41Preventing static electricity dischargewww.gateway.comPreventing static electricitydischargeThe components inside your server are extremely sensitive to static electricity,also known as electrostatic discharge (ESD).Before working with server components, follow these guidelines:■ Turn off the server, then unplug the power cord and all other cables.■ Press the power button to drain any residual power from the server.■ Wear a grounding wrist strap (available at most electronics stores) andattach it to a bare metal part of the server. You can also touch a bare metalsurface on the back of the server with your finger.■ Avoid static-causing surfaces such as carpeted floors, plastic, and packingfoam.■ Avoid working on the server when your work area is extremely humid.■ Remove components from their antistatic bags only when you are readyto use them. Do not lay components on the outside of antistatic bagsbecause only the inside of the bags provide electrostatic protection.■ Always hold expansion cards by their edges or their metal mountingbrackets. Avoid touching the edge connectors and components on thecards. Never slide expansion cards or components over any surface.Warning ESD can permanently damage electrostaticdischarge-sensitive components in the server. PreventESD damage by following ESD guidelines every time youopen the server case.Warning To avoid exposure to dangerous electrical voltages andmoving parts, turn off your server and unplug the powercord and modem cable before opening the server case.Warning To prevent risk of electric shock, do not insert any objectinto the vent holes of the power supply.
