• When removing or installing a component, use any available handles, ejector levers, or captive
installation screws. These devices prevent accidental removal, provide proper grounding for the
system, and help to ensure that bus connectors are properly seated.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohm (Mohm).
