Troubleshooting
Follow the guidelines below to test and troubleshoot the installation in the
event a problem occurs.
If the POWER LED is OFF, do the following;
❑ Make sure that the power cord is securely connected to the wall outlet
and the power connector is securely connected to the back of the
switch.
❑ Verify that the power outlet has power by connecting another device
to it.
❑ Try using another power cord of the same type that came with your
switch.
If a LINK/ACT LED is OFF, do the following:
❑ Check 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.
❑ Verify that the end-node connected to the port and the switch are
operating at the same speed. Both must be operating at either 10
Mbps or 100 Mbps.
❑ Make sure that the twisted pair cable does not exceed 100 meters (328
feet) and that you are using a Category 3 or better cable for 10Base-T
operation or a Category 5 or better cable for 100Base-TX operation.
