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.

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.
