Connecting to the Network
This section provides the procedure to connect fiber‐optic cables from the fixed front
panel MT‐RJ ports to the network or other devices. In addition this section will also cover
connections of any installed optional Mini‐GBICs to the network or other devices.

Connecting Fiber-Optic Cables from A2H124-24FX to the Network
This section provides the procedure to connect fiber‐optic cables from the 100BASE‐FX,
MT‐RJ front panel ports of the A2H124‐24FX 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 A2H124‐24FX 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.
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: 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.
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.
