Before you install the Model 5782 module in the chassis for the first time, you

You need only one flash memory card for any number of routers in a chassis with
a PPX backplane. Additional routers can use the image and configuration files on
the card. If you install more than one flash memory card for redundancy, make
sure that the version of the software and the configuration files are the same on all
cards.
