51.7 Dual Image Files

The management switching card supports dual firmware images. By default, the management
switching card uses firmware ras-0 while the second firmware file is named ras-1. This allows immediate
rollback on system boot up in case of a corrupt firmware image.
Use the show version [flash] command to display the version of the running firmware on the active
management switching card. Optionally, display the version of the currently installed firmware on the
flash memory.
Use the show msc command to display the versions of the running firmware on the active and standby
management switching cards.
Use boot image <1|2> to have the (active) management switching card update (1) the ras image or
(2) the ras-1 image when you upload firmware.
