Cable Management
Proper routing of the internal cables is critical to the operation of the computer. 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.
●
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.
CAUTION: When disconnecting cables, always pull the connector - NEVER pull on the cable.
Pulling on the cable could damage the cable.
System board connectors are color-coded to make it easier to find the proper connection.
