Working Safely Inside the Mac Pro
Always touch the Mac Pro chassis while it is still plugged in to discharge static
electricity before you touch any components inside. To avoid generating static
electricity, do not walk around the room until you have finished working inside the Mac
Pro and have replaced the cover. To minimize the possibility of damage due to static
discharge, wear an antistatic wrist strap while you work inside the Mac Pro.
Hold printed circuit boards by their edges. Never touch the gold contacts
or other exposed metallic components on the boards. Handle the boards gently and
don’t bend or flex them.
