Connecting to the Network

b.If there are separate fiber‐optic connections on the other device, check the crossover of the cables. Swap the cable connections if necessary.

c.Check that the fiber‐optic connection meets the dB loss and cable specifications outlined in the Cabling Guide for multimode cabling. To obtain this document, refer to “Related Documents” on page xvi.

If a link has not been established, refer to Chapter 4 for LED troubleshooting details. If a problem persists, refer to “Getting Help” on page 1‐8 for details on contacting Enterasys Networks for support.

5.Repeat steps 1 through 4, above, until all connections have been made.

Connecting Fiber-Optic Cables to LC Ports

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.

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.
