Chapter 2 — Site Requirements
Power Consumption and Cooling Requirements The power and cooling
requirements for the library depend on the number and type of drives
installed. The following table provides the maximum power consumption
and heat load for the base library and for each additional component
added to the base library. Use this information to calculate the total
maximum power consumption and heat load values, which can be used to
build a power budget for the library.
All values are measured at the AC input and include power supply
efficiency. The values are averages of observed hardware. In general, the
lighter the load on the power supplies, the less efficient they are. The
power supply efficiency in turn affects the power draw of all components.
a. Includes two 24 VDC and two 5/12 VDC power supplies in the main frame, and two service frames each
b. Includes one 24 VDC power supply; no drives or RIMs installed.
c. No cartridge loaded.
