Electrostatic discharge (ESD) sensitive devices, such as the PCIe cards, hard drives, CPUs, and memory cards, require special handling.
Wear an anti-static wrist strap when handling components such as disk drive assemblies, circuit boards, or PCIe cards. When servicing or removing server components, attach an anti-static strap to your wrist and then to a metal area on the server chassis. Following this practice equalizes the electrical potentials between you and the server.
In addition to wearing an anti-static wrist strap when handling components, create an ESD-free work place by using an anti-static mat as a work surface and as a place to set ESD-sensitive components such as printed circuit boards, DIMMs, and CPUs. You can use the following items as anti-static mats:
Anti-static bag used to wrap a replacement part
ESD mat (orderable from Oracle)
A disposable ESD mat (shipped with some optional system components)
