Field-Replaceable Units
Flash Disks and Flash Memory Cards
The Cisco 7206VXR supports up to two installed Flash Disks or two Flash memory cards.
Note
your Cisco 7206VXR, we recommend that you reformat all your Flash Disks or memory
cards on a Cisco 7206VXR that is running the Cisco IOS Release recommended for your
system (see Table 1-1) during your regularly scheduled service times. The document
Memory Replacement Instructions for the Network Processing Engine and the
Input/Output Controller that shipped with your system explains how to 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 SIMM. 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.

Input/Output Controller document that shipped with your system. Documents are also
available on the Documentation CD-ROM and on CCO.
