Appendix B Cabling recommendations
Routing cables
The cable management brackets are installed on the two sides of the service module section. As a
best practice, route cables from the left and right sides of the device, as shown in
Figure 8-1 Routing cables (S12516G-EF)
Routing power cords
When you route power cords, take consideration of the layout of the equipment room, including the
locations of the power distribution cabinet, AC power receptacles, and lightning protection box. Place
all re-connecting facilities, such as receptacles, at the rack bottom (Do not place them at a location
out of the rack and easy to reach.)
The power modules are located at the left and right sides of the rear panel. As a best practice, route
power cords from the left and right sides of the rear panel.
General cabling requirements
Minimum curvature radius of cables
•
The curvature radius of an attached power cord, communication cable, or ribbon cable should
be a minimum of five times the cable's outer diameter. If the cable is frequently bent, plugged
and unplugged, the curvature radius should be a minimum of seven times the cable's outer
diameter.
