●
Keep cables clear of movable or rotating parts (such as the power supply and drive cage) to prevent
them from being cut or crimped when the component is lowered into its normal position.
●
In all cases, avoid bending or twisting the cables. Do not bend any cable sharply. 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 computer cover to push cables down
into the chassis. Always position the cables to lay properly by themselves or in the cable guides and
chassis areas designed for cable routing.
When removing the power supply power cable from the 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.
2. Grasp the cable end of the connector and pull it straight out.
CAUTION: Always pull the connector — NEVER pull on the cable. Pulling on the cable could damage
the cable and result in a failed power supply.
