System damage
Computer hardware contains components that are sensitive to
electrostatic discharge. If you touch them without precautionary
measures, they can be destroyed.
Use a wrist strap connected to ground when accessing elec-
tronic parts and take care of grounding the system. Avoid
touching the internal components of the computer system.
Safety danger
Testing the fans is possible only with an opened casing and
the power turned back on. If you do not behave correctly,
serious injuries or death could be the consequences.
Once the power cables are plugged in again do not
touch anything else than the external power cords or
the power switch at the front of the system. Under no
circumstances reach inside the system.
After testing the fans switch off the power and dis-
connect the power cables immediately.
