CONNECTING TO THE NETWORK

To connect an EPIM-T to a Twisted Pair Segment:

1.Insert the RJ45 connector on the twisted pair segment into the RJ45 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 twisted pair segment is powered up.

b.Verify that the RJ45 connector on the twisted pair segment has the proper pinouts.

c.Check the cable for continuity.

d.Check that the twisted pair connection meets dB loss and cable specifications 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 Systems Technical Support.

4.1.4Connecting a Fiber Optic Link Segment to an EPIM-F1, EPIM-F2, or EPIM-F3

When connecting a fiber optic link segment to an EPIM-F1, F2, or F3 keep the following in mind:

If you are connecting a fiber optic link segment with SMA 906 connectors to an EPIM-F1 with SMA ports, ensure that half alignment sleeves are in place on each connector. A full alignment sleeve will damage the receive port. SMA 905 connectors do not need alignment sleeves.

If you are connecting a fiber optic link segment with ST connectors to an EPIM-F2 /F3 with ST ports, keep in mind that ST connectors attach to ST ports much like BNC connectors attach to BNC ports. Insert the connector into the port with the alignment key on the connector inserted into the alignment slot on the port. The connector is then turned to lock it down.
