Cable management
Label cables before you route or bundle them. For more information about labeling cables, see "
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 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).
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 74 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.
