Fat Pipe Switch Module
The fat pipe switch module is a plug-over module that provides a high-speed interconnect
between the AMC modules, the ATCA high-speed fabric ports, the processor, and the
Ethernet core switch or the PCIe switch on the KAT4000. There are four configurations of
the fat pipe switch module: GbE, 10 GbE-1 GbE, 10 GbE-10 GbE and sRIO.
Note: The 10 GbE-10 GbE and sRIO modules are not yet available for order.
All fat pipe switch configurations support:
• Four ports connected from each AMC site to the fat pipe switch capable of
interchangeably using GbE, sRIO or 10 GbE protocols
• Eight GbE 1000Base-BX (SerDes) ports connected from the backplane high-speed fabric
to the fat pipe switch
• Two ports connected from the fat pipe switch to Zone 3 for (optional) RTM access
The GbE and 10 GbE configurations also provide:
• One port for a dedicated GbE channel from the MPC8548 processor to the fat pipe
switch
• One port for a dedicated GbE channel from the Ethernet core switch to the fat pipe
switch
The sRIO configuration also provides:
• One or four ports for a dedicated sRIO channel from the MPC8548 processor to the fat
pipe switch
