5-Port Gigabit Ethernet SPA LEDs
The 5-Port Gigabit Ethernet SPA has two types of LEDs: an A/L LED for each individual port and a
STATUS LED for the SPA, as shown in

5-Port Gigabit Ethernet SPA Cables and Connectors
The 5-Port Gigabit Ethernet SPA has five electrical connectors that support SFP modules. Each port can
send and receive traffic using cabling appropriate for the SFP module inserted.
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 5-Port Gigabit Ethernet SPA, linking the port with a fiber-optic network.
Note
The 5-Port Gigabit Ethernet SPA accepts only the SFP modules listed as supported in this document. An
SFP module check is run every time an SFP module is inserted into the 5-Port Gigabit Ethernet SPA, and
only SFP modules that pass this check can be used by the 5-Port Gigabit Ethernet SPA.
SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 5-Port
Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that plug
into the 5-Port Gigabit Ethernet SPA ports.
