2-Port Gigabit Ethernet SPA Overview
2-Port Fast Ethernet SPA Cables, Connectors, and Pinouts
The interface connectors on the 2-Port Fast Ethernet SPA are two individual RJ-45 receptacles. You can
use both the 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. The
RJ-45 connectors are shown in
Figure 2-14 .
Figure 2-14 2-Port Fast Ethernet RJ-45 Connections, Plug, and Receptacle
Table 2-16 lists the pinouts and signals for the RJ-45 connector.

2-Port Gigabit Ethernet SPA Cables and Connectors
The interface connectors on the 2-Port Gigabit Ethernet SPA are two individual fiber-optic receivers that
support SFP modules. Each port can send and receive traffic using the optical fiber connections.
SFP Module Connections
The small form-factor pluggable (SFP) module is an input/output (I/O) device that plugs into the Gigabit
Ethernet ports on the 2-Port Gigabit Ethernet SPA, linking the port with a fiber-optic network.
Note The 2-Port Gigabit Ethernet SPA will only accept the SFP modules listed as supported in this document.
An SFP module check is run every time an SFP module is inserted into the 2-Port Gigabit Ethernet SPA
and only SFP modules that pass this check will be usable by the 2-Port Gigabit Ethernet SPA.
