Figure 52   Cable bundling example I

■

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:
