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.

Chassis Status LEDs

Table 1 describes the chassis status LEDs in EX2300 switches except the EX2300-24MP and EX2300-48MP models, their colors and states, and the status they indicate.

Table 1: Chassis Status LEDs in EX2300 Switches Except the EX2300-24MP and EX2300-48MP Models
LED Label	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.

	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 or halted.

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.

RJ-45 Network Port LEDs and Uplink Port LEDs in EX2300 Switches

Each RJ-45 network port and uplink port on the front panel of EX2300 switches except the EX2300-24MP and EX2300-48MP switch models have two LEDs that indicate link/activity and port status. See Figure 9, Figure 10, and Figure 11.

Table 7 describes the Link/Activity LED on EX2300 switches except the EX2300-24MP and EX2300-48MP models.

Table 7: Link/Activity LED on the RJ-45 Network Ports and Uplink Ports in EX2300 Switches Except the EX2300-24MP and EX2300-48MP Models
LED	Color	State and Description
Link/Activity	Green	Blinking—The port and the link are active, and there is link activity; or the switch is transitioning to the EZSetup mode. On steadily—The port and the link are active, but there is no link activity; or the switch is reverting to the factory default configuration. Off—The port is not active.

Figure 12 shows the LEDs on EX2300 switches except the EX2300-24MP and EX2300-48MP models that indicate the status of one of the four port parameters—speed, duplex mode, administrative status, and Power over Ethernet (PoE) status. Use the Factory Reset/Mode button on the far right side of the front panel to toggle the Status LED to show the different port parameters for RJ-45 network ports. You can tell which port parameter is indicated by the Status LED by looking at which port status mode LED (SPD, DX, EN, and PoE) is lit. The LED labeled PoE is not available on switch models with RJ-45 network ports that do not provide PoE.

Table 8 describes the Status LED on the RJ-45 network ports in EX2300 switches except the EX2300-24MP and EX2300-48MP switch models.

Table 8: Status LED on the RJ-45 Network Ports in EX2300 Switches Except the EX2300-24MP and EX2300-48MP Models
Port Parameters	State and Description
Speed (SPD)	Indicates the speed. The speed indicators are: Unlit—10 Mbps Blinking—100 Mbps On steadily—1000 Mbps
Duplex mode (DX) Note: On EX2300-24T switches, only the ports labeled 0/0 through 0/15 support half-duplex. On EX2300-48T switches, only the ports labeled 0/0 through 0/15 and 0/24 through 0/39 support half-duplex.	Indicates the duplex mode. The status indicators are: Green—Port is set to full-duplex mode. Unlit—Port is set to half-duplex mode.
Administrative status (EN)	Indicates the administrative status. The status indicators are: Green—Port is administratively enabled. Unlit—Port is administratively disabled.
PoE status (PoE)	Indicates the PoE status. The status indicators are: On steadily—PoE is enabled on the port and a device is drawing power. Blinking—PoE is enabled on the port, but no power is drawn from the port. Unlit—PoE is not enabled on the port. Note: The PoE Status LED is available on the following EX2300 switch models: EX2300-C-12P EX2300-24P EX2300-48P

Starting in Junos OS Release 19.4R1, you can use the request chassis beacon command on EX2300 switches except the EX2300-24MP and EX2300-48MP switch models to identify the switch or a port on the switch. When you execute the command, the status LEDs on the RJ-45 network ports blink two times per second irrespective of the mode the ports are operating in (see How to Locate a Device or Port Using the Chassis Beacon).

The uplink ports operate in full-duplex mode and PoE is not applicable on uplink ports. The Status LED on uplink ports indicate the Speed (SPD) and Administrative status (EN). Table 9 describes the Status LED on the uplink ports in EX2300 switches except the EX2300-24MP and EX2300-48MP switch models.

Table 9: Status LED on the Uplink Ports in EX2300 Switches Except the EX2300-24MP and EX2300-48MP Models
LED	State and Description
Status LED	Indicates the speed and administrative status. The indicators are: On steadily—10 Gbps Blinking—1 Gbps Unlit—The port is administratively disabled or the link is down.

On EX2300 switches except the EX2300-24MP and EX2300-48MP models, you can tell which port parameter is indicated by the Status LED on RJ-45 network ports and uplink ports by issuing the operational mode command show chassis led.

Each RJ-45 network port and uplink port on the front panel of EX2300-24MP and EX2300-48MP switch models has one LED that indicates link/activity. See Figure 13, Figure 14, Figure 15, and Figure 16.

You can tell:

The speed and duplex mode at which a port is operating in by issuing the command show interfaces media.
The administrative status on each port by issuing the command show interfaces terse.
The PoE status on each port by issuing the command show poe interface.
