Electrostatic Discharge Safety
Devices that are sensitive to electrostatic discharge (ESD), such as the motherboard,
PCIe cards, drives, processors, and memory cards require special handling.
Caution – The boards and drives contain electronic components that are extremely
sensitive to static electricity. Ordinary amounts of static electricity from clothing or
the work environment can destroy components. Do not touch the components along
their connector edges.
Do the following when handling ESD-sensitive components:
■
Use an antistatic wrist strap.
Wear an antistatic wrist strap and use an antistatic mat when handling
components such as drive assemblies, boards, or cards. When servicing or
removing server components, attach an antistatic strap to your wrist and then to a
metal area on the chassis. Then disconnect the power cords from the server.
Following this practice equalizes the electrical potentials between you and the
server.
Note – An antistatic wrist strap is not included in the Ship Kit for the server.
However, antistatic wrist straps are included with options and components.

Use an antistatic mat.
