4.4.5 BCM8727 Status
The PCMULK, PCDRLK, PLOSB and LASI signals from each BCM8727 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
FPGA on page 67
for further details.
4.4.6 SFP+ Connection
The SFP+ module receptacles are designed to support standard SFP+ modules and direct
attach copper SFP+ modules less than 10m in length. The SFP+ cage is backwards
compatible with 1GB optical or copper SFP modules. Refer to the
ATCA-F140 Installation
and Use Manual
for a list of SFP devices tested with this product. The SFP+ connector
assignment for the 10Gbps serial interface is described in
Table 4-6
.

C bus signals (I2C_SDA and I2C_SCL) from each SFP+ site are individually
connected to the corresponding BCM8727 which includes a mechanism to allow access to
the port through the PHY management channel.
