Do not step on or stand on any component when servicing other components in a rack.
Preventing static electricity discharge
The components inside your computer are extremely sensitive to static electricity, also known as
electrostatic discharge (ESD).
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.
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.
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.
Warning To prevent risk of electric shock, do not insert any object
into the vent holes of the power supply.
