Wear an antistatic wrist strap and use an antistatic mat when handling components such as hard drive assemblies, circuit boards, or PCI cards. When servicing or removing server components, attach an antistatic strap to your wrist and then to a metal area on the chassis. Following this practice equalizes the electrical potentials between you and the server.
Note - An antistatic wrist strap is no longer included in the server accessory kit. However, antistatic wrist straps are still included with options.
