Field-Replaceable Units Chapter 1 Cisco 7200 VXR Product Overview Figure 1-30 Cisco 7200 VXR Chassis-7206VXR Shown 5 6 3 4 1 2 Cisco 7200 Series VXR 0 14628 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 Table 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 Installation and Configuration document at http://www.cisco.com/en/US/products/hw/routers/ps341/products_installation_guide_book09186a0080 551c34.html. 1-52 Cisco 7200 VXR Installation and Configuration Guide OL-5013-09
