Notes:
1. The RS0/RS1 PU/PD resistors are not populated. There are pull-down resistors built into the zSFP modules that select
the lower bandwidth mode of the module.
2. BW selection is also available through I2C control.
For additional information about the zSFP module, see SFF-8402 and SFF-8432 on the
