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.
●
Some flat ribbon cables come prefolded. Never change the folds on these cables.
●
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 computer cover to push cables
down into the chassis. Always position the cables to lay properly by themselves.
When removing the power supply power cable from the P1 connector on the system board, always
follow these steps:
1. Squeeze on the top of the retaining latch attached to the cable end of the connector (1).
