Flash Memory Card
Copying a Bootable Image onto a Flash Memory Card
After you have formatted a new flash memory card, you can copy a bootable image onto it. To copy an
image, use the following procedure, which assumes the following:
•
You have an I/O controller with a good image in the onboard flash memory single in-line memory
module (SIMM) so that you can start the Cisco uBR7200 series universal broadband router.
•
The bootable image you want to copy to the flash memory card exists on a TFTP server to which
you have access (meaning that you know its name and have connectivity to it), and at least one
interface is available over which you can access this server.
Note
To ensure access to a TFTP server, you must configure at least one network interface on your
Cisco uBR7200 series router. For instructions on using this procedure, refer to the
Cisco uBR7200 Series
Software Configuration Guide
at the following URL:
http://www.cisco.com/en/US/docs/cable/cmts/ubr7200/configuration/guide/cr72scg.html
•
You know the filename of the image you want to copy onto the flash memory card.
To copy a bootable file (called new.image in the following examples) onto the flash memory card:
Step 1
Boot the router and allow it to initialize.
Step 2
Insert an unformatted flash memory card and format it using the procedure in the
“Formatting a New
Flash Memory Card” section on page 5-9
. Then proceed to Step 3.
Note
If you have already formatted a flash memory card, you can use it instead; however, you cannot boot
from a flash memory card that was formatted on another type of system. You must reformat the card to
use it as a boot source. To avoid potential problems when inserting flash memory cards in your router,
we recommend reformatting all of your flash memory cards on a router running
Cisco IOS Release 12.0(5)T1 or later during your regularly scheduled service times. The
“Reformatting
a Flash Memory Card” section on page 5-12
contains instructions that explain how to reformat a flash
memory card.
Step 3
Copy the new image (new.image) to the flash memory card and make this image the default boot image.
Then reboot the router using the following series of commands:
