Table 2 describes the chassis status LEDs on an MX150, their colors and states, and the status they indicate. You can view the colors of the four LEDs remotely through the CLI by issuing the operational mode command show chassis craft-interface.

Table 2: Chassis Status LEDs in an MX150

LED Label

Color

State and Description

ALM (Alarm)

Unlit

There is no alarm or the device is halted.

Red

There is a major alarm.

Amber

There is a minor alarm.

SYS (System)

Green

  • On steadily—Junos OS has been loaded on the device.

  • Blinking—The device is booting.

  • Off—The device is powered off or is halted.

MST (Primary)

Green

  • On steadily—The device is functioning normally.

  • Off—The device is powered off or is halted.

PH

Unlit

This LED is not used. So, the status of this LED is off.

A major alarm (red) indicates a critical error condition that requires immediate action.

A minor alarm (amber) indicates a noncritical condition that requires monitoring or maintenance. A minor alarm left unchecked might cause interruption in service or performance degradation.

All three LEDs can be lit simultaneously.

Management Port LEDs on MX150

The management port on the front panel of an MX150 has two LEDs that indicate link activity and port status (see Figure 6).
