Chassis Status LEDs on MX150

The front panel of an MX150 has chassis status LEDs (labeled ALM, SYS, MST and PH), next to the MGMT port (see Figure 3).

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.

Each network port and uplink port on the front panel of an MX150 has two LEDs that indicate link activity and port status (see Figure 4).

Table 3 describes the link activity of the LED.

Color

State and Description

Link activity

Green

  • Blinking—The port and the link are active, and there is link activity.

  • On steadily—The port and the link are active, but there is no link activity.

  • Off—The port is not active.

Figure 5 shows the LEDs that indicate the status of one of the three port parameters—speed, duplex mode, and administrative status. Use the Mode button on the far right side of the front panel to display the status LED for the different port parameters. You can tell which port parameter (speed, duplex mode, or administrative status) is indicated by the ST LED by looking at which port parameter LED (SPD, DX, or EN) is lit.

Table 4 describes the port parameters LED.

Table 4: Port Parameter LED on the Network Ports and Uplink Ports in MX150

Port Parameter LED

State and Description

SPD (speed)

Indicates the speed. The speed indicators for network ports and uplink ports are:

  • One blink per second—10 Mbps

  • Two blinks per second—100 Mbps

  • Three blinks per second—1000 Mbps

DX (duplex mode)

Indicates the duplex mode. The status indicators are:

  • On steadily—Port is set to full-duplex mode.

  • Off—Port is set to half-duplex mode.

EN (administrative status)

Indicates the administrative status. The status indicators are:

  • On steadily—Port is administratively enabled.

  • Off—Port is administratively disabled.

You can tell which port parameter is indicated by the Status LED on network ports by issuing the operational mode command show chassis craft-interface.

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).
