Port LEDs

On the SSA, you can view the receive and transmit activity on the RX and TX LEDs for the RJ45, SFP, and SFP+ ports. See RJ45 Port LEDs below and SFP and SFP+ Port LEDS.

RJ45 Port LEDs

SFP and SFP+ Port LEDS

Note

SFP and SFP+ Port LEDS shows SFP ports. The LEDs are the same for both SFP and SFP+ ports.

Port LEDs describes the LED indications for the RX and TX LEDs for the RJ45, SFP, and SFP+ ports and provides recommended actions.

Port LEDs

LED	Color	State	Recommended Action
RX (Receive)	None	No link. No activity. Port enabled or disabled.	None
	Green	Solid: Link present, port enabled, no traffic is being received by the interface.	None
	Yellow	Blinking: Link present, port enabled, traffic is being received by the interface.	None
TX (Transmit)	None	Port enabled, but no activity.	If you know the port should be active and is not, contact us.
	Green	Blinking: Indicates data transmission activity. Flashing frequency indicates the data rate.	None
	Yellow	Solid: Fault or error (collision).	None, unless activity is high – in which case, check for network configuration problems or a defective device.

RJ45 Port LEDs—PoE Mode describes the LED indications for the RX and TX LEDs when the RJ45 ports are in PoE mode. You can switch the RJ45 ports between PoE mode and RX/TX mode by pressing the red POE button in the upper right corner of the SSA. The POE LED, described in System LEDs, indicates whether the RJ45 port LEDs are in PoE mode or RX/TX mode.

RJ45 Port LEDs—PoE Mode

RX LED Color	TX LED Color	State
Green	None	There is a connection to the powered device (PD), and there is 48 VDC at the RJ45 connector.
None	Yellow	Port is off due to overload: attached PD exceeded maximum load.
Yellow	None	Port is off due to PoE power management.
None	None	Port is off for another reason.
