Troubleshooting
This section contains guidelines for troubleshooting the media converter in the event a problem
occurs.
If the MAIN LED is OFF, check the following:
• Check to be sure that the power cord for the main power supply is securely
connected to the power supply and the power outlet.
• Check that the power outlet has power by connecting another device to it.
• Check that the AC input power source is between 100 and 240VAC.
If an optional S.CON/PS redundant power supply is installed but the BCKP LED is OFF, check
the following:
• Check to be sure that the power cord for the S.CON/PS unit is securely connected
to the media converter and the power outlet.
• Check that the power outlet has power by connecting another device to it.
• Check that the AC input power source is between 100 and 240VAC.
If the F-LNK LED for a fiber optic port is OFF, check the following:
•
Check to be sure that an active F/O device (converter or other) is properly
connected and powered at the remote end..
•
Check to be sure that the fiber optic cable is properly connected to the fiber optic
port.
•
Verify that the maximum allowable loss budget on the fiber optic cable is within
acceptable limitis (see table 4).
If the T-LNK LED for a twisted pair port is OFF, check the following:
• Check to be sure the node connected to the port is powered ON.
• Check to be sure that the twisted pair cable is securely connected to both the port
on the media converter and the node.
• If the node connected to the port is a workstation, check to be sure that you used
a crossover cable. (a crossover cable is not necessary when connecting a hub or
switch to a twisted pair port on the media converter.)
