Place electrostatic discharge (ESD)-sensitive components such as the printed circuit boards on an antistatic mat. The following items can be used as an antistatic mat:
An antistatic bag used to wrap a replacement part
An Oracle ESD mat (orderable item)
A disposable ESD mat (shipped with some replacement parts or optional system components)
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.
