CONNECTING TO THE NETWORK
EMM-E6 User’s Guide 3-23
We recommend that you label the fiber optic cables to indicate
Receive and Transmit ends. Cabletron Systems prelabels its cable.
At one end of the cable, one fiber is labeled 1, and the other fiber is
labeled 2. This pattern repeats at the other end of the cable. If you
did not purchase your cable from Cabletron Systems, be sure to label
your cable in this manner.
To connect a fiber optic link segment to an EPIM-F1/F2 or an EPIM-F3:
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. On the EMM-E6, attach the fiber labeled 1 to the applicable receive
port, labeled RX (Figure 3-13).
3. On the EMM-E6, attach the fiber labeled 2 to the applicable transmit
port, labeled TX.
4. At the other end of the fiber optic cable, attach the fiber labeled 1 to
the transmit port of the device and the fiber labeled 2 to the receive
port.
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.
