Description: Monitors HP Networking device power supply operational status, input voltage, and redundancy state.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is POWERSUPPLY-MIB?

POWERSUPPLY-MIB is an HP (HPE) Networking enterprise MIB, part of HP's ICF (Internetworking Configuration Framework) family, that represents power supply entities in HP-managed switches. It exposes per-bay power supply hardware data including operational state, cumulative failure counts, temperature, voltage information, and current versus maximum wattage draw, along with an extended power supply (Xps) table for expansion units. This is explicitly a hardware health and capacity-monitoring MIB: it is used to catch a failed or overheating power supply and to see how close a chassis is running to its power budget. It ties into HP's ENTITY-MIB-based physical inventory via hpicfEntityPs, mapping each power supply to the overall chassis entity tree. It is typically deployed on HP ProCurve/Aruba/HPE managed switches equipped with redundant or hot-swappable power supply bays, and administrators can perform a POWERSUPPLY-MIB download to load these objects into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in POWERSUPPLY-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

HP/HPE ProCurve/Aruba networking switches

Monitoring Examples

hpicfPsTable/hpicfPsEntry rows indexed by hpicfPsBayNum expose hpicfPsState, hpicfPsFailures, hpicfPsTemp, and hpicfPsWattageCur versus hpicfPsWattageMax; an admin polling hpicfPsState transitioning to a failed value alongside a rising hpicfPsFailures count would be alerted to a bad power supply, while hpicfPsWattageCur approaching hpicfPsWattageMax would flag a chassis nearing its power budget as modules are added. hpicfXpsTable/hpicfXpsEntry extend the same monitoring to expansion or auxiliary power supply units.

What Can Be Monitored

power supply operational state
power supply failure count
power supply temperature
input voltage
current/max wattage draw
redundant/expansion PS status

How to Use in IPNetwork Monitor

Example using hpicfPsFailures OID:

Select an HP/HPE ProCurve/Aruba networking switch (power supply entity status) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hpicfPsFailures into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the number of times power supply has failed. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
