LCD Panel in an EX8200 Switch

The LCD panel on the top front of the EX8200 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.

You can configure the second line of the LCD panel to display a custom message. If the LCD panel is configured to display a custom message, the Menu button and the Enter button are disabled. See Configuring the LCD Panel on EX Series Switches (CLI Procedure).

The LCD panel has a backlight. If the LCD panel is idle for 60 seconds, the backlight turns off. You can turn on the backlight by pressing the Menu or Enter button once. After turning on the backlight, you can toggle between the LCD menus by pressing the Menu button and navigate through the menu options by pressing the Enter button.

Note: The chassis viewer in the J-Web interface also displays the LCD panel. From the J-Web interface, you can view real-time status information in the LCD panel. See Dashboard for EX Series Switches.

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

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

LCD Panel Menus

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. Toggle between the LCD menus by pressing the Menu button. Navigate through the menu options by pressing the Enter button.

Table 1 describes the LCD menu options.

Maintenance

The Maintenance menu has the following options:

  • SYSTEM HALT?—Choose one of the following:
    • Press Enter to halt the master SRE module in an EX8208 switch or to halt the master RE module in an EX8216 switch. Press Enter again to confirm the halt.

      In a base configuration switch, the master SRE or RE module will be gracefully halted but not powered off. Press Enter on your management device or power cycle the switch to bring the switch back up.

      In a redundant configuration, the backup SRE or RE module takes over mastership when the master SRE or RE module is halted. To completely halt the switch, use the request system halt other-routing-engine CLI command to halt the backup SRE or RE module before halting the master SRE or RE module. Press Enter on your management device or power cycle the switch to bring the switch back up.

      See EX8208 Switch Configurations or EX8216 Switch Configurations for information on configuration types.

    • Press Menu to go to the next option in the Maintenance menu.
  • SYSTEM REBOOT?—Choose one of the following:
    • Press Enter to reboot the master SRE or RE module. Press Enter again to confirm the reboot.

    • Press Enter to exit the Maintenance menu.
    • Press Menu to return to the SYSTEM HALT option.

If you do not want users to use Maintenance menu options, disable the entire menu or individual menu options. See Configuring the LCD Panel on EX Series Switches (CLI Procedure).
