Using an Antistatic Wrist Strap
Wear an antistatic wrist strap and use an antistatic mat when handling components
such as hard drive assemblies, circuit boards, or PCIe 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 not shipped with the servers. However, antistatic
wrist straps are included with options.
Using an Antistatic Mat
Place ESD-sensitive components on an antistatic mat.
ESD Handling Procedure
1. Prepare an antistatic surface to set parts on during the removal, installation, or

antistatic mat. The following items can be used as an antistatic mat:
■ Antistatic bag used to wrap a Sun replacement part
■ Sun ESD mat, part number 250-1088
■ A disposable ESD mat (shipped with some optional system components)
2. Attach an antistatic wrist strap.
When servicing or removing server components, attach an antistatic strap to your
wrist and then to a metal area on the chassis.
