Cable management

Always follow good cable management practices when working inside the computer.
● Keep cables away from major heat sources like the heat sink.
● Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these are not
designed to take excessive pressure on them.
● Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the parts
are moved.
● When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.
Some flat ribbon cables come prefolded. Never change the folds on these cables.
●
● Do not bend any cable sharply. A sharp bend can break the internal wires.
● Always position the cables to lay properly by themselves.
