Chapter 3 Overview: Cisco 7600 Series Router Shared Port Adapters
4-Port and 8-Port Fast Ethernet SPA Overview
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.
Figure 3-32 shows the RJ-45 connector. Table 3-21 lists the pinouts and signals for the RJ-45 connector.
Figure 3-32 RJ-45 Connections, Plug, and Receptacle
Note Referring to the RJ-45 pinout in Ta ble 3-21 , proper common-mode line terminations should be used for
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.
