Chassis Status LEDs on NFX250 Devices

The front panel of an NFX250 device has chassis status LEDs (labeled ALM, SYS, MST and PH) , next to the MGMT port (see Figure 3).

Table 1 describes the chassis status LEDs in NFX250 Device, 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 led.

Table 1: Chassis Status LEDs in an NFX250 Device

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 (Master)

Green

  • On steadily—The device is functioning normally.

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

PH

Unlit

There is no Network Service Activator transaction.

Green

  • On steadily—Network Service Activator transaction is successfully completed. That is, the Network Service Orchestrator in NFX250 contacted the Network Service Activator and provisioned the software image successfully.

  • Blinking—Network Service Activator transaction is underway.

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

Amber

  • On steadily—Network Service Activator transaction is terminated unsuccessfully.

  • Blinking—Network Service Activator transaction is waiting for user input.

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 four LEDs can be lit simultaneously.

Each network port and uplink port on the front panel of an NFX250 has two LEDs that indicate link activity and port status (see Figure 4).

Table 2 describes the Link/Activity 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 toggle the Status LED to show the different port parameters. You can tell which port parameter (speed, duplex mode, or administrative status) is indicated by the Status LED by looking at which port status mode LED (SPD, DX, or EN) is lit.

Port Parameters

State and Description

Speed

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

  • One blink per second—10 Mbps

  • Two blinks per second—100 Mbps

  • Three blinks per second—1000 Mbps

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.

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 led.

Management Port LEDs on NFX250 Devices

The management port on the front panel of an NFX250 device has two LEDs that indicate link activity and port status (see Figure 6).
