Intertwined

Bent

■The bending radius of cable body cannot be less than twice of the cable diameter. The bending radius of the cable cannot be less than 5 times of its diameter at the place where it is led out of the connector;

■Different cables (power cord, signal cable, PGND wire, etc.) should be cabled and bundled separately rather than together in the cabinet. If they are close to each other, you can cable them in cross-shape. For parallel cabling, the space between power cord and signal cable should be no less than 30 mm (1.2 in);

The cable binding rack and cabling channel inside and outside the cabinet should be smooth and without sharp edges or tips;

The metal cable management hole should have a smooth and fully rounded surface or wear a insulating bush;

Use the right type of ties to bundle the cables. Do not bundle cables with joined ties. 3Com Corporation provides the following types of ties: 100 x 2.5

mm(3.9 in x 0.1 in), 150 x 3.6 mm (5.9 x 0.1 in), 300 x 3.6 mm (11.8 x 0.1 in),

530 x 9 mm (20.9 x 0.4 in), and 580 x 13 mm (22.8 x 0.5 in);

■Cut the extra parts of the ties neatly after bundling the cables, leaving no sharp or angular tips. See the following figure:
