Chapter 3: Installation

3. If the transceiver PWR LED is OFF with the AUI cable connected, 

perform the following steps:

a.

Check the AUI connections for proper pinouts.

b. Check the cable for continuity.

c.

Reconnect the AUI cable to the EMM-E6 and the device.

If the transceiver PWR LED remains OFF, contact Cabletron Systems 
Technical Support.

To connect a thin coaxial cable segment to an EPIM-C perform the 
following steps:

Before attaching a male BNC connector to a female BNC barrel 
connector or terminator, look into the end of the connector to verify that 
the gold contact pin is present and centered. Any bent or broken pins may 
not connect properly and should be replaced.

1. Set the Internal Termination (TERM) switch, located to the right of the 

port and labeled TERM, to one of the following positions:

a.

The ON position ( ) to internally terminate the thin coaxial cable 
segment at the port. Thin coaxial cable segments may be directly 
connected to the port.

b. The OFF position ( ) to not internally terminate the thin coaxial 

cable segment at the port. Segments may only be connected 
through T-connectors which are connected to properly terminated 
segments on both ends.

For proper operation, the EPIM-C module to be configured for 
use in the EMM-E6 module must be of EPIM board revision 05 
or greater. Board revision numbers are found following the part 
number printed on the Printed Circuit Board of the EPIM.
