§ 15.102   CPU boards and power supplies used in personal computers.

   (a) Authorized CPU boards and power supplies that are sold as separate
   components shall be supplied with complete installation instructions. These
   instructions shall specify all of the installation procedures that must be
   followed to ensure compliance with the standards, including, if necessary,
   the type of enclosure, e.g., a metal enclosure, proper grounding techniques,
   the use of shielded cables, the addition of any needed components, and any
   necessary modifications to additional components.

   (1) Any additional parts needed to ensure compliance with the standards,
   except for the enclosure, are considered to be special accessories and, in
   accordance with § 15.27, must be marketed with the CPU board or power supply.

   (2) Any modifications that must be made to a personal computer, peripheral
   device, CPU board or power supply during installation of a CPU board or
   power supply must be simple enough that they can be performed by the average
   consumer. Parts requiring soldering, disassembly of circuitry or other
   similar modifications are not permitted.

   (b) Assemblers of personal computer systems employing modular CPU boards
   and/or power supplies are not required to test the resulting system provided
   the following conditions are met:

   (1) Each device used in the system has been authorized as required under
   this part (according to § 15.101(e), some subassemblies used in a personal
   computer system may not require an authorization);

   (2) The original label and identification on each piece of equipment remain
   unchanged;

   (3) Each responsible party's instructions to ensure compliance (including,
   if  necessary,  the  use  of  shielded  cables or other accessories or
   modifications) are followed when the system is assembled;

   (4)  If the system is marketed, the resulting equipment combination is
   authorized under a Declaration of Conformity pursuant to § 15.101(c)(4) and a
   compliance information statement, as described in § 2.1077(b), is supplied
   with the system. Marketed systems shall also comply with the labelling
   requirements in § 15.19 and must be supplied with the information required
   under § § 15.21, 15.27 and 15.105; and

   (5) The assembler of a personal computer system may be required to test the
   system and/or make necessary modifications if a system is found to cause
   harmful interference or to be noncompliant with the appropriate standards in
   the configuration in which it is marketed (see § § 2.909, 15.1, 15.27(d) and
   15.101(e)).
