Appendix F Cable management

Label cables before you route or bundle them. For more information about labeling cables, see
"Appendix E Engineering labels for cables."
Cable management guidelines
When you route and bundle up cables, follow these guidelines:
• Bind cables neatly for easy maintenance and expansion.
The cable management brackets and cable routing slots, inside or outside the rack, are smooth and
•
have no sharp edges or tips.
Route different types of cables (for example, power cords 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 cord bundle and a signal cable bundle is at least 30 mm (1.18 in).
Use the correct ties to bind the cables. Do not bind cables with joined ties.
•
The distances between cable ties must be three to four times the cable diameter.
•
• Bind and route the cables neatly inside the rack, and make sure the cables are not kinked or bent.
Do not tie cables or bundles in a knot.
Figure 97 Correct and incorrect cable binding
When you bend cables, bind cables as shown in
•
excessive stress, do not tie up the cables in the bending area. The cable bend radius at connectors
must be at least 5 times the cable diameter, and must be at least twice the cable diameter away
from the connectors.
