EX2300 Chassis

Chassis Status LEDs in EX2300 Switches

The front panel of EX2300 switches except the EX2300-24MP and EX2300-48MP models has three chassis status LEDs labeled SYS, ALM, and MST. See Figure 1 and Figure 2.

Color

State and Description

SYS

Green

  • On steadily—Junos OS for EX Series switches has been loaded on the switch.

  • Blinking—The switch is booting.

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

ALM

Red

There is a major alarm.

Note:

When you connect power to the switch, the alarm LED (ALM) glows red. This behavior is normal. Plugging an active Ethernet cable into the management port (MGMT) on the switch completes the network link and turns off the ALM LED. (See Connect a Device to a Network for Out-of-Band Management.)

Connecting the switch to a dedicated management console instead of a network does not affect the ALM LED. The LED remains red until the switch is connected to a network.

Yellow

There is a minor alarm.

Note:

The ALM LED glows yellow if you commit a configuration to make it active on the switch without creating a rescue configuration to back it up. To save the most recently committed configuration as the rescue configuration, enter the operational mode command request system configuration rescue save.

Unlit

There is no alarm or the switch is halted.

MST

Green

In a standalone EX2300 switch:

  • On steadily—The switch is functioning normally as the primary.

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

In a Virtual Chassis configuration:

  • On steadily—The switch is functioning normally and is the primary in the Virtual Chassis configuration.

  • Blinking—The switch is functioning normally and is the backup in the Virtual Chassis configuration.

  • Off—The switch is a linecard member in the Virtual Chassis configuration or is halted.

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.

On EX2300 switches except the EX2300-24MP and EX2300-48MP models, you can view the colors of the two LEDs remotely through the CLI by issuing the operational mode command show chassis led.

The front panel of EX2300-24MP and EX2300-48MP models has three system LEDs labeled MGT, FAN, and PW. See Figure 3 and Figure 4.

State and Description

MGT

Green

  • On steadily—Junos OS for EX Series switches has been loaded on the switch.

  • Blinking—The switch is booting.

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

FAN

Amber—blinking

At least one of the fans has failed.

Green—on steadily

The fans are functioning normally.

Unlit

There is no alarm or the switch is powered off or halted.

PW

Green—on steadily

The power supply is functioning normally.

Amber—blinking

The supply of PoE power to RJ-45 network ports is disabled and the supply PoE/PoE+ power to devices connected to those ports is disabled.

Unlit

The switch is powered off .

Note:

PW LED stays solid green when switch is halted/powered-off using CLI commands request system power-off or request system halt.

Management Port LEDs in EX2300 Switches

The management port on an EX2300 switch has two LEDs that indicate link/activity and port status. The EX2300 switches except the EX2300-C switch and EX2300-24MP and EX2300-48MP models have the management port on the rear panel; the EX2300-C switches and EX2300-24MP and EX2300-48MP models have the management port on the front panel. See Figure 5, Figure 6, Figure 7, and Figure 8.
