STATUS + ALARM (Both LEDs)	Flashing Red	Secure Boot validation failure state. This case is only applicable immediately after power on.

MPA LEDs

The STATUS LED is located on the front left of the MPA, the attention (ATTN) is located on the front right of the MPA, and the Link LED for each port is located between the two rows of ports (each of these LEDs is a triangle pointing to the port above or below the LED).


LED	Color	Status
ATTN	Flashing blue	The operator has activated this LED to identify this MPA in the chassis.
ATTN	Off	This LED is not being used.
STATUS	Green	This MPA is operational.
	Amber	Either of the following conditions: The MPA has detected a slot ID parity error and will not power on or boot up. The MPA is not fully inserted.
	Flashing amber	The MPA is booting up or shutting down.
	Off	The MPA is powered-off and can now be safely removed.
Link (for each port)	Green	The port is active.
	Orange	The port is disabled by the operator or is not initializing.
	Flashing orange	The port is faulty and disabled.
	Off	The port is not active or the link is not connected.

Fan Tray LED

Fan tray modules are located on the back side of the chassis. Each fan tray module has a Status LED.
