Cautions
These warnings and cautions apply throughout this chapter. Only a technically qualified person
should configure the server board.
CAUTIONS
System power on/off: The power button DOES NOT completely turn off
the system AC power, 5V standby is still active whenever the system is
plugged in. To remove power from system, you must unplug the AC power
cord from the wall outlet. Make sure the AC power cord is unplugged before
you open the chassis, add, or remove any components.
Hazardous conditions, devices & cables: Hazardous electrical
conditions may be present on power, telephone, and communication cables.
Turn off the server and disconnect the power cord, telecommunications
systems, networks, and modems attached to the server before opening it.
Otherwise, personal injury or equipment damage can result.
Electrostatic discharge (ESD) & 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 groundany unpainted metal surfaceon your server
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 server, place the
board 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.
