2 Hardware Installation . . . Warning: . . . . . Electrostatic discharge (ESD) can damage your system board, proces- sor, disk drives, add-in boards, and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some ESD protec- tion by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish and maintain contact with the system
