2-Port Gigabit Ethernet SPA Overview
2-Port Gigabit Ethernet SPA LEDs
The 2-Port Gigabit Ethernet SPA has two types of LEDs: an A/L LED for each port and a STATUS LED,
as shown in
Figure 2-12
.
Figure 2-12 2-Port Gigabit Ethernet SPA Faceplate
Table 2-13
describes the 2-Port Gigabit Ethernet SPA LEDs.
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.
