Selecting a Crossover/Pass-Through Connection
Once a FiberLinX is installed, you can select a crossover workstation or
pass-through repeater/hub connection for the twisted pair data port.
FiberLinXî‚’s twisted pair data port has one RJ-45 connector for a single
shielded or unshielded twisted pair link segment and features a push-button
switch, located next to the port, for selecting the type of connection.
To select a pass-through connection on FiberLinX, simply press the push-
button IN. A crossover connection is selected when the push-button is OUT.
NOTE:If uncertain whether a crossover or pass-through connection is
needed, set the switch to the position that makes the TP data port link LED
glow.
LED Operation
FiberLinX features diagnostic LEDs for each port. The following illustration
shows the location of the LEDs on FiberLinX.

LEDs for the Fiber Data Port

LED functions for the fiber data port are as follows:
FDX Glows yellow when FDX is selected on port.
ACT Blinks green when data is detected on the
port.
LNK Glows green when a link is established.
FA Glows green when FiberAlert is enabled.

LEDs for the Twisted Pair Data Port

LED functions for the twisted pair data port are as follows:
LNK Glows green when a link is established.
FDX Glows yellow when FDX is selected on the
port.

LEDs for the Twisted Pair Management Port

LED functions for the twisted pair management port are as
follows:
LNK Glows green when a link is established.
FDX Glows yellow when FDX is selected on the
port.
FAR CPU
UP Glows yellow when far end is detected.
