9.1 Signal Cable Installation Requirements
Cabling Principles
l
Before installation, signal cables must pass the continuity test. Both sides of each
signal cable should be marked or labeled correctly.
l
Signal cables must be free of damage, breakage, and joints.
l
Do not route signal cables on ventilation holes because this will affect heat dissipation
and cable life.
l
During the cabling, it is not allowed to bind power cables and signal cables together.
l
Cabling in the cabinet must not affect door installation.
l
Cables must be routed along the horizontal and vertical cable trays in a flat and straight
manner, without crossovers or folds.
l
For a small number of optical fibers, the fibers can be routed together with other cables
and protected in soft management sets. For a great number of optical fibers, the fibers
should be routed along vertical cable trays and protected in sylphon bellows.
Binding Principles
l
Cables should be bound with appropriate force and tightened properly. Cable ties
should be arranged in the same direction.
l
The surplus part of the cable tie should be cut off from the root without any jagged
edge.
l
Take protective measures when attaching a signal cable to a sharp structural
component.
l
Optical fibers should be bound with the optical fiber ties for protection.
