Network LEDs
The onboard network solution has two network port LEDs. When the product is connected to a properly
working network through a network cable, the yellow LED indicates network activity, and the green LED
indicates the link status. A blinking yellow LED indicates network traffic. If the green LED is off, a link
has failed.
For link failures, check all of the network cable connections. In addition, you can try to manually
configure the network card link speed setting by using the product control-panel.
Change the Link Speed setting
1. From the Home screen on the product control panel, touch the Setup
button.
2. Scroll to, and then touch the Network Setup menu.
3. Scroll to, and then touch Link Speed item.
4. Touch the appropriate link speed.
Control panel LEDs
