●
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 cables 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 up.
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.
Power connections
For help with identifying power cables, see the following figure and table. Ensure that all cables are
routed or tied so they cannot interfere with the processor heatsink fans.
