Preventing static electricity discharge
Preventing static electricity discharge
The 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 by pressing and holding the power button on the front of the server
for several seconds, then unplug the power cords 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) and attach it to a
bare metal part of the server. You can also touch a bare metal surface on the back of
the server with your finger.
■ Avoid static-causing surfaces such as carpeted floors, plastic, and packing foam.
■ Avoid working on the server when your work area is extremely humid.
■ Remove components from their antistatic bags only when you are ready to use them.
Do not lay components on the outside of antistatic bags because only the inside of
the bags provide electrostatic protection.
■ Always hold expansion cards by their edges or their metal mounting brackets. Avoid
touching the edge connectors and components on the cards. Never slide expansion
cards or components over any surface.
Warning
To avoid exposure to dangerous electrical voltages and moving parts,
turn off your server and unplug the power cords and modem cable
before opening the server case.
Caution
ESD can permanently damage electrostatic discharge-sensitive
components in the server. Prevent ESD damage by following ESD
guidelines every time you open the server case.
Warning
To prevent risk of electric shock, do not insert any object into the vent
holes of the power supply module.
