Connecting the Network Port Cabling
You attach unshielded twisted pair segments to the RJ-45 Network Ports
on the front panel of the MRXI. Since the MRXI utilizes polarity
detection and correction, the twisted pair connections are not sensitive to
signal polarity. The network will still function properly with the (+) and
(–) lines within a pair reversed. Operating in this condition is not
recommended and if this condition is discovered, the segment should be
removed from the network and wired correctly by a technician.

1. Connect twisted pair segments to the MRXI Network Port (see Figure
3-7) by inserting the RJ-45 connector from each twisted pair segment
into the desired RJ-45 port number on the MRXI.

2. Check that the associated LNK LED for the port is lit. If the LED is
not lit, perform each of the following steps until it is:

Check that the 10BASE-T device at the other end of the twisted
pair segment is powered up.

b. Verify that the RJ-45 connector on the twisted pair segment has
the proper pin-outs as shown in Figure 3-8.
