LCD Panel Modes
The LCD operates in four modes: boot, idle, status, and maintenance.
The LCD operates in boot mode during switch reboot.
The boot mode displays the key milestones in the switch boot process. The boot mode
does not have any menu options. After the boot process is complete, the LCD
automatically reverts to the Idle menu.
In the idle mode, line two of the Idle menu displays the network ports’ Status LED modes
and the total number of alarms in the system. The number of alarms is updated every
second.
The status mode allows you to get status information for the following items:
• Switch fabric in Switch Fabric and Routing Engine (SRE) modules in EX8208 switches
• Routing Engine (RE) and switch fabric in Switch Fabric (SF) module(s) in EX8216
switches
• Power supplies
• Fan tray(s) and chassis temperature
• Junos OS version installed
