Series VXR
CompactFlash Disks, Flash Disks and PC Cards
The Cisco 7206VXR supports up to two installed Flash Disks or two PC Cards, also called Flash
memory cards. The NPE-G1 supports one CompactFlash Disk.
To avoid potential problems when you install spare Flash Disks or PC Cards in your Cisco 7206VXR,
Note
we recommend that you reformat all your Flash Disks or PC Cards on a Cisco 7206VXR that is running
the Cisco IOS release recommended for your system (see
service times. The online document Memory Replacement Instructions for the Network Processing
Engine or Network Services Engine and the Input/Output Controller explains how to reformat a PC Card.
With Flash memory (Flash Disks, PC Cards, and the Flash SIMM on the I/O controller, or the
CompactFlash Disk on the NPE-G1) 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 PC 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.
For procedures that explain the use of the Flash Disk or CompactFlash Disk, refer to the online Using
Note
the Flash Disk document.
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 Cisco.com.
For NPE-G1 pre-installation information, which requires copying the running configuration from the I/O
controller to a Flash Disk or TFTP server before inserting the NPE-G1 into the Cisco 7200 VXR router,
