RJ-45 station port cable requirements:
10BASE-T
100 ohm Category 3, 4, 5 UTP/STP cable
100BASE-TX
100 ohm Category 5 UTP/STP cable
1000BASE-T
100 ohm Category 5 UTP/STP cable or better
Straight-through cabling requirements
Under most conditions, the 5 station ports on the Switch accept normal, straight-through cables, i.e.,
standard UTP/STP cables, which are the only ones that can be used with a RJ-45 pin layout.
Normally, 10BASE-T networks require a straight-through Cat. 3, 4, 5 UTP/STP cabling system.
The cabling system could be found in most existing Ethernet network installations.
100/1000BASE-T networks require Cat. 5 UTP/STP cabling system. The pin assignments for a
straight-through cable are shown in Figure 3-5 and 3-6.
