asfollows:
1. Removethe���protectivecovers(notshown)fromtheMT‐RJfiber‐opticportonthe
Mini‐GBICandfromtheconnectorsoneachendofthecable.
2. InserttheMT‐RJcableconnectorintotheMini‐GBICuntilitclicksintoplace.
Note: When the fiber optic connectors of the Mini-GBICs are not in use, leave the
protective covers in place 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 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: To remove the MT-RJ cable connector, press on its release tab and pull it out of the
Mini-GBIC connector.
