acdSfpThreshVccHighAlm
Module: ACD-SFP-MIB
OID (symbolic): ACD-SFP-MIB::acdSfpThreshVccHighAlm
OID (numeric): 1.3.6.1.4.1.22420.2.4.3.1.7
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: High Alarm transceiver supply voltage. Represented as a 16 bit unsigned integer with the voltage defined as the full 16 bit value (0 to 65535) with LSB equal to 100 micro-Volt, yielding a total range of 0 to +6.55 Volts.
What is acdSfpThreshVccHighAlm?
This OID stores the high-voltage alarm trigger point for the SFP power supply, represented as 0 to 65535 (0 to 6.55 volts). Network engineers use this to protect the transceiver from overvoltage damage due to power supply failures, typically set 0.2 volts above the module's nominal voltage (e.g., 3.5V for a 3.3V module). A value of 35000 represents 3.5 volts, so if supply voltage rises above this, an alarm is triggered.
