8-Port Fast Ethernet SPA Overview
8-Port FastEthernet SPA Cables, Connectors, and Pinouts
The interface connectors on the 8-Port FastEthernet SPA are eight individual RJ-45 receptacles. You can
use all eight 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.
