Chassis status LEDs

Table 3 describes the chassis status LEDs labeled SYS, ALM, and MST on an EX4100-H switch. The table also describes the LED color patterns and their status descriptions. You can view the colors of the LEDs remotely through the CLI by issuing the show chassis led operational mode command. Note that all LEDs can be lit simultaneously.

For information on the blink patterns of the CLD LED, which provide the cloud connection status of the switch, see Cloud Ready LED Blink Patterns, and to understand how the cloud connection works, see Cloud Connection Process.

Table 3: SYS, ALM, and MST Chassis Status LEDs on EX4100-H Switches
LED Label	Color	State and Description
SYS	Green	On steadily—Junos OS is loaded on the switch. Blinking—The switch is booting.
SYS	Unlit	The switch is powered off or is halted.
ALM	Red	A major hardware fault, such as a temperature alarm or a power failure alarm, occurred, and the switch is halted. A major alarm indicates a critical error condition that requires immediate attention (see Chassis Component Alarm Conditions on EX4100-H Switches).
	Amber	A minor alarm, such as a software or a hardware error, occurred. Power off the switch and then power it back on. Monitor the switch to see whether it is working properly. A minor alarm indicates a non-critical condition that requires monitoring or maintenance. A minor alarm that is left unchecked might cause interruption in service or performance degradation.
	Unlit	No alarm is in effect, or the switch is halted.
MST	Green	In a standalone switch: On steadily—The switch is functioning normally. Off—The switch is powered off or is halted.
MST	Green	In a Virtual Chassis configuration: On steadily—The switch is the primary one in the Virtual Chassis configuration. Blinking—The switch is the backup one in the Virtual Chassis configuration. Off—The switch is a linecard member in the Virtual Chassis configuration, or the switch is halted.

Note:

When issuing show system alarms, only the ALM LED of the master switch in a Virtual Chassis system glows to display the alarm state. Backup switch and linecard ALM LEDs will be unlit. However, when issuing show chassis alarms, ALM LED glows on all of the individual member switches, displaying their individual alarm states.

Note:

For Virtual Chassis deployments managed from the cloud, the CLD LED on individual Virtual Chassis members will reflect the state of the Master, except when a software download is in progress. When a software download is in progress, the CLD LED on a Virtual Chassis member will display the Junos OS upgrading LED pattern and color.

LEDs on the Management Port on EX4100-H Switches

The management port, labeled MGMT, on the front panel of EX4100-H switches has two LEDs that indicate the link activity and port status (see Figure 3 ).

LED Color	State and Description
Green	On steadily—The port and the link are active, but there is no link activity. Blinking—The port and the link are active, and there is link activity. Off—The port is not active.

EX4100-H switches have network port mode LEDs (labeled SPD, DX, EN, and POE) on the right side of the front panel (see Figure 13). These LEDs indicate the status of the network ports. Use the mode button on the right side of the front panel to toggle the status LEDs. You toggle the status LEDs to show the different port parameters for the network ports. The LED that is lit indicates the port parameter. Table 7 describes the status LEDs.
