sheEthernetPortSfpSupplyVoltage
Module: SHE-ETHERNET-MIB
OID (symbolic): SHE-ETHERNET-MIB::sheEthernetPortSfpSupplyVoltage
OID (numeric): 1.3.6.1.4.1.231.7.1.2.2.1.5.1.1.1.22
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Internally measured transceiver supply voltage. Represented as a 16 bit unsigned integer with the voltage defined as the full 16 bit value (0 .. 65535) with LSB equal to 100 Volt, yielding a total range of 0 to +6.55 Volts. Practical considerations to be defined by transceiver manufacturer will tend to limit the actual bounds of the supply voltage measurement. Accuracy is vendor specific but must be better than 3% of the manufacturers nominal value over specified operating temperature and voltage. Note that in some transceivers, transmitter supply voltage and receiver supply voltage are isolated. In that case, only one supply is monitored.
Only valid if sheEthernetPortSfpDiagnosticValid entry is true.
What is sheEthernetPortSfpSupplyVoltage?
This read-only Unsigned32 (0-65535, in units of 100 microvolts per SFF-8472 table 3.17) reports the SFP transceiver's internally measured supply voltage, valid only when sheEthernetPortSfpDiagnosticValid is true. An admin monitors this to catch a failing or out-of-spec power supply to the optical module before it causes intermittent link problems. A supply voltage reading noticeably outside the module's nominal rated value would prompt an admin to investigate the SFP or its power source.
