As recommended by the IEEE 422 Standard, cable from redundant machines and redundant wires should be routed in distinct routes.
Also, one unit’s wires must be separated from the other unit’s. Cable routing should be performed to ensure that at least half of the unit’s critical disks and inter-unit auxiliaries are secure in the event of a fire (not impacted by a single fire).
Other points to be considered include:
- Cables should be placed in strict accordance with the timetable of the prepared cable.
- All wires must have identification tags on both ends, wall or ground crossing on both sides, tray or trench at periodic intervals, etc.
- All trays and
subtraysmust be numbered at regular intervals.
- No jointing of cables for <250 m
- Buried wires should be shielded at 20 m gaps and at bends by concrete slabs with road markings.
- Road-crossing wires must pass through PCC-buried high-density polyethylene (HDPE) and appropriate clearance must be retained with other electrical LV and MV wires as approved by the owner (not < 1 ft).
- All wires should be placed in the trays neatly and
clamped / tied. Fiber optic wires should be inside and, whenever possible, can be put inside cable trays.
- The cable pulling tension and cable bends recommendation of the cable manufacturer must be followed during installation to prevent damage to the cable.
- Some accessories should be used for secure
cabling, such as a surge suppressor, opto-isolatorand fiber optic card cage, as well as a set of terminating kits such as a crimping instrument.
- It seems to be simple to terminate twisted pair wires, but some experience is needed to do the work. It is very essential to cut a correct cable length for termination to have sufficient margin for connecting connectors, leaving excess cable at the termination stage.
- The quantity of cable to be subjected to RJ45 connectors for wires such as UTP is typically 1. ‘ It should be prevented over twisting. The original termination testing after installation is
of the installer’s work. component
- Fiber optic cables in networking
isbecoming increasingly important.
- The installer should be well trained in the basics of fiber optic cable installation, and workmanship in this situation is highly essential for network performance.
