How to Control a UPS

You can use SETs (SNMP write commands) to the [upsControl] OIDs to directly affect the current

operation of the UPS

[upsControl] OIDs

Which [upsControl] OIDs you can use depends on how the UPS connects to the network. The

[upsControl] category has two subcategories

• [upsBasicControl] for simple-signalling connections.

• [upsAdvControl] for smart-signalling connections.

[upsBasicControl]

The [upsBasicControl] category has one OID, which any Management Card or PowerNet Agent can

use to put a UPS that is running on battery into “sleep mode.”

OID Information Reported

upsAdvOutputVoltage The output voltage of the UPS in VAC.

upsAdvOutputFrequency The output voltage frequency of the UPS in Hertz.

upsAdvOutputLoad The equipment load placed on the UPS by its supported equipment as a

percentage of rated load capacity.

upsAdvOutputCurrent The output voltage current in Amperes

OID Task

upsBasicControlConserveBattery Cause a UPS running on battery to turn off its outlets to

conserve battery runtime and then wait in “sleep mode” until

acceptable input power returns.

• noTurnOffUps (1): The value always returned for a GET.

Setting this value has no effect.

• turnOffUpsToConserveBattery (2): The UPS, if running

on battery, waits in “sleep mode” until acceptable input

power returns. If the UPS is not on battery, a badValue error

is returned.
