SFP_TX_FAULT Test Point J65
High = Fault
zSFP3 J6
Low = Normal operation
SFP_TX_DISABLE Jumper J54
Off = SFP Disabled
On = SFP Enabled
SFP_MOD_DETECT Test Point J66
High = Module not present
Low = Module present
SFP_RS0
(1)(2)
PU R589/ PD R605
PU R182 = Full RX bandwidth
PD R190 = Reduced RX bandwidth
SFP_RS1
(1)(2)
PU R590/ PD R606
PU R185 = Full RX bandwidth
PD R202 = Reduced RX bandwidth
SFP_LOS Test Point J67
High = Loss of receiver signal
Low = Normal operation
Notes:
1. The RS0/RS1 PU/PD resistors are not populated. There are pull-down resistors built into the SFP/zSFP modules that select
the lower bandwidth mode of the module.
2. Also available via I2C control. For this and additional information about the enhanced SFP+ module, see the SFF-8431
specification at the SFF-8431 specification website [Ref 29].
