follows:
1. Removetheprotectivecovers(notshown)fromtheMT‐RJfrontpanelconnectorand
fromtheconnectoroneachendofthecable.
Note: An odd number of crossovers (preferably one) must be maintained between devices
so that the transmit port is connected to the receive port of the other device and vice versa.
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 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.
