Figure 69 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 cables 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 near 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:

• When using a hard power cable, fix it near its terminal to free the terminal and the cable from
stress.
• Do not use tapping screws to fasten the connecting terminals.
• The power cable of the same type and in the same direction should be bound together and kept
organized.
• The following table lists the requirements in the binding with cable ties.
