31UPS Network Management Card 2 User’s Guide
• In a list:
– Input Voltage: The AC voltage (VAC) being received by the UPS or, for 3-phase UPSs, by
each phase of the UPS.
– Output Voltage: The AC voltage (VAC) the UPS, or each phase of a 3-phase UPS, is
providing to its load.
– Ambient Temperature: The temperature of the air inside the input/output (I/O) enclosure of
the UPS.
– Runtime Remaining: How long the UPS can use battery power to support its load.
– Last Battery Transfer: The cause of the last switch to battery operation.
– Redundancy: The number of power modules which can fail or be removed without causing
the UPS to switch to bypass operation. For example, with n+2 redundancy, two power
modules could fail or be removed without causing the UPS to enter bypass mode.

Model-specific status displayed
To view detailed information about status items specific to the UPS model associated with the
Management Card, see the online help.
The types of model-specific information displayed include the following values, some of which are
reported by phase for 3-phase UPS models:
• Voltage, Current, and Frequency information, such as input and output voltage, input and
output current, input frequency, input voltage in bypass mode, and minimum and maximum input
voltage during the last minute.
• UPS Load information, such as the load placed on the UPS in kVA or as a percentage of
available kVA or Watts.
• Fault Tolerance information, such as redundant power available.
• Battery information, such as available battery capacity, percentage of full battery capacity,
battery output current, rated voltage capacity of batteries, amp-hour rating of battery cabinets,
number of batteries installed, and number of faulty batteries.
• Status of internal and external components, such as intelligence and power modules, circuit
breaker box, external switch gear, and transformer.
