4.9 SFP+ Modules
The ATCA-7470 provides four SFP+ module receptacles on the front panel, two for base uplinks
and two for fabric uplinks. The SFP+ signals LOS, TX_FAULT and MOD_ABS are monitored for
status by the BCM8747 PHY. Status changes will result in a service processor interrupt.
Each SFP+ module's I2C signals are routed to the BCM8747 PHY which provides four separate
SFP+ I2C interfaces. The service processor uses these I2C interfaces, accessed through the PHY
management port, to read the module's on-board EEPROM information to determine type and
vendor specific information.
The individual TXONOFF signals on the BCM8747 are connected to the FPGA which allows
them to be driven under software control. This enables software to individually enable and
disable the SFP+ optical outputs.
