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.

•
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.
