these connections can be accomplished in a number of ways. the most important consideration is that when using a normal, straight-through cable, the connection should be made between a normal crossed port (ports 1-48) and an uplink (mdi-ii) port. if you are using a crossover cable, the connection must be made from a crossed port to another crossed port.

    a 10base-t hub or switch can be connected to the switch via a two-pair category 3, 4 or 5 utp/stp straight through cable.

    a 100base-tx hub or switch can be connected to the switch via a two-pair category 5 utp/stp straight through cable.

    if you are connecting to another switch or hub via an uplink port (mdi-ii) use a straight through cable as shown in figure 4-2 below.
