18 MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL
MULTILINK MC-E10 & MC-E100 CONVERTER SWITCH
Note
It is recommended that high quality CAT. 5 cables (which work for both 10 Mbps and
100Mbps) be used whenever possible in order to provide flexibility in a mixed-speed
network, since P80-series switch ports are auto-sensing for either 10 and 100Mbps. Note
that the auto-cross function does not operate, if the port is fixed or not supporting auto-
negotiation.
4.8.0.1 Connecting Twisted Pair (RJ-45, CAT 3 or CAT 5, Unshielded or Shielded)
The following procedure describes how to connect a 10BASE-T or 100BASE-TX twisted pair
segment to the RJ-45 port. The procedure is the same for both unshielded and shielded
twisted pair cables.
1. Using standard twisted pair media, insert either end of the cable with a RJ-45
plug into the RJ-45 connector of the port. Note that, even though the
connector is shielded, either unshielded or shielded cables and wiring may be
used.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established. If
this does not help, ensure that the cable is connected properly and that the
device on the other end is powered and is not defective.
4. For Port # 1 or 1SW, if the LINK LED is not illuminated, move the switch which
has a cross-over or up-link for linking to another hub or Switch.
4.8.0.2 Connecting Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using ST-type fiber connectors. This
procedure applies to ports using multi-mode ST fiber connectors.
1. Before connecting the fiber optic cable, remove the protective dust caps from
the tips of the fiber connectors. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens
tissue dampened in alcohol. Make certain the connectors are clean before
connecting.
Note
One strand of the duplex fiber optic cable is coded using color bands at regular
intervals; you must use the color-coded strand on the associated ports at each end of
the fiber optic segment.
3. Connect the Transmit (TX) port (light colored post) on the Fiber port to the
Receive (RX) port of the remote device. Begin with the color-coded strand of
the cable for this first TX-to-RX connection.
4. Connect the Receive (RX) port (dark colored post) to the Transmit (TX) port of
the remote device. Use the non-color coded fiber strand for this.
