Clarification needed on the rPDULoadStatusLoad SNMP OID.
Product Line

- AP78XX Metered Rack PDUs
- AP79XX Switched Rack PDUs
- All serial numbers
- rpdu firmware v3.5.8 and higher
- Utilizing SNMPv1 or SNMPv3 for load status information
Cause
Applicable to AP78XX and AP79XX 1G Rack PDUs only, object Identifier rPDULoadStatusLoad (.1.3.6.1.4.1.318.1.1.12.2.3.1.1.2) has a description: "This OID will return the phase/bank load measured in tenths of Amps". This will have different meaning across different types of rack mount power distribution units.
Resolution
On a single phase, single bank PDU there will only be one instance returned, which is the amp draw through the entire PDU.
