Chassis and Module LEDs

---

This appendix lists the Cisco Nexus 7000 Series system LEDs and describes the conditions they indicate for the chassis and each type of module installed in the chassis.

Table C-1 describes the system LEDs that are located on the chassis.

Table C-1 System LEDs

LED	Color	Condition
PSU	Green	Power supply units are all operational.
	Amber	One of the following problems has occurred: •Any power supply unit LED is red. •Any power supply unit is down.
FAN	Green	Fan tray modules are all operational.
	Amber	At least one fan tray module has a red STATUS LED.
SUP	Green	Supervisor modules are all operational.
	Amber	At least one supervisor module has a red STATUS LED.
FAB	Green	Fabric modules are all operational.
	Amber	At least one fabric module has a red STATUS LED.
IOM	Green	I/O modules are all operational.
	Amber	At least one I/O module has a red STATUS LED.

Table C-2 describes the supervisor module LEDs.

Table C-2 Supervisor Module LEDs  

LED	Status	Description
STATUS	Green	All diagnostics pass. The module is operational (normal initialization sequence).
	Red	The module has detected a slot ID parity error and will not power on or boot up. or The module is not fully inserted and does not have a reliable connection to the midplane. or The diagnostic test has failed.
	Blinking red	The inlet air temperature of the system has exceeded the safe operating temperature limits of the card (a major environmental warning). The card has been shut down to prevent permanent damage. The system will be shut down after two minutes if this condition is not cleared. or The module is resetting, and both ejector levers are out.
	Off	The module is not receiving power.
ID	Blinking blue	The operator has activated this LED to identify this module in the chassis.
	Off	This module is not being identified.
SYSTEM	Green	All chassis environmental monitors are reporting okay.
	Amber	At least one power supply has failed or the power supply fan has failed.
	Red	The temperature of the supervisor engine major threshold has been exceeded.
	Off	The slot has detected a slot ID parity error.
ACTIVE	Green	The supervisor module is operational and active.
	Amber	The supervisor module is in standby mode.
PWR MGMT	Green	Sufficient power is available for all of the installed modules.
	Amber	Insufficient power is available for all of the installed modules.
MGMT ETH	Green	The management port is operational.
	Amber	The management port link has been disabled through the software.
	Flashing Amber	The management port link is bad and has been disabled due to a hardware failure.
	Off	The module has not detected a signal.
LINK	Green	The module has detected a link.
	Off	The module does not detect a link.
ACT	Flashing green	The module is transmitting or receiving.
	Off	The module is not transmitting or receiving.
ACT LOG FLASH	Green	The log flash CompactFlash is being accessed. Do not remove the Compact Flash until the LED is off.
	Off	The expansion flash CompactFlash is not being accessed. You can remove the CompactFlash while this LED is off.
ACT EXPANSION FLASH	Green	The expansion flash CompactFlash is being accessed. Do not remove the Compact Flash until the LED is off.
	Off	The log flash CompactFlash is not being accessed. You can remove the CompactFlash while this LED is off.
CMP MGMT ETH	Green	The management port is operational.
	Amber	The management port link has been disabled through the software.
	Flashing amber	The management port link is bad and has been disabled due to a hardware failure.
	Off	The module does not detect a signal.
CMP STATUS	Green	All diagnostics pass. The CMP is operational (normal initialization sequence).
	Amber	Sufficient power is not available for all modules.
	Flashing amber	The diagnostic test has failed. or The CMP is not operational because a fault has occurred during the initialization sequence.
	Red	The module has detected a slot ID parity error.
	Off	The CMP is not receiving power.
LINK	Green	The module has detected a link.
	Off	The module has not detected a link.
ACT	Flashing green	The module is transmitting or receiving.
	Off	The module is not transmitting or receiving.

Table C-3 describes the I/O module LEDs.

Table C-3 I/O Module LEDs 

LED	Status	Description
ID	Blinking blue	The operator has activated this LED to identify this module in the chassis.
	Off	This module is not being identified.
Status	Green	All diagnostics pass. The module is operational (normal initialization sequence).
	Red	The module has detected a slot ID parity error and will not power on or boot up. or The module is not fully inserted, and it is not making a reliable connection with the supervisor. or The module has failed diagnostic tests and has powered down.
	Blinking red	The switch has just been powered on, and the module is resetting. or The module is resetting and both ejector levers are out. or The module has been inserted during the initialization process. or The module could not power up because of insufficient power. or An overtemperature condition has occurred. A major temperature threshold has been exceeded during environmental monitoring.
	Off	The module is not receiving power.
Link (for each port)	Green	The port is active (the link is connected and active).
	Orange	The port is disabled by the operator or is not initializing.
	Blinking orange	The port is faulty and disabled.
	Off	The port is not active or the link is not connected.

Table C-4 describes the fabric module LEDs.

Table C-4 Fabric Module LEDs 

LED	Status	Description
Status	Green	All diagnostics pass. The module is operational (normal initialization sequence).
	Red	The diagnostic test has failed. The module is not operational because a fault has occurred during the initialization sequence. or The inlet air temperature of the system has exceeded the safe operating temperature limits of the card (a major environmental warning). The card has been shut down to prevent permanent damage.
