Warning
Before working on the chassis, unplug the AC power cord.
Working in an ESD Environment
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs
when electronic components are improperly handled and can result in complete or intermittent failures.
Always follow ESD-prevention procedures when you remove and replace components. Ensure that the
chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it
makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to
safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and
cord must operate properly. If no wrist strap is available, ground yourself by touching the metal part of
the chassis.
