[upsAdvConfig]
The OIDs in the [upsAdvConfig] category enable you to view or configure operating and shutdown
parameters for a UPS connected in smart-signalling mode. A Management Card can use all the OIDS
in this category. A PowerNet Agent can use all but four of the OIDs, as noted in the following table.
OID Task (page 1 of 3)
upsAdvConfigRatedOutputVoltage
1
Define the UPS nominal VAC output voltage. This value is
read-only for most 120 VAC UPSs.
upsAdvConfigHighTransferVolt
1
Define the input voltage at which the UPS will switch to its
AVR Boost feature
. If the UPS does not support AVR Boost,
it switches to battery operation instead. (A Matrix-UPS, for
example, does not support AVR Boost.)
upsAdvConfigLowTransferVolt
2
Define the input voltage at which the UPS will switch to its
AVR Trim feature
. If the UPS does not support AVR Trim, it
switches to battery operation instead. (A Matrix-UPS, for
example, does not support AVR Trim.)
upsAdvConfigAlarm Define when the UPS will generate an audible alarm for a
line-fail condition:
• timed (1): After the UPS switches to battery operation and
waits the delay defined by the
upsAdvConfigAlarmTimer OID.
• atLowBattery (2): When a low-battery condition occurs.
• never (3): No alarm occurs
upsAdvConfigAlarmTimer Define how long in seconds the UPS must wait after
switching to battery operation before it can generate an
alarm when timed (1) is the value for the
upsAdvConfigAlarm OID. The only allowed values are 0
and 30. If you use any value of 1 second or more, the value
is set to 30. If you use any value less than 1 second, the
value is set to 0.
upsAdvConfigMinReturnCapacity
2
Define the battery capacity (as a percentage of full capacity)
required before the UPS can return from a low-battery
shutdown.
1
If a SET specifies an unsupported value, the UPS interprets the value as the next lower allowed
value, as defined by the apcUpsConfigFieldValueRange OID in the tabled set of OIDs
{upsAdvConfigAllowedSetTable}. If the value is less than the lowest allowable value, the lowest
allowed value is used.
2
If a SET specifies an unsupported value, the UPS interprets the value as the next higher allowed
value, as defined by the apcUpsConfigFieldValueRange OID in the tabled set of OIDs
{upsAdvConfigAllowedSetTable}. If the value is higher than the highest allowable value, the
highest allowed value is used.
