connected to the DC power connector on the switch.
Verify that the power outlet has power by connecting another device
to it.
Try connecting the unit to another power source.

blinking. If an LED is OFF, do the following:
Verify that the end node connected to the port is powered ON and is
operating properly.
Check that the twisted pair cable is securely connected to the port on
the switch and to the port on the end node.
Make sure that the twisted pair cable does not exceed 100 meters (328
feet).
Verify that you are using the appropriate category of twisted pair
cable: Category 3 or better for 10 Mbps operation and Category 5 for
100 Mbps operation.
Check that the LINK/ACT LED for the fiber optic port is steady green or
blinking. If the LED is OFF, do the following:
