Chapter 1 Product Overview
Flash Disks and Flash Memory Cards
The Cisco 7206 supports up to two installed Flash Disks or two Flash memory cards.
Note To avoid potential problems when inserting spare Flash Disks or Flash memory cards in your
Cisco 7206, we recommend that you reformat all of your Flash Disks or Flash memory cards on a
Cisco 7206 that is running one of the recommended Cisco IOS software releases listed in Software
Advisor. (Flash Disks should be reformatted with a Cisco IOS 12.0 T software image.) The
"Reformatting a Flash Memory Card" section on page 5-12
reformat a Flash memory card.
Flash memory (Flash Disks or Flash memory cards and the Flash SIMM on the I/O controller) allows
you to remotely load and store multiple system and boot helper images. You can download a new image
over the network and then add the new image to Flash memory or replace existing files. You can also
transfer images between Flash Disks or Flash memory cards and the onboard Flash memory. You can
then boot the router either manually or automatically from any of the stored images. Flash memory can
also function as a TFTP server to allow other routers to boot remotely from stored images or copy them
into their own Flash memory.
For procedures that explain the use of the Flash Disk, refer to the Using the Flash Disk document that
Note
accompanies every Flash Disk shipped from the factory.
For procedures that explain how to replace main, Flash, and ROM monitor memory in Cisco 7200 series
routers, refer to the Memory Replacement Instructions for the Network Processing Engine or Network
Services Engine and Input/Output Controller document that accompanies every memory option (main,
Flash, and ROM monitor) that is shipped from the factory as a FRU.
The preceding documents are also available on Cisco.com. Instructions for installing and removing a
Flash memory card are also contained in the section
