2. (2)

   ‘Input/Output (I/O) device’ means a device, which provides data input and output capability between a server or a data storage product and other devices. An I/O device may be integral to the server motherboard or may be connected to the motherboard via expansion slots (such as Peripheral Component Interconnect, or Peripheral Component Interconnect Express);

3. (3)

   ‘motherboard’ means the main circuit board of F1a server or a data storage product. For purposes of this regulation, the motherboard includes connectors for attaching additional boards and typically includes the following components: processor, memory, BIOS, and expansion slots;

4. (4)

   ‘processor’ means the logic circuitry that responds to and processes the basic instructions that drive a server F2or a data storage product. For purposes of this regulation, the processor is the CPU of the server. A typical CPU is a physical package to be installed on the server motherboard via a socket or direct solder attachment. The CPU package may include one or more processor cores;

The total rated power output from any additional PSU outputs that are not primary and standby outputs shall be no greater than 20 Watts. PSUs that offer multiple outputs at the same voltage as the primary output are considered single-output PSUs unless those outputs:

    1. (a)

       are generated from separate converters or have separate output rectification stages, or

    2. (b)

       have independent current limits;

16. (16)

    ‘multi output PSU’ means a PSU designed to deliver the majority of its rated output power to more than one primary DC output for the purpose of powering a server or a data storage product. Multi output PSUs may offer one or more standby outputs that remain active whenever connected to an input power source. The total rated power output from any additional PSU outputs that are not primary and standby outputs shall be no greater than or equal to 20 Watts;
