When the switch boots from the storage media (removable media, CompactFlash card, or hard disk) it
expands its search in the /config directory of the roung plaorm for the following les in the following
order: juniper.conf (the main conguraon le), rescue.conf (the rescue conguraon le), and
juniper.conf.1 (the rst rollback conguraon le). When the rst conguraon le is found that can be
loaded properly, the search ends and the le is loaded. If none of the le can be loaded properly, the
roung plaorm does not funcon properly. If the switch boots from an alternate boot device, Junos OS
displays a message indicaon this when you log in to the switch.
