For installation of cabling in accordance with lSO/IEC 11801-2, lSO/IEC 11801-3, ISOIIEC 11801-4 and lSO/IEC 11801-6, the planning, installation and administration requirements of Category RP3 shall be applied.
The capacity of the power supply or supplies to spaces from which remote powering is distributed shall be consistent with the stated objectives and power dissipated from the cabling should be included in the heat load calculation of the environmental control system of the building.
The technical specification shall detail the
• locations where less than the available number of cable elements are terminated at a termination point or joint,
• pin-pair assignment for balanced cable elements at interfaces to the installed cabling,
Annex A provides information about possible connections between the wires and the pins of telecommunications outlets within generic cabling systems in accordance with the referenced cabling design document. The same set of pin-pair combination should be used throughout the whole cabling installation.
• positioning of optical fibres at interfaces to the installed cabling.
NOTE Annex A contains requirements and recommendations for the maintenance of polarity within cabling terminated with connecting hardware housing multiple optical fibres.
When two cabling links of different specifications, but which are physically similar, are used in the same installation (for example, different performance Categories and cables with different nominal impedance), special precautions are required to ensure that they are properly identified.
The technical specification shall contain the requirements for
• the pathways, pathway systems, spaces, cabinets, frames, racks, closures, cables, termination points and cords (see Clause 7),
• differentiation of pathway systems and cables associated with cabling subsystems installed to provide enhanced reliability within the infrastructure (e.g. tie cabling),
• the bonding of the cabling components to the protective and functional earthing systems (see IEC 60364 series and ISO/IEC 30129).
Spaces, pathways and/or the pathway systems within the pathways shall be able to accommodate components and where necessary provide adequate ventilation, in order that any stated remote powering objectives neither compromise the transmission requirements of the installation specification or the warranty conditions of the components.
