Making Connections
33
The Fast Ethernet module uses a MDI-X connector (not a straight MDI) and,
therefore, a crossover cable must be used when connecting the module to
another module (and under most other circumstances). See Appendix A for
pinout information.
The Fast Ethernet module includes the following LED indicators:
•
Power/Tx
his LED is lit when the hub is on and blinks when packets
are being transmitted by the module.
•
Link/Rx
his LED is lit when the port is properly connected to a pow-
ered-on device and blinks when packets are being received by the
module.
•
Collision
his LED blinks when there are packet collisions on the mod-
ule line.
•
FDX
his LED is lit when the port is set for Full Duplex transmit and
receive. When the LED is off, the port is in Half Duplex mode.
NOTE:
Because the DFE-260TX module
port is an
NWay UTP port, once the hub is powered on,
it will automatically detect the duplex and
speed modes of any device connected to it.
The DIP switch may then be set to force the
duplex mode into a particular state. After the
DIP switch is set, the DFE-260TX will only op-
