LCD Panel in an XRE200 External Routing Engine

The LCD panel on the XRE200 External Routing Engine shows two lines of text with a maximum of 16 characters in each line. The LCD panel displays a variety of information about the external Routing Engine and, if your external Routing Engine is running Junos OS Release 12.1 or later, provides menu options to perform basic operations such as initial configuration and switch reboot.

There are six buttons to the right of the LCD panel on the XRE200 External Routing Engine. You use four of the buttons—Up (↑), Down (↓), Enter (), and Cancel (X)—to navigate the LCD interface. The other two buttons—Left (←) and Right (→)—are not used for any purpose.

The LCD panel only provides information and menu options for XRE200 External Routing Engines in the primary role. You will see the text “BACKUP” in the LCD panel when the external Routing Engine is in the backup role. You cannot use the LCD menu buttons to navigate the menus for the backup external Routing Engine.

See Figure 3.

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 navigation buttons 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 any one of the four operational LCD panel buttons once. After turning on the backlight, you can toggle between the LCD menus by pressing the Up (↑) and Down (↓) buttons and select the menu options by pressing the Enter () button. You can return to the previous menu by pressing the Cancel (X) button.

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.

In the idle mode, line 2 of the Idle menu displays the Status LED modes of the network ports and the total number of alarms in the XRE200 External Routing Engine. The number of alarms is updated every second.

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

  • Virtual Chassis ports (VCPs)

  • Power supplies

  • Fans 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

    Note

    The EZSetup option is displayed in the LCD menu, but EZSetup is not supported for XRE200 External Routing Engines.

LCD Panel Menus

The LCD panel has three menus: Idle, Status, and Maintenance.

Toggle between the LCD menus by pressing the Up (↑) and Down (↓) buttons. Enter the Status or Maintenance menu by pressing the Enter () button.

Within the Status or Maintenance menu, toggle between the options by pressing the Up (↑) and Down (↓) buttons. Select the menus that can be selected by pressing the Enter () button. Exit the current menu and return to the previous menu by pressing the Cancel (X) button.

Table 1 describes the LCD panel menu options.

Menu

Description

Idle

Line 1 of the Idle menu displays the member ID and the hostname of the XRE200 External Routing Engine.

Line 2 of the Idle menu displays the Status LED modes of the network ports and the total number of alarms in the XRE200 External Routing Engine.

Sample output from the LCD panel in Idle mode:

09:RE xre200-1
    LED: NA ALARM 01

The Idle menu is not navigable. Press Up (↑) and Down (↓) to cycle to the Status and Maintenance menus from the Idle menu.

Status

The Status menu provides the following status information::

  • Virtual Chassis port (VCP) status—Displays the status of each VCP: Up, Down, or Disabled.

  • Power supply status—Displays the status of each power supply in the XRE200 External Routing Engine: OK, Failed, Absent.

  • Environment status—Displays the status of the following items:

    • Fans : OK, Failed, or Absent

    • Chassis temperature: OK, High, or Shutdown

  • Junos OS version status—Displays the Junos OS version running on the external Routing Engine:

  • EXIT STAT MENU?—Provides the option to leave the status menu. Press Enter () to exit the Status menu.

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

Maintenance

The Maintenance menu has the following options:

  • SYSTEM HALT?—Choose one of the following:

    • Press Enter () to halt the external Routing Engine.

      Note: An external Routing Engine switchover automatically occurs when the primary external Routing Engine is halted and a backup external Routing Engine is configured. If no backup external Routing Engine is configured, the EX8200 Virtual Chassis goes down when the primary external Routing Engine is halted.

    • Press Up (↑) and Down (↓) to go to another option in the Maintenance menu.

  • SYSTEM REBOOT?—Choose one of the following:

    • Press Enter () to reboot the external Routing Engine. Press Enter () again to confirm the reboot.

    • Press Up (↑) or Down (↓) to go to another option in the Maintenance menu.

  • LOAD RESCUE?—Choose one of the following:

    • Press Enter () to roll back the configuration to the rescue configuration. Press Enter () again to confirm the rollback.

    • Press Up (↑) or Down (↓) to go to another option in the Maintenance menu.

  • REQUEST VC PORT?—Choose one of the following:

    • Press Enter () to navigate to the VCP options. Choose one of the following:

      • SET VC PORT?—Set a link as a VCP.

      • DELETE VC PORT?—Disable a link that is currently configured as a VCP.

    • Press Up (↑) or Down (↓) to go to another option in the Maintenance menu.

  • FACTORY DEFAULT?—Choose one of the following:

    • Press Enter () to restore the external Routing Engine to the factory default configuration. Press Enter () again to confirm the restoration. The LCD panel flashes a success or failure message and returns to the Idle menu.

    • Press Up (↑) or Down (↓) to go to another option in the Maintenance menu.

  • ENTER EZSETUP?—This option is visible as an option in the LCD panel but it is not supported.

  • EXIT MAINT MENU?—Choose one of the following:

    • Press Enter () to exit the Maintenance menu.

    • Press Up (↑) or Down (↓) to go to another option in the Maintenance menu.

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).
