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 master, 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.

Chassis configuration running Junos OS Release 11.1 or later. This option is not supported
on standalone EX4500 switches.)
