SayPro Creating Design that meets user requirements

Description

v Plan and design the cable layout
– Cabling plays an important part of network design as it provides the physical communication path

v Create a spread sheet to gather key details needed for the design
– Information collected must include the number of users per location, their roles, LAN port speeds and node types, such as printers and any hardware that will be connected to the network. Other network requirements include programmable logic controllers for robotics or other automated systems requiring network connectivity. Configure the spread sheet by listing physical locations across the top columns and creating row categories for users.

v List the total number of users per site and classification type
– identify each server and the applications hosted, as well as operating systems and network card speeds. Also document the computer room’s environmental services for air conditioning, electrical capacity and controls to monitor humidity and temperature levels.

v Analyse network performance in its current state.
– This activity provides information associated with LAN and WAN performance, protocols used and areas in the existing topology that create performance bottlenecks along with application characteristics.

Collect your existing physical and logical network diagrams to support the current state design
-Document protocols used in the network, including routing protocols used for connectivity between buildings

v Determine the number of LAN switch ports required currently and projected
-The telecommunication closets provide copper network cables to each employee’s desk if the distance from the computer room exceeds cable limits

v Select access layer switches based on your projected growth requirements for network ports and future expectations
-lan enough strands of fibre between the access layer and the computer room switches for growth as well as ensuring that the fibre uplinks and switch ports will support bandwidth requirements.

v Select switches and routers, introducing standards for each layer of the network
-Network switches and routers must support immediate port requirements and have the ability to expand when new features are introduced

v Select computer room switches.
-Plan the port density and speeds to support the servers in a combined distribution and core layer

To obtain the reliable high performance design targets for an installed data cable system, various factors need to be controlled.

1. Materials Selection – The cables, connectors, and terminals used shall meet adequate technical specifications. All the hardware shall be manufactured under a certified Quality Management System (QMS) such as ISO 9000.

2. Engineering Plans – Detailed engineering plans, drawings and general directions including specifying the best or first choice cable path shall be provided for installation.

3. Installation Practices – Minimize physical stress and damage to cable by decreasing exposure of cables, components and individual conductors to kinking, abrasion, twisting, bending and compression.

4. Worker Training – Equip and train installers with adequate knowledge, good M&P (methods and procedures), and the correct tools that are maintained in good working order.

5. Safety – Follow sound safety methods and procedures for both personal safety and protection of equipment.

6. Quality Assurance (QA) – Follow sound QA strategies that include network testing during all phases of the work.
