Booting the RPM-PR
RPM-PR Bootflash Precautions
The RPM-PR bootflash is used to store boot image, configuration and “run time” files. The Flash stores
and accesses data sequentially, and the RPM-PR boot image must be the first file stored to successfully
boot the card. Erasing the boot image or moving it from the first position on the Flash will cause the card
to not boot.
The RPM boot image, which comes loaded on the Flash, will work for all RPM IOS images. Therefore,
there is no reason to ever delete or move the factory installed boot image.
Note Erasing or moving the boot image can cause RPM-PR boot failure. When this happens, the RPM must
be returned to Cisco and reflashed.
In order to avoid this unnecessary failure, requiring card servicing, you should
• Never erase the boot file from the RPM Flash
• Never change the position of the boot file on the RPM Flash
• Use care when “squeezing” the Flash to clean it up.
As long as the boot file remains intact in the first position on the flash, the RPM will successfully boot.
Verifying the IOS Files on Bootflash
Enter the show bootflash command to verify the IOS files on the bootflash. The following screen
displays the RPM-PR command sequence.

Verifying the IOS Files on the PXM-45 x: Drive
The IOS image can be stored on the PXM-45 hard drive. To confirm this, make sure you are in the C:FW
directory. Enter the ll command to list the contents of the directory. You should see a file with a name
beginning with rpm-js-mz, which is the IOS image.
Tip Copy the RPM-PR Cisco IOS image into the RPM C: directory (not the E: directory) of the PXM-45
hard disk with the filename specified in the RPM-PR boot command.
The following screen displays the PXM C:FW content listing.
M8850_LA.8.PXM.a > cd FW
