1 Purpose

This Design Guide provides the Architect/Engineer (A/E) community with the necessary criteria to assist in the systems design of enterprise network requirements that are typically found in a Department of Defense Education Activity (DoDEA) education facility. While certain features of the systems design and network requirements will vary from project to project, the requirements reflected within this document are intended to capture the minimum requirements needed to meet DoDEA design standards.

Furthermore, this document provides information about specific DoDEA network requirements. A separate Special Systems Guide accompanies this guide, which captures details for additional special systems, including low voltage systems.

2 Applicability

Information in this guide applies to DoDEA, and Construction Agents having DoDEA Military Construction (MILCON) responsibilities to include US Army Corps of Engineers (USACE), Naval Facilities Command (NAVFAC), and the Air Force Civil Engineer Center (AFCEC), as well as Architect/Engineer (design) firms, and construction contractors. These instructions are intended to be used for DoDEA MILCON school replacement projects or projects that are extensively modifying existing facilities.

For all new or modified DoDEA facilities, the designer/construction contractor must demonstrate that the criteria outlined in this and other relevant guides for each technology system have been met. Host nation funded projects should comply with this guideline to the greatest extent possible. After standard warranty periods have expired, any modifications to host nation funded facilities must comply with the criteria outlined in this guide.

If there are discrepancies between any standards or regulations, the DoDEA Design Guide will be utilized for resolution. If no solution is listed in the guide, then the most stringent industry standard is applied and must be added to the project as a reference. This also applies to all trades.

4 Roles and Responsibilities

4.1 Headquarters, Department of Defense Education Activity

DoDEA Headquarters (HQ) is responsible for program management by providing scope, direction, funding and financial management of the entire DoDEA Military Construction (MILCON) design and construction program. The DoDEA HQ Facilities Branch, through the DoDEA Facilities Regional Project Manager (PM), is responsible for ensuring that design submittals for DoDEA projects are routed through the Information Technology (IT) Division’s Infrastructure Program (IP) Branch MILCON review team. This team provides timely feedback regarding design submittals to ensure compliance with this guide and other relevant standards, along with comments or recommendations for project implementation.

Other DoDEA Divisions, such as, but not limited to, the Security Management, Safety and Occupational Health, Logistics, Facilities, or Education, must also provide guidance where their areas of responsibility intersect with technology system requirements.

4.2 Department of Defense Education Activity Region Offices – Regional Project Manager

The DoDEA Region Offices (Americas, Europe, and Pacific) must provide a PM to coordinate with the School Superintendent, local Logistics staff, and host installation representatives to capture local technology requirements. For the purposes of this document, the Facilities Engineer for a project is referred to as the DoDEA Regional PM. He/she must coordinate with DoDEA HQ staff, the IT IP MILCON review team, Region Facilities and IT representatives, the DoDEA Design Center, and the Construction Agent Project Manager to ensure that the A/E and construction contractor implements the latest DoDEA standards for DoDEA network and special systems within each project. The DoDEA Regional PM must initiate coordination with IT IP at the planning stage of each project, with detailed reviews beginning at the 35% stage.

4.3 Facilities

DoDEA Facilities personnel are required to do the following:

• Provide a compact disk (CD) and copies of drawings with specifications during reviews.

• The Norfolk District Technical Manager (TM) supports DoDEA HQ, the DoDEA Regional PM, the DoD Construction Agent (DCA), and the A/E as a technical Subject Matter Expert (SME).

4.4 Host Installation

The host installation and supporting agencies, such as the Network Enterprise Center (NEC) on Army installations, are responsible for working with the DoDEA Regional PM to ensure projects satisfactorily incorporate local technology requirements. The installation must further provide relevant information regarding local telecommunication facilities, network infrastructure, and distribution systems, as well as identify the location and capacity of existing available fiber optic/copper cables in the proximity of a project and provide technical support as needed during design and construction activities until project completion.

4.5 Department of Defense Construction Agent – Project Manager

The United States Army Corps of Engineers (USACE), Naval Facilities Command (NAVFAC), and Air Force Civil Engineering Center (AFCEC) are assigned design and construction execution responsibilities associated with the MILCON program. The DCA executes all design and construction contracts within their area of responsibility. The DCA PM, in concert with the DoDEA Regional PM and the Norfolk District - DoDEA Design Center, must ensure that the A/E and construction contractor implement the latest DoDEA standards throughout each DoDEA project.

4.6 Norfolk District Design Center – Technical Manager

The USACE Norfolk District serves as the Design Center for DoDEA. The primary role of the Design Center is acquisition of design services through an Indefinite Delivery/Indefinite Quantity (ID/IQ) specifically for the design of DoDEA schools. The Design Center Technical Manager (TM) serves as the Contracting Officer’s Representative (COR) on the A/E services contracts. The Design Center supports DoDEA HQ, the DoDEA Regional PM, and the DCA PM on the technical execution of DoDEA specific requirements. The Design Center TM will ensure that the A/E is aware of the design requirements and submits the proper documentation for review at each submittal.

4.7 Architect/Engineer Designer and Construction Contractor

The A/E designer is responsible for producing the construction documents, which include both drawings and specifications. The design analysis is not part of the construction documents but is used to document background rationale and decisions made during design. The design analysis is a tool used during design by the delivery team. The construction documents (plans and specs) are the basis for the MILCON contract. The construction documents must follow Federal Acquisition Regulations (FAR) and cannot include proprietary information. The Unified Facilities Guide Specifications (UFGS) are the template for the construction specifications and will be tailored to specific project requirements. The design must demonstrate that the criteria outlined in this and other relevant guides for each technology system have been met.

The construction contractor must follow the construction documents (plans and specs) in the execution of the MILCON contract. Any changes from the construction documents could result in a construction modification. It is very important that criteria are included during design because it is much more difficult to implement changes during construction. Technology changes more rapidly than many other building systems, but if a modification is required during construction there will likely be funding and schedule impacts that must be evaluated.

5 Data and Telecommunications System Summary

This section describes the data and telecommunications systems design, as well as installation and testing requirements. The design requirements are intended to provide uniformity of symbols, equipment layouts, cabling methods, pathways, drawing submittal requirements, and specification requirements.

In general, MILCON funding can only be used for “real property” or things that are integral to the building. All the infrastructure, including wiring, telecommunications racks, conduit, cable trays, terminations, and outlets are MILCON funded. A few systems such as the fire alarm, mass notification, PA/Clock/Bell, Security Intercom (AIPhone), and portions of the electronic Physical Access Control System (ePACS) will be funded with MILCON. Other equipment, including rack switches, surge protectors, controllers, and head-end equipment are considered “personal property” and must be Operations and Maintenance (O&M) or Procurement funded.

The MILCON contract will include infrastructure for both wired and wireless data systems installed and tested by a qualified contractor experienced in cabling installations. All designs must be in accordance with Building Industry Consulting Services, International (BICSI). The cabling system must be designed by a Registered Communication Distribution Designer (RCDD). The specifications shall call for installation in accordance with the Telecommunications Industry Association (TIA), Electronic Industry Alliance (EIA) General Guidelines, and the National Electrical Code (NEC). A copy of the designer/installer contractor’s current BICSI certifications must be provided for review. In accordance with the Unified Facilities Guide Specifications (UFGS), the installer/technician must have experience on at least 2 projects of similar scope, including experience in application, installation, and testing of specified systems. These guidelines must be coordinated as a supplement with the Education Specifications (Ed Specs). The A/E must include in the design analysis of all projects a list of active components and a pull schedule, as indicated in this guide, to be furnished via the DoDEA Regional PM to the appropriate DoDEA HQ IT IP staff to facilitate planning. This active equipment must be furnished and installed by the Government; however, the schedule must be developed by the design team.

Government furnished and government installed equipment (GFGI) is noted in this Design Guide.

If a community has Voice over Internet Protocol (VoIP) capability, the standards of that community must be followed. See Section 10 of DoDEA’s Special Systems IT Design Guidelines if VoIP is not available within the community or for additional guidance on copper cabling.

IT systems must consist of the following:

1. Incoming fiber optic and copper cables from the community telecommunication demarcation building to the main Telecommunications Room 1 (TR1).

2. TR1 housing the main network equipment rack.

3. Secondary Telecommunications Rooms (TR2, TR3, etc.) housing network distribution equipment racks as needed.

4. Fiber optic and copper distribution cables from TR1 to each secondary TR in a star topology, with copper distribution cable for voice.

5. Cable trays, conduits, and supporting devices for fiber optic and copper work area cables, with copper distribution cable for voice.

6. Category (CAT) 6 copper cables from the distribution rack patch panels to individual work area outlets.

7. Work area outlets consisting of work area connectors, faceplates, room identification, patch panel, and ports serving each connector.

8. All IT and special systems, both software and hardware, installed, intended to be procured as

Furniture, Fixtures, and Equipment (FF&E), or otherwise used in DoDEA schools must have prior approval and are subject to DoD security provisions. Prior approval is required for all equipment, regardless of funding type. A/E design teams must coordinate with the DoDEA Regional PM for current guidance and to obtain the latest listing of approved systems and software. These items are suggested for use as a basis of design, but are not required. Items not specifically listed on this pre-approved list should be submitted as a separate and independent package to DoDEA HQ with ATTN: Director of Information for review and preliminary approval. DoDEA will only initiate the approval of these systems if they are deemed appropriate.

9. The design and installation of the network must comply with the referenced standards listed under Section 3 above, unless otherwise modified by this document.

5.1 Outside Plant Cables

At the onset of a project, the telecommunications design team must communicate with the installation community responsible for the telecommunication facilities, network infrastructure, and distribution system. In particular, the discussion must identify the location and capacity of the existing available fiber optic and copper cables in the proximity of the project, including testing of the existing cables that will be assigned to the project. The design intent is to provide a dedicated 24 strands of OS2 single mode fiber optic cable and a 50 pair copper cable from the installation’s demarcation point to the new school. A minimum of 100 pair of copper must be used when there is a school community system service point, previously referred to as a “complex”. Any deviation from this standard (increase or decrease) must be documented in writing and signed off by both the Installation and DoDEA IT. The duct bank routes and splice points must be clearly identified in the facility construction documents. All Outside Plant (OSP) cables, raceways, and codes must be compliant with the local authority having jurisdiction in the location in which the work is being performed.

A/E prepared construction documents must include detailed drawings of all requirements, governed by the I3A and local military community telecommunication standards, for the OSP. These must also include, but are not limited to, the number and type of conduits, conduit spacers, tie downs, tracer wires, ground warning tape, splice points, cable vaults, pedestals, any inner duct, maintenance holes, minimum burial depths, all internal maintenance supporting hardware, and details that depict how the OSP must enter into a building.

The OSP, including both fiber and copper cables, must enter underground into the main telecommunications room, designated as TR1. All entry cables using wall must be dressed and secured properly to said wall. All OSP entry conduits must transition from Polyvinyl Chloride (PVC) piping to Rigid Steel Conduit (RSC) prior to entry into TR1. The transition from plastic to RSC for entrance conduits must take place at the bottom of the trench prior to sweeps or bends to the building. Entry conduits will have innerducts installed and sealed with proper duct plug or other expanding foam sealant.

MaxCell will be tied off on both ends to avoid retracting into the conduit. Refer to the TR1 floor plan drawing in Figure 1 for the configuration of the room and cable entrance locations.

The incoming copper cables must be terminated in a protected entrance terminal (PET) enclosure with a built-in splice chamber, 5 pin gas protector modules, locking cover, and output on 66 blocks, 110 blocks, or RJ21 connectors. Copper will then be routed from output blocks to ladder trays and into separate equipment racks. The connections must be terminated in the racks on patch panels specifically designated for voice services. The incoming fiber with interlocking armor/metallic member (if used) must be grounded to the nearest busbar before entering the 7’ racks (48U only). Copper and fiber OSP feeds must be labeled behind 7’ rack at patch panels. Copper will also be labeled at splice point at PET and 110 blocks with cable number and pair count. Fiber feeds must be labeled with cable number and count.

Fiber and copper feeds must be routed to rack and given a 10’ service loop on top of ladder tray. These cannot be service looped inside vertical wire manager, as the bend radius will be exceeded.

5.2 System Requirements

A. Main Telecommunications Room and Entrance Facility

1. The room must be rectangular with minimum dimensions of 10’x24’ and a 10’ minimum ceiling height. The room must have a solid ceiling, as opposed to a drop ceiling. The walls must extend from true floor to true ceiling, with permanent construction for physical security. The room must also have only one door, including a self-locking utility style handle at a minimum of 36” wide.

Refer to DoDEA Protection Criteria 4-010-01 for additional information on door hardware function and Physical Access Control System requirements. The room cannot have exterior windows. In the Americas (AM) and the Pacific (PAC), all walls must be covered with 4’ x 8’ x 3/4” painted plywood from 6” Above Finish Floor (AFF). The plywood must be mounted in a vertical position, adjoined to minimize seams, contain no knots, and have an “A” grade exposed face. Fire retardant treated (FRT) and AC rated plywood is required for compliance with applicable building codes. In addition, fire retardant paint must be used to paint the plywood. In EU, the plywood is not required, assuming there is no equipment to be mounted on the wall.

2. In order to mitigate the potential conflict of electromagnetic interference (EMI) or future expansion, TR1 cannot be located adjacent to any electrical rooms, mechanical rooms, stairwells, elevators, or other restrictive building components. The racks within TR1 must maintain a minimum separation of 4’ from any electrical equipment.

3. The floor shall be static dissipating (anti-static) tile and coated to reduce dust.

4. The room must have a dedicated cooling system independent from the mechanical system serving the rest of the building. No racks or equipment can be located under a cooling unit that could potentially drip condensate onto them. The cooling unit must be installed over the entry door and not over any IT infrastructure equipment or cable trays. TR1 must have its own thermostat and the units must be able to resume preset cooling temperature after a power outage without manual adjustment. The room must be provided with positive pressure to minimize dust intrusion. All conduits and penetrations into the room will be sealed completely and fire stopped. The cooling unit drain must be continuous, with no break until it is outside of the TR. Heat load produced by the equipment will determine the size of the cooling system installed. The designer must provide heat load estimates based on equipment systems that must be installed in the TR1 to support building systems.

5. Any equipment or utility unrelated to TR1 must not be installed in or routed through this room.

6. This room must be dedicated to systems described herein.

7. The room must contain a minimum of four, side-by-side, two-post equipment racks, and three four-post equipment racks, with 6” vertical cable managers on both sides of each rack, secured at the top and bottom with adequate space on both ends. “Adequate space” means a minimum of 36”. Two of the four-post racks will be dedicated for Electronic Security System (ESS) equipment. Any mounting studs must be cut flush or covered with plastic covers for safety. IT will interconnect these cabinets as part of the outfitting process. Refer to Figure 1 - Figure 6 for additional information. Minimal electrical requirements can be determined using the adjacent diagram.

8. For Site Service Point (SSP) locations, two (2) additional racks must be installed in TR1 to accommodate servers, backup solution(s), voice gateway, Uninterruptable Power Supply (UPS), and other related networking equipment. Racks in TR1 for SSP locations will be four-post or ventilated cabinets with built-in fans installed. The designer will confirm if a MILCON site is designated as an SSP location with DoDEA IT.

9. TR1 must have standard telephone communication system wiring and outlets.

10. Rack 1 must be dedicated to horizontal data cabling for data drops located in the proximity of

TR1. Switches and patch panels, as described below, must be installed in Rack 1 to a maximum of 240 cables. Refer to Figure 6 for additional information.

11. Rack 2 must be used for termination of all voice and wireless distribution cabling. Refer to

Figure 6 again for more information.

12. Rack 3 must be used to support video distribution and any requirements for public address intercom and clock systems. Community Access Television (CATV) must be approved by the Director. Refer again to Figure 6 for additional information.

13. Rack 4 must contain the fiber optic termination and distribution equipment in the topmost part of the rack. The site incoming fiber must terminate in this rack. The outgoing fiber to each additional TR and/or adjacent racks must originate in the top of this rack. Refer to Figure 6 for additional information on this.

14. All racks must have a minimum clearance of 3’0” from any face of the equipment, including sides of end racks, to any wall or wall-mounted equipment.

15. TR1 must be illuminated to an average of 50 foot-candles at 36” AFF position at front and rear of racks to avoid shadows on the primary rack surface planes. Light emitting diode (LED) lighting must be a minimum of 5” away from racks, cable trays, and ladders.

16. Install 20A, 120V duplex receptacles on the perimeter walls at approximately 6’ on center (o.c.), including three (3) receptacles per dedicated circuit. In EU, use the host nation electrical standard i.e. 240V at most locations. In addition, provide two dedicated 20A, 120V (or host nation standard) circuits that terminate in twist lock receptacles mounted on the top rear of each rack for connection to remotely manageable power distribution units (PDU) with ammeter mounted within the racks (one per rack). Note that no equipment will ever require 208V connections. For host nation projects, coordinate with the Facilities Project Manager to include local power requirements.

17. The PDUs at each of the racks must incorporate switching technology to provide a manageable system for remote control, alarms, current monitoring, and power delays. The system must be web based, allowing the user to access, configure, and manage the units from remote locations.

PDUs for network equipment must be GFGI. However, separate PDUs must be provided by the contractor as needed to support any contractor furnished and contractor installed (CFCI) equipment such as intercoms or analog video (AV) systems. These PDUs must be installed at the top of the rack and horizontally aligned, as shown in Figure 6. The contractor must provide IT and facilities with the make, model, and serial number of the PDUs, as well as the building number, room number, and cabinet number for industrial control tracking.

18. All special systems will be designed with horizontal wire management included. Wire managers shall be used to dress associated cabling upon installation.

19. TR1 provides a 100-amp and 120/208 volt (or host nation standard) power panel. Additionally, a three-phase power panel board must be located on the wall to give easy access to the power circuit, allowing them to be de-energized to have available power in the room to accommodate any additional circuits that may be needed in the future. An emergency power shutoff will be installed in all main TRs.

20. Comply with all fire code regulations. At minimum, provide a smoke/ion detector mounted on the ceiling. Provide a Category C Fire Extinguisher for electrical equipment mounted on the wall. Provide a fire alarm notification appliance, such as a speaker or strobe mounted on the wall.

B. Secondary Telecommunications Rooms

Secondary TRs must be located only where required to limit the total length of CAT6 copper cable needed from the patch panel to the furthest outlet. The maximum length must not exceed 275’, as measured through the cable tray pathways and in-room routing, to include vertical rises and drops. The 275’ limit provides for sag and unexpected downturns of pathway, as well as patch cables at the wall outlets. Each level of a multi-story facility must contain a minimum of one TR. These rooms must meet the same requirements as TR1, except for the following:

1. This room must be dedicated to Local Area Network (LAN) equipment, as Electronic Security System (ESS) equipment is needed in each TR. The TR must be used to distribute or terminate fiber optic and copper cables to any location other than TR1. Refer to Figure 7 for additional information.

2. The room must be a minimum size of 10’x10’ with a 10’ minimum ceiling height. It must have only one door, minimum 36” wide. Refer to DoDEA Protection Criteria 4-010-01 for additional information on door hardware function and Physical Access Control System requirements.

3. If located on exterior walls, the room must have no exterior windows. In the Americas and

Pacific, all walls must be covered with 4’ x 8’ x 3/4” painted plywood from 6” AFF. The plywood must be mounted in a vertical position, adjoined to minimize seams, contain no knots, and have an “A” grade exposed face. Fire retardant treated (FRT) and AC rated plywood is required for compliance with applicable building codes. In addition, fire retardant paint must be used to paint the plywood. In EU, the plywood is not required, assuming there is no equipment to be mounted on the wall.

4. The room must contain at least one freestanding four-post equipment rack, secured at the top and bottom, and an associated cable management system must be included. The room layout must indicate planned space for a future rack.

5. The incoming fiber optic cable from TR1 must terminate in the upper most part of the rack.

6. CAT6 patch panels for the horizontal cables must be located below the fiber optic patch panel, leaving a minimum of two (2) rack units (RU) of space between the Fiber Optic Patch Panel (FOPP) and the first CAT6 patch panel. This allows space for the enclosed cable management system.

7. Install additional racks and cable management systems as needed for the quantity of horizontal cables terminated. It must also provide space in the data racks for the active equipment that must be furnished and installed by DoDEA.

8. The rack configuration for these rooms must include physical parameters to mount an additional rack to accommodate future expansion. In Europe, the additional rack must be provided. All racks must have a minimum clearance of 3’0” from the face of the equipment, including sides of end racks, to any wall mounted equipment. Refer to Figure 7 for additional information.

C. Video Distribution

As noted above, the video distribution must originate in Rack 2 of TR1, and must be routed through the respective secondary TR if needed. The video distribution in the teaching spaces should preferably be provided through the Interactive Flat Panel (IFP). Each IFP must have a cart mounted unit that connects to the wall outlet through an attachment CAT6 cable with strain relief. Refer to Appendix 1 of the Special Systems Guide for additional information. IFP connections must be shown in the IT Connections Matrix in Appendix 1.

The exact placement of the IFPs must be coordinated with the entire design team and user group to ensure they are set up in optimal locations. IFPs may also be portable, which requires an electrical connection and wired/wireless data connections. Refer to the IT Connection Matrix in Appendix 2. The diagram is a representation of how an IFP can be connected. Note that most IFPs typically include integral speakers, but this must be verified first with the DoDEA Regional PM. Supporting items such as speakers, video display systems, and computers are GFGI, whereas data and power connections are CFCI.

D. Wireless Connectivity

The A/E must designate the location of the wireless access point (WAP) outlets to provide full and optimal coverage relative to the actual design conditions of a project, including room layout, heights, and building materials utilized. The density of the wireless usage is expected to increase over time. The quantity and location of the wireless data points included in the original design must be based on total student population, and must assume laptop operation by every student and staff member. Each “neighborhood” may have up to 120 students and/or wireless network devices.

Each primary teaching space, which does not include one-to-one and group learning rooms, must have a minimum of one ceiling mounted WAP outlet. Adequate wireless coverage must be demonstrated through the wireless heat map deliverable as shown in Figure 14. Note that WAPs must be centrally located for optimal coverage, and facility mapping of wireless zones coverage must be considered accordingly.

Each WAP location must have two (2) Powered Over-Ethernet (POE) network drops. Each location will be identified with an orange dot or mechanical labeling with minimum size 34 font on drop ceiling grid directly below network drops location. For ceiling mounted WAP locations, cables will be terminated in an outlet either flush with the drop ceiling or above the ceiling, no more than 18” above ceiling elevation.

All WAP outlets will be installed with faceplates. For any outside WAP locations, drawings will utilize a separate identifier. Inside WAP locations that are wall-mounted must have faceplates with RJ45 connections provided. Outside WAP faceplates will be stainless steel with a bulkhead RJ45 jack. Each jack and plug shall incorporate a waterproof seal. A tethered protective cap shall be supplied. 3’ industrial patch cords with matching bulkhead connectors shall be provided for all outside WAP locations, plus 10% spares.

Gymnasiums will have WAP coverage for the entire open gymnasium area (4 each). The maximum height for WAPs must be no more than 12 ft. Wall mounted WAPs in gymnasiums will have protective enclosures. The A/E and contractor must coordinate with DoDEA IT on the current WAP part number to determine the minimum size requirements of the appropriate enclosure.

E. Telephone Systems

The telephone system requirements must be coordinated with the military community telecommunications authority to ensure that all new equipment is compatible. The intent is to design a voice system that is compatible for use with VoIP systems where available. All cabling, routing, and limitations apply to the voice cabling as well. VoIP systems must be Defense Information Systems Agency (DISA) and Joint Interoperability Test Command (JITC) approved. Those systems must also be on the Approved Products List (APL). Teachers and administrators must distribute GFGI telephone handsets throughout the building for use. An outlet for a wall phone used for safety, courtesy, and convenience is required in the electrical, mechanical, and TR rooms on a single-gang, single-position modular outlet with a mounting lug faceplate.

F. Equipment Racks

Equipment racks must meet the following requirements:

1. Equipment racks must be freestanding standard Electronic Industries Alliance (EIA) 19” racks with 84” overall height and secured at the top and bottom (45 units). Racks must be furnished with 6” vertical finger-style cable management system with doors mounted on both sides of each rack or between adjacent racks. The vertical cable management system must be installed on the front and rear of all racks. Racks will also contain the cable patch panels, Neat Patch organizers, switches, fiber optic patch panels, and government furnished equipment (GFE). Vertically mounted rack grounding busbars will be installed in all racks and cabinets.

2. A minimum allocation of 25% spare capacity must be included in the bottom most part of all racks. Additional patch panels must be installed in the rack to achieve the number of spare ports required for the 25% spare allocation.

3. Rack elevation drawings for TR1 and each other TR room must be provided. The elevation must clearly show the number and configuration of each rack. Detailed information, including the number of GFGI switches, patch panels, Neat Patch panels, CFCI wire management, and PDUs must be provided by A/E in design and in shop drawings by the contractor as needed to support any CFCI. The number of terminated cables and the total number of available ports must be illustrated as well. Refer to Figure 6, Figure 7, and Section 5.2.D. (Wireless Connectivity) for additional information.

4. Plan TR spaces for an additional future rack location. Figure 6 and Figure 7 provide additional information.

5. A full complement of rack screws shall be provided to DoDEA for each equipment rack or cabinet installed. Cage nuts will also be provided, if necessary, for equipment mounting.

G. Patch Panels

Patch panels must be 48-port CAT6. In addition, each port must be sequentially numbered from left to right 1-24 on top and 25-48 on the bottom. Installation must include a Neat Patch (2U) horizontal wire manager below the 24-port (single unit, single row) or below the 48-port (double unit, double row) panels, leaving a 1U open space below for customer provided switches. Triple row panels are not allowed. Repeat this step for the quantity of patch panels provided, and refer to Figure 6 - Figure 7 for additional information.

Terminate cables by color and function using T568B configuration in the following order:

1. Blue – Data (minimum 10% open ports per rack for future use)

2. Red – Video Distribution, (4-6 open ports per rack for future use)

3. Orange – Wireless, (4-6 ports open per rack for future use)

4.
