Cisco Cisco MGX 8880 Media Gateway Release Notes

The RPM-XF bootflash is used to store boot image, configuration, and run-time files. Erasing the boot 
image from the flash prevents the card from booting.

The RPM-XF boot image, which is shipped loaded on the flash, works for all RPM-XF Cisco IOS 
images; therefore, there is no reason to delete or move the factory installed boot image.

To avoid unnecessary failures that require card servicing, remember the following:

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.

If the boot file remains intact in the first position on the flash, the RPM-XF boots successfully.

If the bootflash is corrupt, use the tftpdnld command described in the Cisco MGX Route Processor 
Module (RPM-XF) Installation and Configuration Guide or the xmodem procedure described in the 

 to download a new boot 

image.

If you add more than 11 VISM cards to an MGX chassis with RPM-XF cards, this requires that you 
enable the expanded memory option on the PXM45/B. The command to enable this option is 
cnfndparms (option 4). This expanded memory option does not have an impact on chassis performance 
and allows more connections.
