The following table lists the major FRUs shown in the illustration above and identifies which FRUs are
also self-service CRUs or optional-service CRUs.
Notes:
• Self-service CRUs: These CRUs are secured by no more than two screws. Examples of these CRUs
include the keyboard, the mouse, USB devices, and the power cord. Other self-service CRUs depending
on product design might include memory modules, adapter cards, hard disk drives, and optical drives.
• Optional-service CRUs: These CRUs are isolated parts within the computer and are concealed by an
access panel that is typically secured by more than two screws. Once the access panel is removed, the
specific CRU is visible.
