ESD Measures
ESD sensitive devices, such as the cards, drives, and DIMMS, require special handling.
Caution -
Circuit boards and 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 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.
