Installation Tips

Note:

These tips are additional to the Installation

Instructions that can be found on the back of 
the unit.

▼ 

The RJ45 ports on the LFX2-MA are
autosensing for speed and for half/full
duplex operation. When the unit is powered
on, verify the correct modes of operation by
examining the LEDs for that port. No further
configuration is necessary. If the correct
mode of operation does not appear in the
LED display, check the cable and connecting
equipment. If changes are made, power 
the unit off and then on again to reset.

▼ 

If the optional MII or AUI port is selected for
either one of the ports, then the RJ45 interface
on that port is rendered inoperative.

▼ 

If the Link/Duplex LED for a port is not lit,
please check the cable being used. The
port will only be operational if the LED is
green (Good Link/Half Duplex) or yellow
(Good Link/Full Duplex).
