Determining PDU Requirements
Using the nominal voltage rating of the power receptacle at your site and the total
wattage of the components that will draw power from the A-side PDU, complete the
. This information will help you determine the current
that the ftServer systems and rack-mounted components will draw and whether you
need a second pair of PDUs.
1. Obtain the voltage available at your location. Consult a facilities manager at your
site to make sure you know the correct voltage.
2. For each type of component you plan to place in the rack, calculate the required
current, as follows: Divide the wattage of the element, listed in the Watts column of
, by the voltage available at your site. Multiply the result by 1.25 and enter
the value in the
Current
column.
