CONNECTING TO THE NETWORKPage 4-5To connect an EPIM-T to a Twisted Pair Segment:1. Insert the RJ45 connector on the twisted pair segment into theRJ45 port on the EPIM. See Figure 4-3.2. Check that the EPIM’s LNK LED is on. If the LED is not on,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 RJ45 connector on the twisted pair segment hasthe proper pinouts.c. Check the cable for continuity.d. Check that the twisted pair connection meets dB loss and cablespecifications outlined in Chapter 2.e. Check that the crossover switch is in the correct position.If a link still has not been established, contact Cabletron SystemsTechnical Support.4.1.4 Connecting a Fiber Optic Link Segment to an EPIM-F1,EPIM-F2, or EPIM-F3When connecting a fiber optic link segment to an EPIM-F1, F2, or F3keep the following in mind:• If you are connecting a fiber optic link segment with SMA 906connectors to an EPIM-F1 with SMA ports, ensure that halfalignment sleeves are in place on each connector. A fullalignment sleeve will damage the receive port. SMA 905connectors do not need alignment sleeves.• If you are connecting a fiber optic link segment with STconnectors to an EPIM-F2 /F3 with ST ports, keep in mind thatST connectors attach to ST ports much like BNC connectorsattach to BNC ports. Insert the connector into the port with thealignment key on the connector inserted into the alignment sloton the port. The connector is then turned to lock it down.
