General Cable Routing Principles
To avoid loss resulting from incorrect cable routing, follow specified principles when routing ground cables, power cables, network cables, mini SAS cables, serial cables, and optical fibers.
General Cable Routing Principles
- In an equipment room containing brackets and an ESD floor, cables can be routed through the ground interlayer (the space between the concrete floor and the ESD floor) or the cable tray. Also, cables can be routed through a cable tray that is installed on the top of the cabinet.
- The specifications, routing, cross-section, and location for cable routing should be predetermined, and the cables should be arranged neatly.
- The insulation layer of the conductor should be intact.
- Cables must be bent smoothly with a bend radius of larger than 60 mm.
- Ease of maintenance and expansion should be considered when routing cables.
- Power cables and ground cables should be separated from signal cables to reduce electromagnetic interference.
General Optical Fiber Routing Principles
- Do not forcibly pull or excessively bend the optical fibers.
- The bending radius of optical fibers must be no less than 50 mm.
- Do not stack other cables on the laid optical fibers.
- When used in a cabinet, optical fibers should be inside corrugated pipes. The corrugated pipes should be stretched into the cabinet by about 100 mm.
- Cut the corrugated pipe according to the required length during hardware installation. Wrap tape around the sharp edge of the corrugated pipe to protect the optical fibers.
- In an equipment room containing brackets and an ESD floor, optical fibers shielded in the corrugated pipes can be routed through the ground interlayer or the cable tray.
- Optical fibers can be routed through the cable tray installed on the top of the cabinet.
- If the cable tray is more than 0.8 m above the cabinet top, set up a cable ladder above the cabinet.
