TRAINING
Data Center
Cabling System
This training addresses all the issues generated by the complexity of IT cabling in buildings and data centers, and allows you to prepare for any new project or renovation. It addresses copper and fiber optic infrastructures, the different architectures as well as performance levels.
Prerequisites
This training requires a basic technical knowledge in cabling and computer network equipment.
Goals
This training responds to all the issues generated by the apparent complexity of building and data center infrastructures, and allows you to prepare for any new construction, renovation, or operation, with the main objectives being sustainability, availability and guaranteed high bandwidth and support for high-speed applications up to 400 Gbps and beyond.
Program
Building and data center topology: backbones and campus, horizontal distribution, patching, interconnection, color coding. Behavior on fire: flame propagation, smoke release, toxicity. The impact of the computer cabling system on the thermal management of computer rooms: overhead cabling, cabling in the raised floor plenum, organization of cabling in computer cabinets. Smart patching.
Copper Cabling
The points covered for copper are:
