Description

Set the switch to unattended mode for U-Boot to prevent unauthorized access to the system before the JUNOS OS login prompt appears. In unattended mode, access to the loader CLI is blocked, as well as recovery mechanisms such as password recovery by using single-user mode and booting the switch by using a USB flash drive. In order to access the CLI in U-Boot mode, the user must enter a boot-loader password that has been previously configured.

Note:

If the root password is lost while the switch is in unattended mode, the switch must be reset to the factory default configuration using the LCD panel. For more information see Reverting to the Default Factory Configuration for the EX Series Switch.
