Installing Optional Mini-GBICs

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 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.

To connect an MT‐RJ cable to a fixed MT‐RJ connector of a Mini‐GBIC, refer to Figure 3‐20 and proceed as follows:

1.Remove the protective covers (not shown) from the front panel MT‐RJ fiber‐optic port (port 27 in this example) and from the connectors on each end of the cable.

Note: Leave the protective covers in place when the connectors are not in use to prevent contamination.

.	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.

2.Insert the MT‐RJ cable connector into the MT‐RJ connector until it clicks into place.

Note: To remove the MT-RJ cable connector, press on its release tab and pull out the cable connector.
