CONNECTING TO THE NETWORK
Page 4-5
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

4.1.4 Connecting 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.
