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 are not
designed to withstand excessive pressure.
• Keep cables clear of sliding or moveable parts to prevent cutting or crimping.
• When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
wires.
• Some flat ribbon cables come pre-folded. Never change the folds on these cables.
• Do not sharply bend any cable. A sharp bend can break the internal wires.
• Never bend a SATA data cable tighter than a 30 mm (1.18 in.) radius.
• Never crease a SATA data cable.
• Do not rely on components like the drive cage, power supply, or system cover to push cables
down into the chassis.
