Connecting to the Network
The I3H-4FX-MM, I3H-8FX-MM, I3H-4FXM-MEM, and I3H-8TX-2FX IOMs support 100BASE-FX
ports (Multimode). Each port is an LC connector. This section describes how to connect
100BASE-FX multimode fiber-optic segments from the network or other devices to an LC port
connector.
Each fiber-optic link consists of two fiber-optic strands within the cable for Transmit (TX) and
Receive (RX). The transmit strand from a device port connects to the receive port of a fiber-optic
Gigabit Ethernet device at the other end of the segment. The receive strand of the applicable LC
port connects to the transmit port of the fiber-optic Gigabit Ethernet device.
Enterasys recommends labeling fiber-optic cables to indicate receive and transmit ends. Many
cables are pre-labeled, providing matching labels or tapes at both ends of each strand of cable.
Refer to
To connect an LC cable connector to a fixed LC connector:
1. Remove the protective covers (not shown) from the front panel LC fiber-optic port and from
the connectors on each end of the cable.
2. Insert the LC cable connector into the LC connector until it clicks into place.
2-26 Installation
Figure 2-20 on page 2-27 as you perform the following procedure.
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 fiber-port 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 losextremos de los cables de fibra óptica
se ensucian, utilice aire comprimido paralimpiarlos. También puede limpiarlos con un estropajo
embebido en alcohol isopropílico.
Note: To prevent contamination, leave the protective covers in place when the connectors are not in
use.
Note: To remove the LC cable connector, press on its release tab and pull it out of the LC
connector.
