The UPS provides an intelligent slot for internal or external network card. This special intelligent network
card can be compatible with popular software and hardware found on the web and in operating
systems. It can support operating systems such as HP Open View, IBM Netview, SUN Netmanager, etc.
This enables the UPS to provide instant UPS and power information over the network. Please contact
your reseller for additional details.
DETERMINING THE POWER REQUIREMENTS OF YOUR
EQUIPMENT
1.
Make sure the total Volt-Amp (VA) requirements of your connected equipment does not exceed
the maximum VA rating for the UPS. The maximum VA ratings are shown in the Specifications
section of this document.
2.
Ensure that the equipment plugged into the battery-powered outlets does not exceed the UPS
rated capacity. If UPS rated capacities are exceeded, an overload condition may occur and cause
the UPS to shut down and trip the circuit breaker.
3.
If the power requirements of your equipment are listed in values other than Volt-Amps (VA),
convert Watts (W) or Amps (A) into VA by doing the calculations below. Note: The equation
below only calculates the maximum amount of VA that the equipment can use, not what is
typically used by the equipment at any given time. Users should expect usage requirements to
be approximately 60% of the value to estimate power requirements:
Watts (W) x 1.43 = _____ VA or _____ Amps (A) x 230 Volts (V) = _____ VA
Add the totals for all of the equipment and multiply this total by 0.65 to calculate actual power
requirements.
Note:
Many factors can affect the amount of power that your computer system will require. The
total load that you will be placing on the battery-powered outlets should not exceed 85% of the
UPS capacity.
