Magnum DS50 / DS60s Dual Speed Hubs Installation and User Guide (06/02)
Media IEEE Standard Connector
Twisted Pair (CAT 3 or 5) 10BASE-T RJ-45
Twisted Pair (CAT 5) 100BASE-TX RJ-45
Fiber (Multi-mode) 100BASE-FX SC
Fiber (Single-mode) 100BASE-FX SC
NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10Mbps and
100Mbps) be used whenever possible in order to provide flexibility in a mixed-speed
network (since DS50 / DS60 hub ports are auto-sensing for either 10 or 100Mbps).
Note that the auto-sensing function does not sense the cable type.
3.2.1 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 an 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.
3.2.2 Connecting Fiber Optic SC-type, "Snap-In"
The following procedure applies to installations using SC-type fiber connectors. This
procedure applies to ports using multi-mode SC fiber connectors.
1. Before connecting the fiber optic cable, remove the protective dust cap / plug from the
end of the fiber connectors, exposing the ports opening. Save the dust cover / plug for
future use, in case the fiber cable needs to be unplugged for service.
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. Then,
insert the square male connector into the SC female jack of the Fiber port connector
until it clicks and secures.
Note: One strand of the duplex fiber optic cable may be coded using color bands
at regular intervals; you should use the color-coded strand on the associated ports
at each end of the fiber optic cable segment.
3. Connect the Transmit (TX) port on the Magnum 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. Note – the two male square-end SC cable strands may be fastened
together to plug as a unit.
4. Connect the Receive (RX) port to the Transmit (TX) port of the remote device. Use the
non-color coded fiber strand for this.
