Juniper EX3400 User Manual

3. At the Junos OS login prompt, type root to log in. You don't need to enter a password. If the software boots before
you connect your laptop or desktop PC to the console port, you might need to press the Enter key for the prompt to
appear.
NOTE: EX switches running current Junos software are enabled for Zero Touch Provisioning (ZTP). However,
when you configure an EX switch for the very first time, you’ll need to disable ZTP. We show you how to do
that here. If you see any ZTP-related messages on the console, just ignore them.
