General configuration restrictions and guidelines
When you manage the next-startup configuration files, follow these restrictions and guidelines:
Save the next-startup configuration files to the root directory of the default storage medium. The device loads startup configuration files only from the default storage medium. You can access the Boot menus to specify the built-in flash memory or the USB disk as the default storage medium.
In a multichassis IRF fabric, make sure all member devices use the same type of storage medium as the default storage medium.
If the startup configuration file is on a USB disk, do not remove the USB disk during the startup process. If you remove the USB disk, one of the following events will occur:
In a single-chassis IRF fabric, the device will start up with the factory defaults.
In a multichassis IRF fabric, the device will leave the IRF fabric at startup and run the factory defaults.
