Connecting Fiber-Optic Cables to Fixed MT-RJ Ports

This section provides the procedure to connect fiber‐optic cables from the 100BASE‐FX, MT‐RJ fixed front panel ports of the A2H254‐16 to the network or other devices. Each fiber‐optic link consists of two fiber‐optic strands within the cable: Transmit (TX) and Receive (RX).

The transmit strand from an A2H254‐16 port connects to the receive port of a fiber‐optic 100BASE‐FX Ethernet device at the other end of the segment. The receive strand of the applicable MT‐RJ port on the switch connects to the transmit port of the fiber‐optic 100BASE‐FX Ethernet device.

Note: An odd number of crossovers (preferably one) must be maintained between devices so that the transmit port is connected to the receive port of the other device and vice versa.

To connect a fiber‐optic cable segment to the switch, refer to Figure 3‐15 and proceed as follows:

1.Remove the protective covers (not shown) from the MT‐RJ front panel connector and from the connector on each end of the cable.

Note: Leave the protective covers in place when the connectors are not in use to prevent contamination.
