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.
