Figure 67 Cable binding example 3
The spare cables or excessive cable parts should be folded and bound and placed at a right place
•
in the rack or on the cable routing slot. A "right place" refers to the place where the cables will not
affect the operation of the switch or impair the switch, or be damaged.
• The power cords cannot be tied on the slide rails of any mobile components.
Reserve some redundancy for the cables connecting to the mobile parts, the PGND cable of the
•
door for example, to free the cables from possible stress. Such a mobile part should be installed in
such a way that the extra cable segments will not contact the heat source, sharp points, or edges.
Use high temperature cables against the heat sources.
• For the cable terminals fixed using screw threads, the screws or nuts should be securely fastened
and prevented from loosing. See the following figure:

organized.
The following table lists the requirements in the binding with cable ties.
