connection, and the LED is lit green when traffic is passing through the port.
The control board interface ports function as follows:
and
—Two SFP+ connects the CB-RE through an Ethernet to support 2 x
XGE-0
XGE-1
10-Gbps connections to any external control box. Two small LEDs on the side of each
SFP+ port indicate the connection in use: the LED flashes yellow when there is no link,
flashes green when there is activity, or is lit green for a 10-Gbps connection.
