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 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.
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.
