2 — em0–RJ-45 (10/100/1000 BASE-T) management Ethernet port (C0)	5 — em1–SFP management Ethernet port (C1) cage (socket for either 10/100/1000 BASE-T RJ-45 SFP or 1-GbE fiber SFP)
3 — RJ-45 console port (CON)

Table 1 describes the chassis status LEDs on a QFX5110, their colors and states, and the status they indicate. You can view the colors of the three LEDs remotely through the CLI by issuing the operational mode command show chassis lcd.

Name	Color	State	Description
ALM–Alarm or beacon	Unlit	Off	The switch is halted or there is no alarm.
	Red	On steadily	A major hardware fault has occurred, such as a temperature alarm or power failure, and the switch has halted. Power off the QFX5110 by setting the AC power source outlet to the off (O) position, or unplugging the AC power cords. Correct any voltage or site temperature issues, and allow the switch to cool down. Power on the QFX5110 and monitor the power supply and fan LEDs to help determine where the error is occurring.
	Amber	On steadily	A minor, non-critical alarm has occurred, such as a software error. Power off the QFX5110 by setting the AC power source outlet to the off (O) position, or unplugging the AC power cords. Power on the QFX5110 and monitor the status LEDs to ensure that Junos OS boots properly.
SYS–System	Unlit	Off	The switch is powered off or halted.
	Green	On steadily	Junos OS for QFX Series is loaded on the switch.
	Green	Blinking	The switch is participating as: A member in a QFX Virtual Chassis A leaf device in a Virtual Chassis Fabric (VCF) A spine device in a VCF A Routing Engine Primary in a VCF A Routing Engine Backup in a VCF
MST–Primary in a QFX Virtual Chassis or Routing Engine Primary in a VCF	Unlit	Off	The switch is a line card member in a QFX Virtual Chassis.
	Green	On steadily	The switch is one of the following: A standalone switch In the primary role in a QFX Virtual Chassis Is the routing engine primary in a VCF
	Green	Blinking	The switch is the backup primary in a QFX Virtual Chassis or the backup routing engine in a VCF.
ID–Identification	Unlit	Off	The beacon feature is not enabled on the switch. This feature is enabled using the `request chassis beacon` command.
