ATCA-F125 (6873M Artwork) Installation and Use (6806800J94N)
Functional Description
Functional Description
The SFP+ module receptacles are designed to support standard SFP modules, SFP+
modules as well as direct attach copper SFP+ cables. The following table lists the SFP+
module types that have been tested and verified for use on the ATCA-F125.

AMC Bay
The ATCA-F125 provides one AMC bay to support a processor AMC as an application
processor. The slot is connected by an AMC type B+ connector and supports a midsize
single width PrAMC module with access to an on board SATA drive and to a dual gigabit
Ethernet controller through the AMC.
Some PrAMC modules support 10Gb XAUI or 1Gb SGMII channels on ports 8-11 while
other PrAMCs will have PCI Express channels on ports 8-11. The ATCA-F125 has high
speed signal multiplexers to support routing of the AMC port 8-11 signals depending on the
PrAMC installed.
The ATCA-F125 also routes AMC ports 4-7 as a x4 PCIE port directly to a BCM5709s dual
MAC/PHY controller.
The ATCA-F125 provides current limiting power control to the AMC. A hot swap control
device is used to control the 12V payload power and 3.3V management power to the AMC
as well as providing current limiting.
The IPMC sets a control output pin to control the direction of a SATA mux. This determines
whether the service processor or the PrAMC has access to the SATA hard disk drive. The
SATA mux control from the IPMC is routed through the FPGA so that the SATA mux control
can be controlled by the service processor through the FPGA.
