Connecting to the Network
To connect an MT‐RJ cable to a fixed MT‐RJ connector of a Mini‐GBIC:
1. Remove the protective covers from the Mini‐GBIC MT‐RJ fiber‐optic port and from
the connectors on each end of the cable.
2. Insert the MT‐RJ cable connector into the MT‐RJ connector until it clicks into place.
3. Plug the other end of the cable into the appropriate port on the other device. Some
cables may be terminated at the other end with two separate connectors, one for each
fiber‐optic strand. In this case, ensure that the transmit fiber‐optic strand is connected
to the receive port and the receive fiber‐optic strand to the transmit port.
4. Verify that a link exists by checking that the port Link/Activity LED is on (blinking
green or solid green). If the Link/Activity LED is off, perform the following steps until
it is on:
a.
b. If there are separate fiber‐optic connections on the other device, check the
c.
If a link has not been established, refer to Chapter 4 for LED troubleshooting details. If
a problem persists, refer to "Getting Help" on page 1‐6 for details on contacting
Enterasys Networks for support.
5. Repeat steps 1 through 4, above, until all connections have been made.
3-26 Hardware Installation
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.
Note: To remove the MT-RJ cable connector, press on its release tab and pull out the
cable connector.
Verify that the device at the other end of the segment is powered ON and
connected to the segment.
crossover of the cables. Swap the cable connections if necessary.
Check that the fiber‐optic connection meets the dB loss and cable specifications
outlined in the Cabling Guide for multimode cabling. To obtain this document,
refer to "Related Documents" on page xiv.
