Cable management

Proper routing of the internal cables is critical to the operation of the computer. Follow good cable
management practices when you have to remove and install components.
● Handle cables with care to avoid damage.
● Apply only the tension required to seat or unseat cables during insertion or removal from the
connector.
● When possible, handle cables by the connector or pull-strap.
● Route cables in such a way that they cannot be caught or snagged by parts being removed or
replaced.
● Keep cables away from direct contact with major heat sources, such as the heat sink. Some air flow
guides have a cable guide that lets you route cables safely around the heat sink.
● Do not jam cables on top of daughterboards or memory modules (DIMMs). Circuit cards and DIMMs
are not designed to take excessive pressure.
● Keep cables clear of any movable or rotating parts (such as a fan) 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.
● Do not rely on components like the keyboard or service door to push cables down internally. Always
position the cables to lie properly by themselves or in the cable guides and chassis areas designed
for cable routing.
IMPORTANT:
could damage the cable pins and result in a failed device.

Connector types

There are several types of connectors on the system board with different requirements for cable
removal or insertion.
IMPORTANT:

Flex cable

Use this information to properly use flex cables.
When connecting flex cables to a ZIF connector, rotate the latch to 90°, push the cable completely,
evenly into the connector, and then close the latch.
When removing flex cables from a ZIF connector on the system board, you must release the latch before
removing the cable. Always follow these steps:
1. Flip the connector latch 90° to release the cable.
2. Grasp the cable end of the connector and pull it straight out.
IMPORTANT:
could damage the cable pins and result in a failed device.
