Grounding Requirements
Due to electromagnetic interference (EMI) filtering in each dual AC power
supply, the leakage current for main frames and drive frames is such that
they require a secure connection from the frame chassis to an earth ground.
Use one of the following methods for securing a ground connection when
installing a main frame or drive frame:
 Add cord lock brackets (Spectra Logic part number 5497) to all drive
 Use a cord with locking connectors at both ends, such as L6 20P to
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.
