ESD Precautions
ESD-sensitive devices, such as the PCIe cards, hard drives, and DIMMs require special
handling.
Caution - Circuit boards and hard drives contain electronic components that are extremely
sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work
environment can destroy the components located on these boards. Do not touch the components
along their connector edges.
Caution - You must disconnect all power supplies before servicing any of the components that
are inside the chassis.
