Cables, Connectors, and Pinouts

The interface connectors on the 4-Port and 8-Port Fast Ethernet SPA are four or eight individual RJ-45
receptacles. You can use all interface connectors simultaneously. Each connection supports IEEE 802.3
and Ethernet 10/100BASE-T interfaces compliant with appropriate standards. Cisco Systems does not
supply Category 5 unshielded twisted-pair (UTP) RJ-45 cables; these cables are available commercially.

Note
the unused Category 5 UTP cable pairs 4/5 and 7/8. Common-mode termination reduces the
contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources. Wire
pairs 4/5 and 7/8 are actively terminated in the RJ-45 port circuitry in the 4-Port and 8-Port Fast Ethernet
SPA.
