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:
