The value of tmnxEsaHostPortNicDDMSupVoltage indicates the current supply voltage of the SFF. For 100G MSA Transponder, the supply voltage is in millivolts (mV). For all other types the voltage is in deci-millivolts (1/10th of a millivolt or 100 microvolt units). The formula for translating between the value of tmnxEsaHostPortNicDDMSupVoltage and Voltage is: Internally Calibrated only: tmnxEsaHostPortNicDDMSupVoltage * conversion_factor For example (internally calibrated SFF): 1. For 100G MSA transponders, the SNMP value 32851 is 32.851 Volts (V). 2. For all others, the SNMP value 32851 is 3.2851 Volts (V).
