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 roung plaorm for the following les in the following
order: juniper.conf (the main conguraon le), rescue.conf (the rescue conguraon le), and
juniper.conf.1 (the rst rollback conguraon le). When the rst conguraon 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
roung plaorm does not funcon properly. If the switch boots from an alternate boot device, Junos OS
displays a message indicaon this when you log in to the switch.
