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 # 8, if the LINK LED is not illuminated, exchange the RJ-45 wiring
plug with port # 8X which has a cross-over or up-link connector for linking to
another hub.
