3.1 Electrostatic Discharge Safety
Electrostatic discharge (ESD) sensitive devices, such as memory, the system board,
the PCI card, the SAS board, and the hard drives, require special handling.
Caution –
The 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 components. Do not touch the
components along their connector edges.
Caution – Wear an antistatic wrist strap and use an antistatic mat when handling
components such as drive assemblies, boards, or cards. When servicing or removing
server components, attach an antistatic strap to your wrist and then to a metal area
on the chassis.
