Precautions for Assembly
Use dedicated tools or tools delivered by Huawei and follow the methods given here
during assembly.
Hold terminals of cables instead of pulling the cables themselves when installing or
removing cable components.
Take the following precautions when cutting or stripping cables:
− Make cables slightly longer than necessary.
− Coil cables longer than 2 m (6.56 ft) after cutting. Bind and fasten the coils using
bundling ropes. The inner diameters of the coils should be larger than 20 times the
outer diameters of the cables.
− When stripping the jackets of cables, avoid damaging the shield layers (braid or
aluminum foil), insulation, core conductors, and other jackets that do not need to be
stripped.
− After assembling cables, cut all visible cross sections of jackets to ensure that the
cross sections are arranged neatly.
− Do not touch the core conductors of cables with your hands. Terminate exposed
conductors in a timely way after stripping off insulation so that the surface of the
conductors does not become oxidized.
Take the following precautions when crimping and connecting cables or connectors:
− The terminals and conductors should be connected tightly after they are crimped.
They should not be moved or turned.
− Cut all the exposed copper wires.
− Try to avoid a second crimping of sleeves.
− Keep all the conductors clean and aligned.
The connectors, cables, and tools provided by different vendors may be different. The figures in this
document are for your reference only.
