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, as does the NPE-G2.
Note To avoid potential problems when you install spare Flash Disks or PC Cards in your Cisco 7206VXR, 
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 Table 1-31, Table 1-32, and Ta ble 1-33) during 
your regularly scheduled service times. The online document Memory Replacement Instructions for the 
Network Processing Engine or Network Services Engine and 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.
Note For procedures that explain the use of the Flash Disk or CompactFlash Disk, refer to the online Using 
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 
Input/Output Controller document. This document is available on the Documentation DVD and on 
Cisco.com.
For NPE-G2 and 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, see the 
Network Processing Engine and Network Services Engine
