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.
Table 1: LCD Panel Menu Options for the XRE200 External Routing Engine
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::
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:
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). |
Chassis LEDs on an XRE200 External Routing Engine
The XRE200 External Routing Engine has three chassis LEDs on the bottom left side of the front panel.
Table 2 describes the chassis LEDs on an XRE200 External Routing Engine, their colors and states, and the status they indicate. You can also view the colors of the three LEDs remotely through the CLI by issuing the operational mode command show chassis led.
Table 2: Chassis LEDs in an XRE200 External Routing Engine
LED Label (Description) | Color | State and Description |
---|---|---|
Power | Unlit | External Routing Engine is powered off. |
Green (on) | External Routing Engine is powered on. | |
Hard Disk Drive | Unlit | Data is not being read from or written to the hard disk drive. |
Yellow (blinking) | Data is being read from or written to the hard disk drive. | |
Hardware | Unlit | External Routing Engine hardware has no major (red) alarm conditions. |
Red (on) | External Routing Engine hardware is hotter than the maximum high temperature threshold. | |
Red (fast blinking) | At least one fan has failed. | |
Red (slow blinking) | A power supply is not supplying power to the external Routing Engine. |
A major alarm (red) indicates a critical error condition that requires immediate action.
A minor alarm (yellow) indicates a noncritical condition that requires monitoring or maintenance. A minor alarm that is left unchecked might cause interruption in service or performance degradation.
All three LEDs can be lit simultaneously.
Management Port LEDs on an XRE200 External Routing Engine
The management port (labeled MGMT) on the XRE200 External Routing Engine has two LEDs that indicate link/activity and port status (see Figure 4). The management port is set to full duplex and the speed is set to 100 Mbps.

Table 3 describes the Link/Activity LED.
