Electrostatic Discharge Safety
ESD sensitive devices, such as the motherboard, PCIe2 cards, drives, 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.
■
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.
■
Use an Antistatic Mat
Place ESD-sensitive components such as the motherboard, memory, and other PCB cards on
an antistatic mat.
