Check the PWR LED on the front of the switch. If the LED is OFF,
indicating that the unit is not receiving power, do the following:
Verify that the power cord is securely connected to the power source
and to the connector on the back panel of the switch.
Verify that the AC power outlet or power adapter has power by
connecting another device to it.
Try connecting the power adapter to another power source.
Verify that the voltage from the power source is within the required
levels for your region.
Verify that the L/A LED for each port is green. If an L/A LED is OFF, do the
following:
Verify that the end-node connected to the port is powered ON and is
operating properly.
Verify that the twisted pair cable is securely connected to the port on
the switch and to the port on the end-node.
Ensure 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.
