8-Port Gigabit Ethernet SPA Overview
8-Port Gigabit Ethernet SPA LEDs
The 8-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 Figure 3-21.
Figure 3-21 8-Port Gigabit Ethernet SPA Faceplate
Table 3-19 describes the 8-Port Gigabit Ethernet SPA LEDs.
8-Port Gigabit Ethernet SPA Cables and Connectors
The interface connectors on the 8-Port Gigabit Ethernet SPA are eight 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 8-Port Gigabit Ethernet SPA, linking the port with a fiber-optic network.
Note The 8-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 8-Port Gigabit Ethernet SPA, and
only SFP modules that pass this check can be used by the 8-Port Gigabit Ethernet SPA.
SFP modules exist for technologies other than Gigabit Ether
net and for products other than the 8-Port
Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that plug
into the 8-Port Gigabit Ethernet SPA ports.
