I made a simple template for the APC Netbotz AP9340, i currently have 2 (RJ45) temperature sensors connected and retrieving the temp and humidity from both. There are 4 Applications, 25 Items, 6 Triggers, and 3 Graphs.Applications:InformationReturn SideSupply SideThresholdsItems:AirflowCondensate Pump Run hoursCooling Demand PowerCooling output PowerCool Set PointDehumidify/OutputDew PointDischarge PressureFan. This template is for use with APC InRow Cooling Units. All fixed now!This APC Template contains outlet discovery and should work with any managed or switched APC PDU.Contains sane triggers, load status, graphs, etc.Triggers: APC Load State, Load. UPDATE: Uploaded V2 to fix one of the power ratings that was the wrong OID. Tested with:APC SURTD3000XLI with APC Network Management Card 2 (AP9630)APC SRT3000RMXLI with APC Network Management Card 2 (AP9630)EATON (PowerWare) 9125-6000g with ConnectUPS Web/SNMP Card. Configure appropriate alert threshholds to prevent spurious warnings.There is a UPS SNMP template for UPS with rfc-1628 support. Monitor the input voltage your UPS sees to determine whether it is within acceptable variance. In summary, AVR trim is a normal feature of APC Smart UPSs and should not affect the connected equipment. This is normal operation of the UPS reacting to too-high, or too-low voltage.” When the UPS switches to use this transformer, an internal relay makes a clicking sound. If your input is within acceptable parameters you can suppress these alerts by adjusting the Powerchute Agent parameters.ĪPC say: “AVR Trim is when the UPS uses the internal transformer to decrease input voltage which may be too high. Ideally you shouldn’t be seeing over around 253v regularly. UK mains AC is nominal 230v, but for various reasons the allowable actual voltage may be -6% / +10% of this. If you receive these alerts, the first thing to do is check the UPS status on the Powerchute console, from Device Properties > UPS Status, and verify the input voltage the UPS is seeing. Shortly after setting this up we began noticing strange events in the event logs and receiving UPS alert emails:Įmails: PowerChute Business Edition has detected the following event:Įxtended Overvoltage on Agent The other day we had to set up APC Powerchute UPS management software on a new server, as the server that previously ran it had been retired. We mentioned the importance of a good UPS in one of our first blogposts over a year ago, and now we come full circle to examining UPS again. An uninterruptible power supply as used in most server setups is an unremarkable and easily overlooked device.
