Managing a Nonvolatile File System
117381-A Rev. A 4-3
Using Multiple Memory Cards
This section describes how to manage multiple memory cards on the router. You
may want to allocate them as follows:
• Keep one card as the primary card used for booting.
• Use another card for redundancy.
If you are providing redundancy, be sure to copy files that you modify to the
redundant volumes.
• Use another card as temporary storage for log files and test configuration files.
