Label the fiber optic cable to indicate which fiber is receive and which 
is transmit. Cabletron Systems fiber optic cable is labeled so that one 
fiber is labeled 1, and the other fiber is labeled 2 at both ends of the 
cable. If the cable was not purchased from Cabletron Systems, label 
the cable as described above.
Use the following steps to connect a fiber optic link segment to the SEHI:
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 the fiber labeled 1 to the applicable RX port, on the SEHI. See

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 the ends causes problems in data 
transmissions. If the ends become contaminated, clean them 
with alcohol using a soft, clean, lint-free cloth.
