Electrostatic Discharge (ESD)
CAUTION!
ESD CAN DAMAGE DRIVES, BOARDS, AND OTHER PARTS. WE RECOMMEND THAT YOU
PERFORM ALL PROCEDURES AT AN ESD WORKSTATION. IF ONE IS NOT AVAILABLE,
PROVIDE SOME ESD PROTECTION BY WEARING AN ANTI-STATIC WRIST STRAP AT-
TACHED TO CHASSIS GROUND -- ANY UNPAINTED METAL SURFACE -- ON YOUR SERVER
WHEN HANDLING PARTS.
Always handle boards carefully, they can be extremely sensitive to ESD. Hold boards only by
their edges without touching any components or connectors. After removing a board from its
protective ESD bag or from the system, place the board component side up on a grounded, static
free surface. Use a conductive foam pad if available but not the ESD bag. Do not slide the board
over any surface.
System power on/off: To service components within the server, please ensure the power has
been disconnected.
e.g. Remove the node from the server chassis (to disconnect power) or disconnect the power
from the server chassis.
Make sure the system is removed from the rack before opening the chassis, adding, or removing
any non hot-plug components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be present
on power, telephone, and communication cables. Turn off the system chassis and disconnect the
cables attached to the system before servicing the chassis. Otherwise, personal injury or equip-
ment damage can result.
Electrostatic discharge (ESD) and ESD protection: ESD can damage drives, boards, and
other parts. We recommend that you perform all procedures in this chapter only at an ESD work-
station. If one is not available, provide some ESD protection by wearing an antistatic wrist strap
attached to chassis ground (any unpainted metal surface on the server) when handling parts.
ESD and handling boards: Always handle boards carefully. They can be extremely sensi-tive to
electrostatic discharge (ESD). Hold boards only by their edges. After removing a board from its
protective wrapper or from the system, 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.
