Cabletron Systems 42T To connect a fiber optic link segment to the TPIM-F2 /-F3, The TPIM-F2/-F3

INSTALLATION

•The physical communication link consists of two strands of fiber optic cabling. The Transmit strand (TX) at one end connects to the Receive (RX) port at the other end and vice versa.

•Cabletron Systems labels its fiber optic cable to indicate which fiber is Receive and which is Transmit: one fiber is labeled 1, and the other fiber is labeled 2. If using a non-Cabletron cable, labeling in the above manner is recommended.

CAUTION: Do not touch the ends of the fiber optic strands. Dust, dirt, and other contaminants on the ends of the strands create data transmissions problems. If the ends become dirty, clean them with alcohol using a soft, clean, lint free cloth.

To connect a fiber optic link segment to the TPIM-F2 /-F3:

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

2.As shown in Figure 3-17, attach the fiber labeled 1 to the module’s receive port (labeled RX) and attach the fiber labeled 2 to the module’s transmit port (labeled TX).

3.At the other end of the fiber optic cable, attach the fiber labeled 1 to the transmit port of the device and attach the fiber labeled 2 to the receive port.

4.Check that the LNK LED on the TPIM lights green. If the LED does not light, perform each of the following steps:
