LCD Panel in an EX 8200 series Switch

The LCD panel on the top front of the EX 8200 series switch chassis shows two lines of text with a maximum of 16 characters in each line. The LCD panel displays a variety of information about the switch and provides menu options to perform basic operations such as initial configuration and switch reboot.

There are two navigation buttons—Menu and Enter—to the right of the LCD panel.

See Figure 1.

The LCD operates in four modes: boot, idle, status, and maintenance.

The LCD operates in boot mode during switch reboot. The LCD has three menus: Idle, Status, and Maintenance. In each of these menus, line one of the LCD panel displays the hostname of the switch.

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 Status LED modes and the total number of alarms in the system. The number of alarms is updated every two seconds.

To add a new user message to the Idle menu, use the set chassis display message message-string CLI command. The message replaces the LED modes and total number of alarms information in line two of the Idle menu for 300 seconds.

To display a user message permanently in line two of the Idle menu, use the set chassis display permanent message message-string CLI command.

You can delete the user message at any time using the clear chassis display message CLI command.

The status mode allows you to get status information for the following items:

  • Switch fabric in Switch Fabric and Routing Engine (SRE) modules in EX 8208 switches
  • Switch fabric in Switch Fabric (SF) module(s)
  • Power supplies
  • Fan tray(s) and chassis temperature
  • JUNOS software version installed

The maintenance mode allows you to cycle through options for configuring and troubleshooting the switch:

  • System halt
  • Reboot system
  • Load rescue configuration
  • Revert to factory configuration
  • EZSetup

You can toggle between the LCD menus by pressing the Menu button and navigate through the menu options by pressing the Enter button.

Table 1 describes the LCD menu options.
