Upgrades and Options
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: Internal support panel, proper cooling
and airflow. To prevent damage to the system board
from partially inserted processor/memory board and to
provide proper cooling and airflow, always install the
internal support panel for the processor/memory board
before installing the chassis side and top covers and
turning on the system. Operating the system without
this support panel in place can damage system parts.
