Installing Optional Mini-GBICs
3-30 Hardware Installation
Connecting Fiber-Optic Cables to LC Ports
This section describes how to connect
• a 1000BASE‐SX multimode fiber‐optic segment from the network or other devices to
an LC port connector of a Mini‐GBIC (MGBIC‐LC01), or
• a 1000BASE‐LX single‐mode fiber‐optic segment from the network or other devices to
an LC port connector of a Mini‐GBIC (MGBIC‐LC09).
Each fiber‐optic link consists of two fiber‐optic strands within the cable:
• Transmit (TX)
• Receive (RX)
The transmit strand from a switch 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 a Mini‐GBIC, refer to
Figure 3‐21 and proceed as follows:
Warning: Fiber-optic Mini-GBICs use Class 1 lasers. Do not use optical instruments to
view the laser output. The use of optical instruments to view laser output increases eye
hazard. When viewing the output optical port, power must be removed from the network
adapter.
Advertencia: Los Mini-GBICS de fibra optica usan lasers de clase 1. No se debe usar
instrumentos opticos para ver la potencia laser. El uso de los instrumentos opticos para
ver la potencia laser incrementa el riesgo a los ojos. Cuando vean el puerto de la potencia
optica, la corriente debe ser removida del adaptador de la red.
Warnhinweis: Mini-GBICs mit Fiber-Optik Technologie benutzen Laser der Klasse 1.
Benutzen sie keinesfalls optische Hilfsmittel, um die Funktion des Lasers zu überprüfen.
Solche Hilfsmittel erhöhen die Gefahr von Sehschäden. Wenn sie den optischen Port
überprüfen möchten stellen Sie sicher, dass die Komponente von der
Spannungsversorgung getrennt ist.
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.
