3.5.6 Connecting an AUI Cable to an EPIM-A

To connect an EPIM-A to an external network segment, via an AUI Cable:

1. Attach an external transceiver to the network segment that will be

connected to the AUI port. Refer to the applicable transceiver manual.

2. Attach an AUI cable, no longer than 50 meters in length, to the

transceiver connected to the network in step 1.

3. Connect the AUI cable to the AUI port located on the EPIM-A. See

Figure 3-15.

4. Lock the AUI connector into place using the slide latch on the

connector.

Figure 3-15 The EPIM-A

CAUTION: Ensure that the external transceiver to which the MRXI will be

connected does not have the signal quality error (SQE or “heartbeat”) test

function enabled. The MRXI will not operate if the transceiver has the

SQE test function enabled, and the network will be unusable. Refer to the

applicable transceiver manual.

5. Check that the PWR LED on the EPIM-A is lit. If the PWR LED is

not lit, contact Cabletron Systems Technical Support.

6. If the PWR LED is lit with the AUI cable disconnected, continue with

the following checks:

a. Check the AUI connections for proper pin-outs. The pin-outs for

the transceiver connection are listed in Chapter 2, Installation

Requirements/Speciﬁcations.

b. Check the cable for continuity.

c. Reconnect the AUI cable to the MRXI and the device.

If the LED is still not lit after reconnecting the segment, contact Cabletron

Systems Technical Support.
