LEDs

The LEDs indicate the following information:

1Gbe connectors with SFP transceivers

Default ports on SN-S-Series-220, SN- S-Series-320, SN-M-Series-520, SN910 and SNi40 models

A green LED will light up when the link is established and blink depending on the volume of traffic. For SN-M-Series-520 models, the position of LEDs is shown in the diagram on the right.

Extension modules for SN710, SN910, SN-M-Series-520, SN-M-Series-720, SN-M-Series-920, SN1100, SN2100, SN3100 SN-L-Series-2200, SN-L-Series-3200, SN-XL-Series-5200 and SN-XL-Series-6200 models

A green LED will light up when the link is established and blink depending on the volume of traffic.

Default ports on SNi20* models

Both lower LEDs correspond to port 5 and both upper LEDs correspond to port 6. The position of LEDs is shown in the diagram on the right.

Name	Color	Status	Status
Upper LED SPEED	Yellow	On	Media speed negotiated at 1Gbps.
Lower LED ACT/LINK	Green	On	Link established between the Ethernet port and the connected appliance.
		Off	Ethernet port switched off or link not established with the connected appliance.
		Blinking	The Ethernet port is sending or receiving data. The blinking speed varies according to the volume of traffic.

* may vary by license.
