Warning and Cautions!
These warnings and cautions apply whenever you remove the side cover of the system
to access components inside the system. Only a technically qualified person should
integrate and configure the system.
Warning!
System power on/off: The on/off button (a convex button) on the front panel
DOES NOT turn off the system AC power. To remove power from system, you
must unplug the AC power cord from the wall outlet or the system.
Hazardous conditions, power supply: Hazardous voltage, current, and energy
levels are present inside the power supply. There are no user serviceable parts
inside it; servicing should be done by technically qualified personnel.
Hazardous conditions, devices and cables: Hazardous electrical conditions may
be present on power, telephone, and communication cables. Turn off the system
and disconnect the power cords, telecommunications systems, networks, and
modems attached to the system before opening it. Otherwise, personal injury or
equipment damage can result.
Cautions!
Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives,
boards, and other parts. We recommend that you perform 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.
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. If you place the server board on a conductive surface, the battery
leads may short out. If they do, this will result in a loss of CMOS data and will drain the
battery. Use a conductive foam pad if available but not the board wrapper. Do not slide
board over any surface.
Cooling and airflow: For proper cooling and airflow, always install the chassis side
cover before turning on the system. Operating it without the cover in place can damage
system parts.
