I2C Bus; Sfp Status Signals; Sfp Control Signals; Gbps Sfp+ Ports - Emerson RTM-ATCA-F140 Installation And Use Manual

Functional Description
4.3.3.1

I2C Bus

The SFP I2C bus signals (I2C_SDA and I2C_SCL) from each SFP site are individually connected
to the RTM FPGA. An I2C controller within the FPGA allows the front-blade service processor to
access these ports to obtain SFP status and diagnostic information. Refer to the
FPGA, on page 52
4.3.3.2

SFP Status Signals

The SFP status signals, MOD_ABS, TX_FAULT and LOS, are individually connected to the RTM
FPGA to allow monitoring by the service processor. Refer to the
details.
4.3.3.3

SFP Control Signals

The SFP control signals, TX_DISABLE and RATE_SEL, are individually connected to the RTM
FPGA to allow control by the service processor. Refer to the
details.
4.4

10 Gbps SFP+ Ports

The RTM-ATCA-F140 provides a two 10Gbps SFP+ module sites connected to the base switch
on the front blade.
