(50.6 mm): indicates that the distance between the installation plane of power subrack mounting ear and
the front of the subrack is about 50.6 mm.
Ensure that cables are more than 20 mm away from heat sources to prevent damage
(melting, aging, or breakage) to the cable insulation layer.
Ensure that the bending radius of each cable is at least five times the diameter of the
cable.
Bind cables of the same type together. When routing cables of different types, ensure that
they are at least 30 mm away from each other.
Route and bind cables so that they appear neat and tidy and their cable sheaths are intact.
