Connecting Fiber-Optic Cables from 7H4284-49 to the Network

This section provides the procedures to connect fiber-optic cables from the 100BASE-FX, MT-RJ
front panel ports of the 7H4284-49 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 a DFE module 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 DFE module 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 module, refer to
1. Remove the protective covers (not shown) from the MT-RJ front panel connector and from the
connectors on each end of the cable.
Note: Leave the protective covers in place when the connectors are not in use to
prevent contamination.
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 the ends of the fiber-optic strands become
contaminated, use a canned duster to blow the surfaces clean. A cleaning swab
saturated with optical-grade isopropyl alcohol may also be used to clean the ends.
Precaución: No toque los extremos de los cables de fibra óptica y evite su contacto con
el polvo, la suciedad o con cualquier otro contaminante. Si los extremos de los cables se
ensucian, es posible que la transmisión de datos se vea afectada. Si nota que los
extremos de los cables de fibra óptica se ensucian, utilice aire comprimido para
limpiarlos. También puede limpiarlos con un estropajo embebido en alcohol isopropílico.
2. Insert the MT-RJ cable connector into the MT-RJ front panel connector until it clicks into place.

Note: To remove the MT-RJ cable connector, press on its release tab and pull it out of
the Mini-GBIC.
