When installing a new C7200-I/O-2FE/E(=) into a 7200(VXR) with a NPE-225(=), the boot flash will not be recognized on the I/O controller. If the router is configured to net boot, it will fail to boot and will eventually hang. If IOS is loaded on the PCMCIA flash, the router will eventually boot.
Note: The C7200-I/O-2FE/E(=) was not designed to work in a non-VXR chassis. This controller is only supported in VXR chassises.
When the C7200-I/O-2FE/E was released, a ROMMON upgrade was required for the NPE-225 so that the boot flash would be recognized on the I/O controller. Systems with NPE-225 hardware versions lower than 1.3 will not recognize the boot flash on the I/O controller. NPE-225 hardware version 1.3 or higher will fix this issue.
If boot-up on a 7200 (VXR) system containing an NPE-225 (version 1.2 or lower) and the C7200-I/O-2FE/E controller is attempted, the system will fail to boot from bootflash. The system will eventually boot from slot0. The router will display the following message before booting from slot0:
getdevnum warning: device "boot flash" has size of zero getdevnum warning: device "boot flash" has size of zero open: read error...requested 0x4 bytes, got 0xffffffff trouble reading device magic number boot: cannot open "bootflash:" boot: cannot determine first file name on device "bootflash:"
If the router is configured to net boot, the same message will be displayed and the router will eventually hang.
The workaround is to copy Cisco IOS® to the PCMCIA flash and configure the system to boot from the PCMCIA flash. For instructions on this process, please refer to the following documents on CCO:

Common Problems in Installing Images Using TFTP or an RCP Server
If the router is setup to perform a net boot, the net boot will fail. A new NPE-225 (hardware version 1.3 or higher) is required to fix this problem. Please use the standard RMA process to get the replacement NPE-225.
The show c7200
IOS command can be used to determine the revision of NPE-225 present in the chassis as shown below.
Please note that the NPE-225 is comprised of two 73-level assemblies. These two 73-level assembly numbers correspond to the Network Control Board (NCB) and the Processor Engine Module (PEM). The PEM makes the NPE-225 unique from the NPE-150. The NCB of the NPE is common to both the NPE-150 and NPE-225. This is the part affected by the fix for this problem and its 73-level number is shown below in the sample show c7200
command output highlighted in bold text. Affected NPE-225 boards have the 73-level part number 73-3453-04 or earlier versions. Corrected versions, as shown, have the part number 73-3453-05 or later.
Note: The suffix (last two digits of the part number) is the version number referenced.
