2-Port Gigabit Synchronous Ethernet SPA Overview
2-Port Gigabit Synchronous Ethernet SPA LEDs
The 2-Port Gigabit Synchronous Ethernet SPA is a half-height SPA with these LEDs:
SPA status LED
Line status LED - A bi-color, surface-mount, right-angle LED dedicated to each SFP, RJ-45 and
coax connector to indicate port status
Debug LED
Table 3-33
describes the 2-Port Gigabit Synchronous Ethernet SPA LEDs.

2-Port Gigabit Synchronous Ethernet SPA Faceplate
2-Port Gigabit Synchronous Ethernet SPA Interface Specifications
The 2-Port Gigabit Synchronous Ethernet SPA is compatible with the 2-Port Gigabit Ethernet SPA on
all platforms and provides additional services of clock frequency and time of day synchronization.
The2-Port Gigabit Synchronous Ethernet SPA uses new technologies such as Synchronous Ethernet
(SyncE), ESMC, and IEEE1588v2.
However, the 2-Port Gigabit Synchronous Ethernet SPA supports only optical interfaces. As a result the
2-Port Gigabit Synchronous Ethernet SPA does not support multiple line speeds (10/100/1000 Mbps) on
the 2-Port Gigabit Ethernet SPA.
Synchronous Ethernet is a layer 1 technology which delivers a very accurate frequency reference, but it
doesn't address time synchronization. IEEE1588v2 defines a Precision Time Protocol (PTP),which
distributes accurate timing information (both clock frequency and time of day) over packet networks.
