ESD can damage disk drives, boards, and other
parts. This system can withstand normal levels of environmental
ESD while you are installing SCSI hard drives. However, we
recommend that you do all procedures in this chapter only at an
ESD workstation or provide some ESD protection by wearing
an antistatic wrist strap attached to chassis ground (any
unpainted metal surface) on your system when handling parts.
