SFP+ Ports

The Extreme Edge Server has five SFP+ ports on the front panel, each of which is directly
connected to the Ethernet switch. The front panel cages can accept 10GBase-SR (short
range) or 10GBase-LR (long range) SFP+ modules. Higher powered modules may require
SFP+ modules with industrial temperature limits. These ports include Synchronous
Ethernet support through the Ethernet switch. The I

1.8.3.1

Synchronous Ethernet PLL

The Extreme Edge Server has a Synchronous Ethernet (SyncE) PLL device on board that
allows a recovered clock from one SFP+ port to be used as the Ethernet timing reference
for the Ethernet switch. This allows the other SFP+ ports to be synchronized to this timing
reference. The diagram below shows the SyncE clocking architecture.
