INSTALLATIONPage 3-93.5 CONNECTING THE HUB TO THE ETHERNET NETWORKThe procedure for connecting Ethernet segments to the unit will varydepending on the media and ports being connected. Refer to thefollowing list and and perform the procedure described in thesubsections that apply to your HUB:• Network Port (MRX/MRXI) 3.5.1• Network Port (MRX-2/MRXI-2) 3.5.2• SPIM-T 3.5.3• SPIM-T1 3.5.4• SPIM-F1 3.5.5• SPIM-F2 3.5.6• SPIM-C 3.5.7• SPIM-A 3.5.83.5.1 Connecting the Network Port Cabling (MRX/MRXI)The MRX and MRXI Network Port cabling uses a 50-pin Champconnector to attach up to twelve unshielded twisted pair segments tothe HUB. The Network feeder cable typically connects to a punch-down block using a 50-pin Champ connector, but in some cases theconnection could require wiring the block for the individual twistedpairs. The Appendix provides a guide to wiring the punch-downblock when a 50-pin Champ connector is not being used.3.5.2 Connecting the Network Port Cabling (MRX-2/MRXI-2)The MRX-2 and MRXI-2 Network Port consists of 12- RJ-45connectors, used to attach up to twelve unshielded twisted pairsegments to the HUB. The X associated with each port numberindicates that the port is internally crossed over.NOTE: The X indicating crossover is omitted on some units.However, the RJ-45 Network ports are internally crossed over.1. Connect twisted pair segments (see Figure 3-7) to the HUBNetwork Port by inserting the RJ-45 connector from each twistedpair segment into the desired RJ-45 port number on the HUB.
