A column in the sfpInventoryTable, with the following code points. noError - valid values for all objects in this row (e.g. sfpDiagRxPower) were obtained from the SFP in the specified cage. cageEmpty - the specified SFP cage does not contain an SFP. All subsequent values in the row have notAvailable or 'Not Available' values. cageDoesNotSupportA2 - the specified SFP cage does not support access to the SFP A2 bank (e.g. because of limitations in FPGA support on the host card). sfpDiagLOS and sfpDiagTxFault have valid values (since they are implemented using external signals, not SFP EEPROM values). a0ReadFailed - the attempt to read the A0 bank of the specified SFP failed. A0 is read to determine if A2 is supported, so no attempt was made to read the A2 information. sfpDiagLOS and sfpDiagTxFault have valid values (since they are implemented using external signals, not SFP EEPROM values). a0ChecksumFailed - the A0 bank of the SFP EEPROM is corrupted. sfpDiagLOS and sfpDiagTxFault have valid values (since they are implemented using external signals, not SFP EEPROM values). sfpDoesNotSupportA2 - the A0 bank of the SFP EEPROM indicates A2 is not supported. sfpDiagLOS and sfpDiagTxFault have valid values (since they are implemented using external signals, not SFP EEPROM values). a2ReadFailed - the attempt to read the A2 bank of the specified SFP failed. sfpDiagLOS and sfpDiagTxFault have valid values (since they are implemented using external signals, not SFP EEPROM values). a2ChecksumFailed - the A2 bank of the SFP EEPROM is corrupted. sfpDiagLOS and sfpDiagTxFault have valid values (since they are implemented using external signals, not SFP EEPROM values).
