Connecting to the Network
3-24 Hardware Installation
Each fiber‐optic link consists of two fiber‐optic strands within the cable:
•
Transmit (TX)
•
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.
To connect an LC cable connector to a fixed LC connector of an XFP, refer to
and proceed as follows:
1.
Remove the protective covers (not shown) from the front panel LC fiber‐optic port
(port 22 in this example) and from the connectors on each end of the cable.
2.
Insert the LC cable connector into the XFP
LC connector until it clicks into place.
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 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.
Note: Leave the protective covers in place when the connectors are not in use to prevent
contamination.
Note: To remove the LC cable connector, press on its release tab and pull it out of the XFP
LC
connector.
