4.4.2 Front-Blade Port Mapping
The eight SFP+ sites are connected through phys to the front blade base and fabric
switches according to the following table.
4.4.3 BCM8747 Configuration Flash
The BCM8747 requires an external SPI Flash to store microcode for the internal
microcontroller. A single SPI Flash is connected to the FPGA and the SPI buses from each
BCM8747 are similarly connected to the FPGA. Register settings in the FPGA allow either
BCM8747 to connect to the SPI Flash as well as providing a programming port.
4.4.4 Transmitter Control
The TXONOFF signals on each BCM8747 are connected together to the RTM FPGA which
allows them to be driven under software control. This enables software to enable and
disable the SFP+ optical outputs.
4.4.5 BCM8747 Status
The PCMULK, PCDRLK, PLOSB and LASI signals from each BCM8747 port are
connected to the RTM FPGA to allow them to be monitored by software. The PLOSB and
LASI signals can also generate an interrupt to the front-blade. Refer to
Section 4.6, FPGA
on page 43
for further details.
