config startup-config

Router# reload

When the system reloads, it will boot the image new.image from the Flash memory card in slot 0.
