LCD Panel Modes

The LCD panel operates in four modes: boot, idle, status, and maintenance.
The LCD panel 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 panel automatically reverts to the Idle menu.
The first line of text on the LCD panel displays the slot number, the role of the switch, and hostname. For
a standalone EX4500 switch, the slot number is always 00, and the role is always RE.
In an EX4500 switch that is a member of a Virtual Chassis, the first line of the LCD panel displays:
The slot number (the member ID for the Virtual Chassis member)
Role of the switch in a Virtual Chassis (RE for primary, BK for backup, and LC for linecard member)
Hostname
In the idle mode, the second line of text on the LCD panel displays the mode of the network ports' Status
LED and the number of chassis alarms. The number of alarms is updated every second.
In the status mode, the second line displays:
Virtual Chassis port (VCP) status (supported only on EX4500 switches in a Virtual Chassis configuration
running Junos OS Release 11.1 or later. This option is not supported on standalone EX4500 switches.)
Status of the power supplies
Status of the fans in the fan tray and the chassis temperature
