Cable management guidelines
When you route and bundle up cables, follow these guidelines:
• Bind and route the cables neatly inside the rack, and make sure the cables are not kinked or bent.
Figure 128 Correct and incorrect cable binding
• Route different types of cables (for example, power cables, and signal cables) separately. 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 cable bundle and a signal cable bundle is at least 30 mm (1.18 in).
• 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 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
(11.81 × 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 Figure
129 .
