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
Chapter 4, FPGA, on page 44 for further
details.
4.4.6 SFP+ Connection
The SFP+ cage accepts industry standard SFP+ optical modules. The SFP+ cage is backwards
compatible with 1 GB optical or copper SFP modules. Refer to the ATCA-F125 Installation and
Use Manual for a list of SFP devices tested with this product. The SFP+ connector assignment
for the 10 GB serial interface is described in
Table 4-6 .
4.4.6.1 I2C Bus
The SFP+ I2C bus signals (I2C_SDA and I2C_SCL) from each SFP+ site are individually connected
to the corresponding BCM8747 which includes a mechanism to allow access to the port
through the phy management channel.
