PCMCIA Flash Disks and Flash Memory Cards
The Cisco 7204 supports up to two installed PCMCIA Flash Disks or two Flash memory cards.
Note
To avoid potential problems when inserting spare Flash Disks or Flash memory cards in your
Cisco 7204, we recommend that you reformat all of your Flash Disks or Flash memory cards on a
Cisco 7204 running one of the recommended Cisco IOS software releases. The chapter
Chapter 6,
“Maintaining the Cisco 7204”
contains instructions that explain how to reformat a Flash memory card.
Flash memory (Flash Disks or 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 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 PCMCIA Flash Disk, refer to the
Using the Flash Disk
document .
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 and
Input/Output Controller
document.
The preceding documents are available on Cisco.com. Instructions for installing and removing a Flash
memory card are also contained in the
“Installing and Removing a Flash Memory Card” section on
page 6-7

Chapter 6, “Maintaining the Cisco 7204”
