Air Circulation; Electrical Outlets And Cable Lengths - IBM NetVista A21 Quick Reference

Air circulation

Your computer and monitor produce heat. The computer has a fan that pulls in
fresh air and forces out hot air. The monitor lets hot air escape through vents.
Blocking the air vents can cause overheating, which might result in a
malfunction or damage. Place the computer and monitor so that nothing blocks
the air vents; usually, 51 mm (2 in.) of air space is sufficient. Also, make sure
the vented air is not blowing on someone else.

Electrical outlets and cable lengths

The location of electrical outlets and the length of power cords and cables that
connect to the monitor, printer, and other devices might determine the final
placement of your computer.
When arranging your workspace:
v Avoid the use of extension cords. When possible, plug the computer power
cord directly into an electrical outlet.
v Keep power cords and cables neatly routed away from walkways and other
areas where they might get kicked accidentally.
For more information about power cords, see the "Power cord notice" section
in this book.
