3.5.3Connecting a 10BASE-F Segment to an EPIM-F1

NOTE

For proper operation, the EPIM-F1 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.

When connecting a fiber optic link segment with SMA 906 connectors to an EPIM-F1 with SMA ports, make sure each connector uses half alignment, NOT full alignment, sleeves. A full alignment sleeve damages the receive port. SMA 905 connectors do not need alignment sleeves.

Each fiber optic link consists of two strands of fiber optic cabling: the transmit (TX) and the receive (RX). The transmit strand from a module port connects to the receive port of a fiber optic Ethernet device at the other end of the segment. The receive strand of the applicable port on the module connects to the transmit port of the fiber optic Ethernet device.

Cabletron Systems recommends labeling fiber optic cables to indicate receive and transmit ends. Many cables are prelabeled, providing matching labels or tapes at both ends of each strand of cable.

Do not touch the ends of the fiber optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants. Contamination of cable ends causes problems in data transmissions. If necessary, clean contaminated cable ends using alcohol and a soft, clean, lint-free cloth.

1.Remove the protective plastic covers from the fiber optic ports on the applicable port on the module, and from the ends of the connectors on each fiber strand.

2.Attach one fiber to the receive port (RX) on the EPIM-F1. Insert the SMA connector into the port. Turn the connector clockwise until the connector will no longer turn easily. Do not overtighten the connector.
