Chapter 6 Maintaining the Cisco 7204
Reformatting a Flash Memory Card
Step 5
Use the following series of commands to designate the file new.image (which is on the Flash memory
card in slot 0) as the default boot image:
Router# config t
Router(config)# no boot system
Router(config)# boot system flash slot0:new.image
Router(config)# ^z
Router# copy running-config startup-config
Router# reload
When the system reloads, it will boot the file new.image from the Flash memory card in slot 0.
This completes the procedure for copying bootable images between Flash memory cards.
Reformatting a Flash Memory Card
Depending on the circumstances, you might need to use a Flash memory card from another system to
copy images or backup configuration files; however, you cannot boot from a Flash memory card that was
formatted on another type of system. You must reformat the card before you can use it as a boot source.
(Use only Intel Series 2+ Flash memory cards.)
Note
To avoid potential problems when inserting spare Flash memory cards in your Cisco 7204, we
recommend that you reformat all of your Flash memory cards on a Cisco 7204 running one of the
recommended Cisco IOS software releases listed in Software Advisor.
Caution
The following formatting procedure erases all information on the Flash memory card. To prevent the loss
of important data that might be stored on a Flash memory card, proceed carefully. If you want to save
the data on a Flash memory card, copy the data to a server before you format the card.
The reformatting procedure assumes the following:
•
You have already booted your Cisco 7204.
•
You have access to a TFTP server (meaning you know its name and have connectivity to it) and at
least one interface is available over which you can access this server, or a secondary Flash memory
card available in slot 0 or slot 1 onto which you can copy files.
Note
To ensure access to a TFTP sever, you will need to configure at least one network interface
using the setup command facility. For instructions on using this procedure, refer
to
Chapter 4, “Performing a Basic Configuration of the Cisco 7204.”
•
You know the filename of the image you want you want to copy to the TFTP server or onto the
secondary Flash memory card.
Use the following procedure to reformat a Flash memory card:
Step 1
Insert the Flash memory card into slot 0. (If slot 0 is not available, use slot 1.) (Refer to the earlier section
“Installing and Removing a Flash Memory Card” section on page 6-7
.)
