CONNECTING THE RMIM/EPIM TO THE NETWORK
Installation Guide 3-17
To connect a fiber optic link segment to a FORMIM, EPIM-F1, EPIM-F2 or
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. Attach the fiber labeled 1 (Fig. 3-11) to the applicable receive port, labeled
RX, on the module.
3. Attach the fiber labeled 2 to the applicable transmit port, labeled TX, on the
module.
4. At the other end of the fiber optic cable, attach the fiber labeled 1 to the
transmit port of the device.
5. Attach the fiber labeled 2 to the receive port.
6. Check that the Link LED on the applicable port on the module is lit. If the
LED is unlit, perform the following steps until it is:
a. Check that the power is turned on for the device at the other end of the
link.
b. Verify that the fiber strands are properly “crossed over” between the
applicable port on the module and the fiber optic device at the other end
of the fiber optic link segment.
c. Verify that the fiber connection meets the dB loss specifications
outlined in Fiber Optic Network Requirements.
If a link still isn’t established, contact Cabletron Systems Technical Support.
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 can cause problems in data
transmissions. If the ends become contaminated, clean them with
alcohol using a soft, clean, lint free cloth.
