Verify that the LNK/ACTY LED for each twisted pair port is either on or
blinking. If an LED is off, do the following:
G Verify that the end node connected to the port is powered ON and is
operating properly.
G Check that the twisted pair cable is securely connected to the port on
the switch and to the port on the end node.
G Make sure that the twisted pair cable does not exceed 100 meters (328
feet).
Check that the LNK/ACTY LED for the fiber optic port is steady green or
blinking. If the LED is off, do the following:
G Verify that the end node connected to the port is powered ON and is
operating properly.
G Check that the fiber optic cable is securely connected to the port on the
switch and to the port on the end node.
G Make sure that the cable connected to the fiber optic receiver port on
the switch is connected to the transmitter port on the remote end node
and that the fiber optic transmitter port on the switch is connected to
the receiver port on the end node.
G Test the attenuation on the fiber cable to ensure that it does not
exceed acceptable values.
G Verify that you are using the appropriate type of fiber optic cabling
and that you have not exceeded the allowable maximum distance. For
information, refer to the “Installing the Twisted Pair and Fiber Optic
Cabling” on page 19
G Make sure that the 100FX DUPLEX switch is set correctly. The switch
should be set to match the duplex mode of the end node connected to
the fiber optic port.
G Check that the operating specifications (e.g., wavelength and
maximum operating distance) of the fiber optic port on the end node
are compatible with the operating specifications of the fiber optic port
on the Ethernet switch.
Note
See “Technical Specifications” on page 24 for the operating
specifications of the fiber optic port on the switch.
