If you store the startup images on the USB disk, do notremove the USB disk during the startup process.Unless otherwise stated, "IRF fabric" refers to both a standalone IRF fabric and the parent fabric inan IRF 3 system.In an IRF 3 system, the master device on the parent fabric is also the master of the entire system.For more information about IRF 3, see IRF Configuration Guide.boot-loader fileUse boot-loader file to specify startup software image files.Syntaxboot-loader file boot boot-package system system-package [ feature feature-package&<1-30> ]{ all | slot slot-number } { backup | main }boot-loader file ipe-filename { all | slot slot-number } { backup | main }ViewsUser viewPredefined user rolesnetwork-adminParametersboot boot-package: Specifies the file path of a .bin boot image file, a case-insensitive string.

If you specify this keyword, the system copiesdevice-specific images automatically to the root directory of the storage medium on each device. Fora successful upgrade, make sure the specified files include the upgrade images for all devices.
