Installation planning outline and checklist It is recommended that you follow this installation planning outline as a guide when planning a cabling system. Determine the scope of the cabling system installation. Building size (square meter or square feet) Number of people - Number of work areas - Number of phones per work area - Number of terminals per work area Functional areas affected - Building maintenance department - Contractors Review building plans for suitability and adaptability. Number of floors Number of data cabinets available - Combined phone and data closets - Separate phone and data closets Wiring location - Ability to communicate with other areas of the building during problem determination Environmental suitability - Temperature/humidity - Dust - Gases - Cable requirements Grounding - Structure, power, signal, piping, lightning protection, ground shift potential, and current Cabling passageways/channels - Location - Accessibility - Dimensions - Coordination with other systems Freedom from electrical environment contaminants - Radiated frequency interference (RFI) - Induced electromagnetic interference (EMI) - Electrostatic discharge interference (ESD) - Low-frequency interference (LFI) Document terminal inventory. Machine type - Model - Quantity - Services for each machine type - Relevant special features - Devices supported by cabling system - Devices that could migrate to the cabling system (for example, typewriters to office system). Document logical network configuration. Document data flow between machines. Document related software systems (MVS, DOS/VS, VM, and others) and subsystems (CICS, IMS, VTAM, NCP) as required for problem determination. Document physical network topology. Obtain building floor plans. Develop or use existing coordinate matrix system so that each work area or data cabinet can be uniquely identified by its coordinates. Draw a wiring diagram superimposed over the floor plans. - Indicate vertical cable runs - Indicate loca
