Building backbone cabling – cabling that connects a Building Distributor to a Floor Distributor. Building Distributor – the Distributor in which building backbone and campus backbone cables terminate, cross-connect and inter-connect. Category 5e (Cat 5e) - AS/NZS 3080 standard Category 6 (Cat 6) – a cable standard for Gigabit Ethernet, backward compatible with Category 5/5e - AS/NZS 3080. Cat 6 is designed for Gigabit Ethernet, 250 MHz. This cable can carry up to 10 Gbps but only up to 50 metres. When used for 10/100/1000 mbps the maximum allowed length is 100 metres comprising 90 metres of horizontal run to the patch panel and 10 metres between the panel and device. Category 6A – a cable standard that has performance improvements around the elimination of alien crosstalk compared to Cat 6. Cat 6A is capable of carrying 10GBASE-T for distances up to 100 metres and is rated at 500 MHz. Certified Installer – Party or parties responsible for the supply, installation, testing and warrantying of cabling systems. Consolidation Point – Hardware providing interconnection between two installed horizontal cables. Floor Distributor – distributor in which the building backbone and horizontal cables terminate, cross-connect and inter-connect. Horizontal Cabling – cable connecting the floor distributor to a TO Intermediate Distribution Frame – Rack/Enclosure for interconnecting data & telecommunications cable between end user devices and a main distribution frame. Main Distribution Frame – PoE – Power supplied over Ethernet; typically refers to devices where dc power is delivered via twisted pair cabling on the unused pairs, up to 15.4W PoE+ - Provides up to 25.5 W of power over 2 cable pairs UPoE – Universal Power over Ethernet provides up to 60 W of power over all 4 pairs Rack/Enclosure – a lockable cabinet which houses equipment and cabling Structured Cabling – Structured cabling brings all communications systems back to centralised patch panels. Services connecting at a patch panel may include telephone, data, alarm systems, distributed audio or TV, CCTV etc. One cabling system supplies all. Structured cabling systems provide enormous flexibility and manageability. Services can be patched locally without the need of Telco input. (See Discrete Cabling below) Inormation Technology Services Department of Education 8 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Discrete cabling – where a separate cabling plan is used for each type of services. E.g. a telephone would plug into a wall socket that could not be used for any other service. Wireless WAN - used by DoE in areas where cabled services are poor or do not meet the Department’s needs. Wireless WAN is not something directed at users but a system between two wireless systems. A beam from one wireless is aimed directly at another usually by line of sight. WLAN – Used for connecting users to a Local Area Network using wireless. A series of Wireless Access Points (WAPs) are connected to the LAN in a given site and a user’s device connects to a WAP.

All visitors to a Department of Education site must report to Reception to sign in and are required to comply with all directions as given by the School/Site Manager. Accredited Installers and Contractors shall also: Report to the site contact for advice on local requirements for Workplace Health and Safety, eg site specific induction, emergency procedures (evacuation) and location of amenities Inform the site contact and/or DoE IT Project Manager of any high risk activities being conducted and the type and duration of work to be undertaken. Examples of high risk activities include trenching, working at heights and working near underground services; Ensure that all work activities are carried out safely; Restore the site to good working order (ie replace furniture, fittings, etc), remove all waste and clean up any debris generated by their work activities. For further Information please contact the Facility Services (Operations) at [email protected] Asbestos Register An Asbestos Register is kept in a central area at each site such as Reception - all contractors and maintenance workers MUST inspect the Asbestos Register before works commence. Expected Conduct All Contractor personnel attending sites for any purpose are to wear the designated Contractor uniform and carry approved identification at all times. In carrying out the services, the Contractor shall at all times be mindful of the needs of the occupants of the site and shall follow all directions given by the school/site manager. Any visitor is required to act courteously at all times. This includes no smoking; no consumption of alcohol or drugs on or in the vicinity of the site, no offensive language or behaving in a threatening or dishonest manner. Inormation Technology Services Department of Education 11 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Security A Working with Vulnerable People registration is mandatory, prior to commencement of duty, for contractors undertaking ongoing work in schools, LINCs and other Agency sites. Noise and disruption The contractor is not to undertake work which disrupts the normal conduit of business without giving the school/site manager reasonable time to respond and stipulate any conditions. The emphasis here is on both sides being reasonable. It may be necessary to arrange a more appropriate time to undertake the works. LAN SWITCHES DoE has standardized on Cisco communications infrastructure for its LAN implementations. For Schools Switches can be purchased through the ITS online shop. IT staff can provide advice around product suitability and recommendations to determine best ‘fit’. For Contractors/Installers Several Cisco switch models are currently available for purchase by the Agency. Technical specifications including dimensions can be obtained from Cisco’s website. Inormation Technology Services Department of Education 12 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS WIRELESS ACCESS POINTS (WAPS) For Schools The Agency uses an enterprise wireless network provided under the Networking Tasmania contract. WAPs can be purchased through the ITS online shop. IT staff can provide advice on the number and locations of WAPs for sites as well as lifecycle management. Schools need to discuss their WIFI requirements with their local IT support staff. For IT Staff Floorplans of coverage areas shall be submitted to Telstra by the ITS Networks Team, to enable WAPs to be managed via Cisco Prime. Site predictions should be undertaken in Prime to assist with proper placement of WAPs where coverage areas have obstacles which may impede signal strength and reach. For larger sites where required wireless coverage is more complex, Telstra can undertake an on-site physical survey at a cost to the School which can be negotiated via ITS. WAPs should be connected to PoE+ compatible switches. The ITS online shop provides further information on feature sets of current model WAPs and their requirements. It is recommended that WAPs not be connected to multiple power sources (eg a PoE+ switch and an injector) as this may cause the WAP and the upstream switch to shut down. In this instance 802.11ac enabled WAPs should continue to connect to standard PoE switches without the use of a power injector. The use of outdoor WAPS should be discussed with ITS as additional network and physical requirements are necessary to support this infrastructure. For Contractors/Installers Where new cabling is required for WAP installations it shall be a minimum of 2 x Cat6A runs. A labelled double outlet at the WAP end shall be provided - this will enable the WAP to be repositioned, if required, via the flexibility of a patch lead. Note that new cabling installations must be tested and installed by a Certified Installer. There shall be a minimum clearance of 30 cm from any surface of the WAP to nearby persons and where the WAP has integrated antennas it shall be mounted horizontally unless an appropriate bracketing system is used. It is recommended that access points and wireless network antennas be mounted in elevated positions, at or near typical ceiling height where possible. This is to enable ease of access (taking OH&S into account) and to minimize the potential for both radiation exposure and vandalism. Inormation Technology Services Department of Education 13 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS At a minimum where external WAPs are mounted on roof tops or other exposed locations (which may be subject to lightning strike) each antenna will require earthed lightning protection. Please refer to the list of Australian and International Standards referenced in this documentation together with the Manufacturer’s instructions as a minimum accepted standard for Wireless mounting standards within the Department. DATA AND GENERAL CABLING RULES Work performed by Contractors shall comply with all relevant Tasmanian Acts and Legislation. Where appropriate, and without introducing unnecessary duplication, the specifications and requirements within this document reference the Cabling Provider Rules, Regulatory Standards and Australian Standards which contractors are required to meet and/or comply with (Refer to tables in Appendix C). Note that these standards/specification may refer also to additional Australian and International Standards. These cabling installation notes are to be read in conjunction with any project Technical Specifications. Contractor Certificates and Obligations The Telecommunications Cabler Provider Rules, 2000 (CPRs) require that all telecommunications cabling be performed by registered cablers, and that all such cabling work shall comply with AS/ACMA S009:2013 (the Wiring Rules). A completed TCA-1 form must be provided for all cabling installations. A Certificate of Electrical Compliance form is required when new installations, alterations or additions to any electrical works are performed. Horizontal Cabling All horizontal cabling shall be Category 6A – this applies to new and existing installations. Cable and other cabling equipment installed for connection to a carrier’s telecommunications network shall be installed in accordance with the manufacturer’s instructions. Plastic cable ties must not be used under any circumstances. All surface/wall cabling shall be enclosed in compliant conduit. Cables must not be loosely bundled and laid in a random manner. Inormation Technology Services Department of Education 14 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Cabling must be fully supported by independent cable support systems and shall not be laid onto other services or ceiling surfaces. All cabling shall be secured to support structures via a hook and loop style cable ties (Velcro or similar). Cables must not be over tightened. If this occurs, the performance of the cable may be affected so that specifications cannot be met. Cables must be anchored immediately before and after a bend in a cable or loom. This ensures that the minimum cable bending radius is maintained. There shall be no more than 32 4-pair cables or equivalent in a loom, for Class D and below. For Class E and above and FTP, no more than 24 4-pair cables. These recommendations also apply to catenary wire support systems. Anchoring may not be required where cables are installed horizontally on a continuous support, such as a tray, where disturbance or possible damage is not likely. Horizontal Cabling at the Work Area All work area patch leads shall be selected and available in varying lengths such that the Horizontal cable length is within 100 metres. Telecommunications (Wall) Outlets As a minimum requirement double wall outlets shall be installed. This provides flexibility in the event of a cabling failure. Backbone and Inter Building Cabling Optical fibre cable must be used between buildings. The only exception is where buildings are connected via a wireless link. A minimum of 8 core OM4 Multimode cable which is capable of supporting 10GB Ethernet 850nm must be used as a minimum for all backbone and inter building cabling. The only exception to this is where the cable length exceeds the specified parameters in which case Single Mode cable shall be used. All fibre terminations will be LC. NOTE: All Optical Fibre Cabling Between buildings must be Indoor /Outdoor Rated Distribution style Cable. Inormation Technology Services Department of Education 15 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Labelling The wall outlet numbering will be in the format as follows: Rack Name Rack Unit (RU) Number/Patch Panel identifier Patch Panel Socket number e.g. Rack “A” Rack Unit (RU) “27” Socket 7 will be labelled as A-27-7. Telecommunications outlets must be labelled with the outlet number (which corresponds to its appearance at the distributor) and those additional identifiers which may be necessary to uniquely identify the outlet at the respective premises. Cross-connect positions for horizontal cabling must be labelled to correspond to the labelling of their respective telecommunications outlets. Distributor Cabinets, Racks or Frames Distributor cabinets, racks or frames must be fitted with a large label readily visible and legible from a range of at least 2 m showing the distributor identification. The sheath of backbone cables linking distributors must be labelled using a wrap on label or affixed tag at each end (distributor, splice point or underground joint) detailing the cable type, capacity, remote distributor and termination appearance and local distributor and termination appearance. Consolidation points Consolidation points must be fitted with a label indicating the maximum cable run length from the consolidation point to a connected telecommunications outlet. Multiuser telecommunication outlets must be fitted with a label indicating the maximum fly lead length which may be used to connect to terminal equipment. Fibre Optic Patch Fields Fibre optic patch fields must be labelled with laser source warning signs to AS/NZS 2211. Where mixed multimode fibre core sizes are used on the same site (for example 62.5/125µm and 50/125µm), a means of distinguishing the core size must be provided at the connector and on patch cords to prevent mismatched fibres from inadvertently being patched. Labels must be of a size, colour and contrast to be readily legible and have a useful life equal to or greater than that of the component being labelled. Machine printing or engraving with a minimum text size of 10 point (or 2.5 mm text height) is recommended for outlets and distributor appearances. Distributor identifiers should be highly visible and have a minimum text height of 10 mm. Inormation Technology Services Department of Education 16 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Testing and Test Results General All cabling must be tested. This includes all newly installed cabling and any cabling that has been re-terminated or re-arranged. Any cabling which fails to pass testing shall be replaced at the Contractor’s cost and re-tested. All cabling test results must be presented as delivered by the testing device in an electronic format such as Linkware and also in PDF format. Testing will meet the requirements of the latest revisions of the below standards: AS/NZS IEC 61935.1 (in accordance with values set out in AS/NZS 3080) Testing of balanced communications cabling IEC 14763.3 - Testing of optical fibre UTP (Copper) Cabling Tests All cable runs are to be testing for continuity and polarity (wire map). Testing parameters and results shall include as a minimum: Near-end Crosstalk (NEXT) Loss – bi-directional Far-End Cross Talk (FEXT) – bi-directional Attention to Crosstalk Ratio Far-End (ACR-F) Attenuation to Crosstalk Ration Near-End (ACR-N) Power Sum Crosstalk Insertion Loss Return Loss Propagation Delay – bi-directional Delay Skew Wire Map Optical Fibre Cabling Tests An approved fibre cable scanner shall be used for all testing. Testing shall include the following as a minimum: Results are to reflect loss, length, fibre identification and the number and type of connectors and splices used Expected loss budget calculation results (as a direct comparison to the actual test results) All multimode fibre links shall be tested bi-directionally with an Optical Loss Test or approved fibre cable scanner at both 850 nm and 1300nm wavelengths Inormation Technology Services Department of Education 17 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS All singlemode fibre links shall be tested bi-directionally with an Optical Loss Test or approved fibre cable scanner at both 1310 nm and 1550nm wavelengths Where any fibre optic cable length exceeds 300 metres, fibre tests shall include OTDR testing in both directions WAN Services into DoE Sites DoE Wide Area Network (WAN) services are provided by various Service Providers under the Networking Tasmania Contract. At the time of writing the services DoE purchase from Networking Tasmania III are supplied by Telstra, iiNet, TasNetworks and Tasmanet. Networking Tasmania provides DoE with a port(s) on site into which the Local Area Network connects. VOICE OVER IP (VOIP) VOIP is a method of using the data network and Internet Protocols (IP) to carry telephony services. This can be done using a local VOIP switch with several external lines or it could be done via the WAN to a central server in a remote site. The choice of solution is based on cost, functionality, serviceability. Whole of Government has gone through a tender selection process for Small Site VOIP solutions. The successful tenderers are listed below: MyNetFone SSIT: Contact: Tony Poulson Email: [email protected] Ph: 03 8488 7677 Samsung SSIT: Contact: Craig Snowden Email: [email protected] Ph: 0413441995 Cisco / Modern Comms: Contact: Log a request via the Department of Education ITS Helpdesk http://help.education.tas.gov.au All VOIP solutions must be provided by either of the two successful tenderers. The School Consultant must be notified and involved in the selection process of any VOIP solution. Inormation Technology Services Department of Education 18 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS OUTDOOR WIRELESS BRIDGE INSTALLATIONS When connecting buildings via Wireless Bridges, the Manufacturer’s Guidelines must be followed and consideration given to adequate lightening protection and the appropriate positioning of radio and antenna equipment. COMMUNICATIONS RACKS, CABINETS AND ENCLOSURES Overview Communications cabinets and/or enclosures have a requirement to house racks that may comprise patch panels, cable management, switching equipment, servers, UPS, security systems, etc. It is therefore vital that racks, cabinets and enclosures are chosen with this functionality in mind. A typical rack layout is depicted in Appendix A. Note the following minimum requirements for green field sites and new rack installations: When planning for new rack deployment ensure an additional 30 – 40% of RU space is free for future growth Racks exceeding 18RU in size must be floor mounted Where running PoE or PoE+ the bundle size is limited to up to 40 cables per bundle due to heat dissipation. This must be strictly adhered to where small diameter patch leads are used in a PoE environment. Safety of Installation In the performance of any cabling work, in general the cabling provider should ensure that— End-users are protected from personal electrical contact with any voltage/service other than SELV and from any exposure to laser radiation; Cabling providers are protected from accidental personal electrical contact with LV telecommunications circuits, LV power and HV circuits or accidental exposure to hazardous laser radiation; Inormation Technology Services Department of Education 19 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Cabling providers who are required to access, install or maintain LV telecommunications circuits, are protected from accidental personal electrical contact with LV power and HV circuits; Licensed electrical workers are protected from accidental personal electrical contact with any telecommunications circuits or accidental exposure to hazardous laser radiation; and The creation of any general safety hazard is avoided, e.g. tripping, falling or bodily impact with a protruding object. Note: end-users are all persons other than persons performing cabling work, including persons who do not actually use the telecommunications service (e.g. casual visitors, cleaners). End-user contact with SELV circuits should be prevented where practicable. Note: Provision is made in this Standard for cabling providers who are suitably qualified or licensed to access LV telecommunications circuits, LV power or HV circuits. Cabling providers must comply with relevant Commonwealth, State and Territory OH&S requirements including, but not limited to, Building Code requirements. Cooling and Airflow Requirements All server racks are to be fitted with front mesh doors (and rear where possible) and fans installed to the roof of the server rack to allow for adequate air flow, ventilation and heat dissipation. Security For the purpose of this document, an ‘enclosure’ includes a closet or room provided for the express purpose of housing the MDF, in which case the closet/room door is to have provision for securing with a key, lock or tool if the MDF doesn’t. Note The building owner, manager or occupant is responsible for the security of the MDF. The MDF should be adequately secured against vandalism and access unauthorised persons but reasonable access should be given to carriers, carriage service providers, cabling providers and other authorized personnel as required. All racks must have lockable doors and removable and lockable sides. Ladder racks or open racks may be installed to lockable rooms that do not have general access to ensure adequate security. Inormation Technology Services Department of Education 20 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Positioning of enclosures/cabinets and racks In order to avoid the need for ladder access to racks as a guide racks should be positioned no higher than 2 metres to the top of the rack from the floor. The lowest terminal or socket should not be less than 350 mm above finished ground or floor level. Specifying Racks & Cabinets Refer to Appendix B for further information on rack categories. Wall Mounted Racks Wall mounted racks used by the Agency have a maximum depth of approx. 700 mm (600mm rack + 100mm hinge). Wall mounted racks are available in 6, 12 & 18 RU. Racks which are larger than 18RU must not be wall mounted under any circumstances. Floor Mounted Racks Floor mounted racks come in two size categories – full height or half height. Full height racks are 42-45RU in size with an approximate depth of 1000mm. Full height racks may contain core switch equipment, servers and UPS together with other equipment. Full height racks may also contain network infrastructure only without servers. These are sometimes referred to as communications or network cabinets. Half height racks used by the Agency are generally 22-27RU in size with two depth categories these being approx. 1000mm and 800 mm. Server racks should be approx.1000mm deep while half height communications racks may be 800mm deep. Compact Enclosures At times it may be necessary to use compact enclosures where a horizontally flush mounted cabinet is required. In this case, a Panzone PZAEWM3 or equivalent must be used. These enclosures offer 6RU – 3RU for inactive equipment, i.e. patch panels and 3RU for active equipment, i.e. switches. Note that these enclosures must be lockable. Inormation Technology Services Department of Education 21 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Consolidation Points Consolidation Points (CP's) may be used in special circumstances, eg to re-locate a rack to a more suitable location. There shall be no more than 1 CP installed per horizontal cable run. Note that Consolidation Points: must be an in area that is easily accessible for fault finding must be within the 90 metre range for test limits must be installed in a manner that has the capacity to be secured and locked Cable Management For racks where horizontal cable count exceeds 200, a DoE designed rack layout is required. In large racks (24 RU and over) or exceeding a horizontal cable count of 200 vertical cable management rings must be large enough to cope with the patch cabling to be run. As a rule of thumb allow for 2 patch cables per user in office areas and 2 per user in classroom environments (this should provide enough spare capacity to allow free movement in the vertical). In smaller racks (less than 24 RU) the use of Velcro straps for vertical cable management is acceptable. Vertically mounted enclosures may be used where 3 or less patch panels and only 1 or 2 switches are required. This type of enclosure mounts the switches vertically and provides a much more efficient use of wall space. Note: Plastic or metal cable ties must not be used to tidy patch cables under any circumstances. Patch Panels 24 way patch panels per 1 RU with fully populated sockets are to be used in all DoE racks. Patch panels shall be provided with integrated rear cable management units so as to provide cabling support. Where this is not possible then an alternative form of cable support should be provided. Refer to Appendix A for cable management and layout specifications. There is now available a new small diameter patch cable offering which utilizes 28 AWG conductors. This allows for higher density installations and better cable management, improved air flow, flexibility and a tighter bend radius of 15mm. It is recommended where possible that small diameter patch leads are used throughout rack installations. Inormation Technology Services Department of Education 22 DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS Different patch lead colours shall be used to differentiate DoE telecommunications services according to the DoE Patch Lead Colour Code (refer Appendix B – Patch Lead Colour Code chart). Power to Racks and Patch Cabinets All power is to be contained within the inside of the data rack. All protective earthing is to be of 6mm cable size. All electrical work must be undertaken by a licensed practitioner. It is mandatory by law to RCD protect any new power circuits installed on any premises that allows an individual to plug in an appliance (refer RCD Protection – AS3000) UPS To calculate UPS requirements, formula is as follows: Volts x Current x Number of Appliances x 1.2 = VA Edge Switch and Non Critical Racks Edge Switch and Non Critical Racks will consist of a front mounted 5-8 way horizontal power rail to be fitted. A capture plug may need to be installed to prevent dislodgement from power source. Server and Core Power requirements consist of a 10-22 way vertical power rail in conjunction with a 15 amp dedicated power circuit with UPS backup. Earthing of Cabinets All racks, cabinets, cable trays and catenary wires must be connected to the building protective earth as specified for each case in AS3000 and AS/ACIF S009 (latest revision;. this includes earthing of lightening devices.
