CONNECTING TO THE NETWORK
This section provides the procedures for connecting fiber optic cable from the network or other
devices to the module. For details on how to obtain more information, refer to the “

.
The front panel ports of the module are 10BASE-FL MT-RJ ports.
Each fiber optic link consists of two fiber optic strands within the cable: the transmit (TX) and the
receive (RX). The transmit strand from a module port connects to the receive port of a fiber optic
Fast Ethernet device at the other end of the segment. The receive strand of the applicable port on
the module connects to the transmit port of the fiber optic Fast Ethernet device.
Enterasys Networks recommends labeling fiber optic cables to indicate receive and transmit ends.
Many cables are prelabeled, providing matching labels or tapes at both ends of each strand of
cable.
The following instructions detail the process used to connect an MT-RJ connector to a module
port.
1.
Remove the protective covers from the fiber optic ports on the applicable port on the device, and
from the connectors on each end of the cable.
2.
Insert the MT-RJ fiber optic cable connector on the cable into the MT-RJ connector on the
device until it clicks into place. See
Figure 3-3
.
NOTE:
If the module is being installed in a network using SmartTrunking, there are
rules concerning the network cable and port configurations that must be followed for
SmartTrunking to operate properly. Before connecting the cables, refer to the
MATRIX
E7 Series and SmartSwitch 6000 Series Modules (6x2xx and 6x3xx) Local
Management User’s Guide
for the configuration information.
Leave the protective covers in place when the connectors are not in use to prevent
contamination.
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 fiber port cleaning swab saturated with
optical-grade isopropyl alcohol may also be used to clean the ends.
