FatPipeSwitch Module: 10GbE-1GbE Fat Pipe Switch Module

Components and Features

The following is a summary of the 10 GbE-1GbE fat pipe switch module hardware components and features:

BCM56580 10 GbE-1GbE Switch:

The Broadcom BCM56580 is a Layer 2 and 3 network switch with sixteen GbE ports and four 10 GbE ports. The switch uses integrated XAUI SerDes for the 10 GbE ports to the ATCA fabric channels and a single SerDes lane for each 1 GbE port to the AMC modules, complying with the CX-4and PICMG 3.1 standards.Table 5-2 defines connectivity for the switch’s ports when the fat pipe module is installed on the KAT4000. For more information about this switch, reference theBCM56580 16-Port 2.5 GbE Multilayer Switch with Four 10-GbE/HiGig™ Ports Data Sheet at www.broadcom.com.

Fat PipeSwitch Module: 10GbE-1GbE Fat Pipe Switch Module

PEX 8111 PCIe to PCI Bridge:

The BCM56580 switch is managed by the PCIe connection from the MPC8548 via the PEX8111 bridge chip. The PCIe to PCI bridge supports forward and reverse transparent bridging between the PCIe and PCI buses. The bridge’s PCI Express port has a single x1 link with a maximum throughput of 250 MB/sec per transmit and receive direction. The PEX 8111 is compliant with the PCI Local Bus Specification (rev. 3.0), the PCI to PCI Bridge Architecture Specification (rev. 1.1), the PCI Express Base Specification (rev. 1.0a) and the PCI Express to PCI/PCI-XBridge Specification (rev. 1.0). For more information about this bridge, reference thePEX 8111 ExpressLane™ PCI Express to PCI Bridge Data Sheet at www.plxtech.com.

PLD: The PLD is the interface between the local bus, the BCM56580 switch, and the PEX 8111 PCIe to PCI bridge. It contains registers for fat pipe module control. For more information, see “10GbE-1GbE Fat Pipe Switch Module PLD.”

SPI SROM EEPROM:

The 128 Kb EEPROM is used to store PEX 8111 bridge configuration information.

 

JTAG:

A jumper allows the JTAG to bypass the switch and/or the PEX bridge. See Fig. 5-12 for

 

details.

LEDs: CR2 (green) andCR3-5(red) on the bottom side of the board are generic LEDs for use by the firmware.

High-SpeedConnectors:

J1 is a 120-pinhigh-speedconnector that provides an interface to the four AMC sites, the BCM56580 switch, and the PEX 8111 PCIe to PCI bridge. J2 is a180-pinhigh-speedconnector that provides an interface to the RTM channel, PCIe channel, PLD, the I2C connection to the processor, and Zone 2 via fabric channels 1 and 2.

J4 and J5 are PMC connectors that attach to a PCI analyzer for debug use only.

Reset: Reset of the 10GbE-1GbE fat pipe switch is shown inFig. 5-14.

Fat Pipe

Switch Module

Implementation

Fat Pipes: This region supports data path connections such as 10 GbE. It can carry large amounts of data without significantly degrading the speed of transmission.

x4: This refers to the link width of the port (the number of lanes that can be used to interconnect between two link partners).

The following diagram shows the implementation of the 10 GbE-10GbE fat pipe switch module on the KAT4000:

Figure 5-16: Signal Routing of the 10GbE-10GbE Fat Pipe Switch Module on the KAT4000

*If the GbE core switch is present, GbE routes from the fat pipe to the GbE core switch.

If the GbE core switch is not present, GbE routes from the fat pipe to the CPU.
