Figure 54 Correct and incorrect cable binding
The cable bend radius at connectors must be a minimum of 5 times the cable diameter, and must
•
be a minimum of twice the cable diameter away from the connectors.
Route different types of cables separately (for example, power cords and signal cables). If they are
•
close to one another, cross them over one another. If you route them in parallel, make sure the space
between a power cord bundle and a signal cable bundle is a minimum of 30 mm (1.18 in).
Make sure the cable management brackets and cable routing slots, inside or outside the rack, are
•
smooth and have no sharp edges or tips.
• When you route cables through sharp sheet metal penetration points or along sharp edges of
mechanical parts, use bushings or take any other action to protect the cables from being cut or
abraded. The sheet metal penetration points must be smooth and fully rounded.
Use the correct type of ties to bind the cables. Do not bind cables with joined ties. The following
•
types of ties are available: 100 × 2.5 mm (3.94 × 0.10 in), 150 × 3.6 mm (5.91 × 0.14 in), 300 ×
3.6 mm (1 1.81 × 0.14 in), 530 × 9 mm (20.87 × 0.35 in), and 580 × 13 mm (22.83 × 0.51 in).
After binding the cables, cut the excess from the ties, leaving no sharp or angular tips. See
•
55.
Figure 55 Cutting cable ties
When you bend cables, bind them as shown in
•
core break, do not tie up the cables in the bending area.
