4.3.3.1 I

C Bus

The SFP I
connected to the RTM FPGA. An I
service processor to access these ports to obtain SFP status and diagnostic information.
Refer to the
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
for 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.
