INSTALLATION3-73.5.1 Connecting the Network Port CablingYou attach unshielded twisted pair segments to the RJ-45 Network Portson the front panel of the MRXI. Since the MRXI utilizes polaritydetection and correction, the twisted pair connections are not sensitive tosignal polarity. The network will still function properly with the (+) and(–) lines within a pair reversed. Operating in this condition is notrecommended and if this condition is discovered, the segment should beremoved from the network and wired correctly by a technician.1. Connect twisted pair segments to the MRXI Network Port (see Figure3-7) by inserting the RJ-45 connector from each twisted pair segmentinto the desired RJ-45 port number on the MRXI.Figure 3-7 MRXI-24 Network Ports2. Check that the associated LNK LED for the port is lit. If the LED isnot lit, perform each of the following steps until it is:a. Check that the 10BASE-T device at the other end of the twistedpair segment is powered up.b. Verify that the RJ-45 connector on the twisted pair segment hasthe proper pin-outs as shown in Figure 3-8.24X 23X 22X 21X 20X 19X 18X 17X 16X 15X 14X 13X12X 11X 10X 9X 8X 7X 6X 5X 4X 3X 2X 1X EPIM 1EPIM 1
