Making RJ-45 Connections
1.Prepare a straight-through twisted-pair cable with RJ-45 plugs at both ends.
2.If you are making a connection to a server or workstation (i.e., a dedicated connection to an end-node device), be sure that it has a properly installed 100BASE-TX or 10BASE-T network interface card. Attach one end of the cable to the MDI-Xstation port on the switch and the other end to the RJ-45 port of the device’s network interface card. As a general rule, the length of twisted-pair cable forming a direct link between any two network devices should not exceed 100 meters.
Note: Category 5 twisted-pair cable (100W) must be used for 100Mbps connections. Although Category 3, 4 or 5 cable can be used for 10Mbps connections, we highly recommend that you also use Category 5 cable for these connections to avoid any unnecessary expense or confusion if you subsequently upgrade to Fast Ethernet.
If you are connecting to a network interconnection device, attach one end of the cable to the MDI crossover port on the switch and the other end to an MDI-Xstation port on the other device (or vice versa). When cascading to devices other than this switch, please refer to the accompanying documentation for restrictions on stack size. Also note that because the switch breaks up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.
Note: In contrast to repeater hubs, a cascade of switches breaks up the collision domain. The number of switches that can be cascaded is therefore theoretically unlimited. However, in practice, the length of a cascade may be limited by the time- out requirements of the particular applications running over the network.
3.Set the communication mode via the Configure button to full-duplex or half-duplex mode to match the connected device. (Refer to Setting the
Communication Mode in Chapter 3.)
ΙDo not plug a phone jack connector into the RJ-45 port. This may damage the switch. Instead, use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.
