Cabletron Systems EMM-E6 Ethernet manual Connecting to the Network

CONNECTING TO THE NETWORK

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.

CAUTION

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.

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.
