Recommendations
Cisco highly recommends that all images used on your Cisco 6400 system have the same version level,
specifically:
• Use the same release versions for the system images on the NRP and the NSP.
• Use the same version level for the system and boothelper images for both the NRP and NSP.
The NSP uses the same file (c6400s-wp-mz) as both the system image and boothelper image. Make
sure you download the new NSP image to boot flash and a PCMCIA disk (disk0: or disk1:).
The NRPs use two separate images for the system and boothelper images:
– c6400r-boot-mz—Boothelper image to load in boot flash
– c6400r-g4p5-mz—NRP-1 system image to load in Flash
– c6400r2sp-g4p5-mz—NRP-2 system image to load in Flash
