Flash Disks and Flash Memory Cards
The Cisco 7206VXR supports up to two installed Flash Disks or two Flash
memory cards.
Note To avoid potential problems when you install spare Flash Disks or
memory cards in 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 or Network Services Engine and the Input/Output
Controller that shipped with your system explains how to reformat a
Flash memory card.
With Flash memory (Flash Disks or Flash memory cards and the Flash SIMM on
the I/O controller) you can 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.
Note For procedures that explain the use of the Flash Disk, refer to the
Using the Flash Disk document that accompanies every Flash Disk
shipped from the factory.
For procedures that explain how to replace the main, Flash, and
ROM monitor memory, refer to the Memory Replacement
Instructions for the Network Processing Engine or Network Services
Engine and the Input/Output Controller document that shipped with
your system. Documents are also available on the Documentation
CD-ROM and on CCO.
