1.
Calculate the exact system configuration, including all known growth
plans.
2.
Determine the total power consumption (in-watts) of the configuration,
using the values in Table 3-2.
3.
If the system is to be powered by an AC UPS, multiply the total power
consumption figure by 1.5 to determine its Volt–Amp (VA) requirements.
4.
The total power consumption and Volt–Amp requirements should be
rounded up to the next multiple of 50 before being used to choose an AC
UPS or –48 VDC source.

The base cabinet includes VCU, CPU, floppy disk, fans, and PSU. All
Voice/system disk drives require the same amount of power, regardless
of their storage capacity.
The following example shows the calculation of the input power requirements
for an 8-port system, equipped with two line cards, one integration card, and
two voice/system disk drives.
