Caution: Electrostatic discharge (ESD) and ESD
protection. ESD can damage disk drives, boards, and
other parts. This system can withstand normal levels of
environmental ESD while you are hot-swapping SCSI
hard drives or hot-swapping a failed fan module or
power supply. However, we recommend that you do all
procedures in this chapter only at an ESD workstation.
If one is not available, provide some ESD protection by
wearing an antistatic wrist strap attached to chassis
ground any unpainted metal surface on your system
when handling parts
Caution: ESD and handling boards. Always handle
boards carefully. They can be extremely sensitive to
ESD. Hold boards only by their edges. After removing a
board from its protective wrapper or from the system,
place it component-side up on a grounded, static-free
surface. Use a conductive foam pad if available but not
the board wrapper. Do not slide board over any surface.
Caution: Chassis covers, proper cooling and
airflow. For proper cooling and airflow, always install
the chassis side and top covers before turning on the
system. Operating it without these covers in place can
damage system parts.
Contact your sales representative or dealer for a list of
approved optional peripheral devices.
