Gateway Unmanaged Ethernet Switch Preventing static electricity discharge

Important safety information

Do not step on or stand on any component when servicing other components in a rack.

Important A qualified electrician must perform all connections to DC power and to safety grounds. All electrical wiring must comply with applicable local or national codes and practices.

Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning	The switch chassis must be positively grounded to the rack
	cabinet frame. Do not attempt to connect power to the
	switch until grounding cables are connected. Completed
	power and safety ground wiring must be inspected by a
	qualified electrical inspector. An electrical hazard will exist
	if the safety ground cable is omitted or disconnected.

Preventing static electricity discharge

The components inside your computer are extremely sensitive to static electricity, also known as electrostatic discharge (ESD).

Warning ESD can permanently damage electrostatic discharge-sensitive components in your computer. Prevent ESD damage by following ESD guidelines every time you open the computer case.

Warning To avoid exposure to dangerous electrical voltages and moving parts, turn off your computer and unplug the power cord and modem and network cables before opening the case.

Before opening the computer case, follow these guidelines:

■Turn off your computer.

■Wear a grounding wrist strap (available at most electronics stores) and attach it to a bare metal part of your computer.

Warning To prevent risk of electric shock, do not insert any object into the vent holes of the power supply.
