How do I install ethernet cable?

For most backbone installations, it is common to install more cabling or fiberoptic pairs than are initially necessary, even if there is no immediately projected need for the additional cabling. This is done because the cost of labor is much higher than that of the cable and avoids the need for a complete rewiring with more cable, if networking needs change. Link aggregation can allow the use of these extra cables to increase backbone speeds for little or no extra cost.
