Tools Needed for Service
Caution -
Circuit boards and hard drives contain electronic components that are extremely
sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work
environment can destroy the components located on these boards. Do not touch the components
along their connector edges.
Caution - You must disconnect all power supplies before servicing any of the components that
are inside the chassis.
Antistatic Wrist Strap Use
Wear an antistatic wrist strap and use an antistatic mat when handling components such as
hard drive assemblies, circuit boards, or express modules. 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.
Antistatic Mat
Place ESD-sensitive components such as motherboards, memory, and other PCBs on an
antistatic mat. These items can be used as an antistatic mat:
■
Antistatic bag used to wrap a replacement part
■
ESD mat
■
A disposable ESD mat (shipped with some replacement parts or optional system
components)
