Status LEDs

Top Previous Next

The DS202 has two pairs of status LEDs: one on the Ethernet connector itself (left side), and one on top of the Device. Both pairs are controlled by the same internal circuitry and exhibit exactly the same behavior.

Status LEDs display various status information depending on what firmware is running at the moment. Follow the links below to learn more about the behaviour of these LEDs under different conditions:

•	Status LED behavior in the monitor firmware

•	Status LED behavior in the application firmware

There are also two Ethernet Status LEDs- Green and Yellow- located on the Ethernet connector (right side):

•	Link/Data LED (green) is turned on when "live" Ethernet cable is plugged into the Module. The LED is temporarily switched off whenever an Ethernet packet is received.

•	100BaseT LED (yellow) is turned on when the DS202 links with the hub at 100Mb. The LED is off when the link is established at 10Mb.
