Enterasys Networks A2H254-16 manual Connecting Fiber-Optic Cables to MT-RJ Mini-GBIC Ports

Connecting to the Network

3.Verify that a link exists by checking that the Link/Activity LED is ON (solid green or blinking green). If the Link/Activity LED is OFF, perform the following steps until it is on:

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

b.Verify that the fiber connection meets the dB loss and cable specifications for multimode cabling, as outlined in the Cabling Guide. Refer to “Related Documents” on page xiv for information on obtaining this document.

4.If a link is not established, contact Enterasys Networks. Refer to “Getting Help” on page 1‐6 for details.

Repeat all steps above until all connections have been made.

Connecting Fiber-Optic Cables to MT-RJ Mini-GBIC 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 contains the procedures for connecting a 1000BASE‐SX multimode fiber‐optic segment from the network or other device to an MT‐RJ port connector in a Mini‐GBIC (MGBIC‐MT01).

Each fiber‐optic link consists of two fiber‐optic strands within the cable:

•Transmit (TX)

•Receive (RX)

The transmit strand from the MT‐RJ 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 MT‐RJ port connects to the transmit port of the fiber‐optic Gigabit Ethernet switch.

Enterasys Networks 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.
