LCD Panel Modes
The LCD panel operates in four modes: boot, idle, status, and maintenance.
The first line of text on the LCD panel displays the slot number, the role of the switch, and hostname in
all the modes.
For a standalone EX4300 switch, by default the slot number is 00, and the role is RE.
In an EX4300 switch that is a member of a Virtual Chassis, the first line of the LCD panel always
displays:
• The slot number (the member ID of the Virtual Chassis member)
• Role of the switch in the Virtual Chassis (RE for primary, BK for backup, and LC for line card member)
• Hostname
The LCD panel operates in boot mode during switch reboot. In the boot mode, the second line of the
LCD panel 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 (IDLE)
menu.
In 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 status mode, the second line displays:
• Status of the Virtual Chassis port (VCP)
• Status of the power supplies
• Status of the fan modules and the chassis temperature
• Version of Junos OS for EX Series switches loaded on the switch
In maintenance mode, the second line displays one of the following options, which you can use to
configure and troubleshoot the switch:
• System halt
