SFP Control Signals
The SFP control signals, TX_DISABLE and RATE_SEL, are individually connected to the RTM
FPGA to allow control by the service processor. Refer to the
details.

10 Gbps SFP+ Ports
The RTM-ATCA-F125 provides a total of eight 10 Gbps SFP+ module sites. Six of these connect
to the fabric switch on the front-blade and two to the base switch.
4.4.1
Connectivity
The eight 10 Gbps XAUI ports from the front-blade connect to a pair of BCM8747 quad XAUI-
to-SFI phys which then connect to individual SFP+ connectors using an SFI interface as shown
in
Figure
4-3.
