CONNECTING THE 5G106-06 TO THE NETWORK
The following sections describe how to make the fiber optic cable connections.
3.6.1
SC Fiber Connections to the Network
The fixed front panel ports 3 through 6 have an SC style connector used to connect to the Gigabit
Ethernet network. The GPIM-01, GPIM-08, and the GPIM-09 also have an SC style connector
used to connect to the Gigabit Ethernet network. Enterasys Networks offers fiber optic cables that
use SC style connectors which are keyed to ensure proper crossover of the transmit and receive
fibers (see
Figure 3-12
).
NOTE:
An odd number of crossovers (preferably one) must be maintained between like
devices so that the transmit port of one device is connected to the receive port of the
other device and vice versa.
