  8. As-Built plans in AutoCAD format unless given permission for other formats. (The CCI Project Manager will supply the Contractor with a copy of the base floor plan AutoCAD file upon request.) w. QUESTIONS i. If a designated contact has not been defined in a project, use the contacts listed below for all questions:
  1. Divide total quantity of data outlets in half since only half are typically activated
  2. Divide qty. of activated outlets by 24 to determine how many 24-port Ethernet switches are needed
  3. Network Operations then refers to spec plate power ratings on gear, de-rates by 60% to determine running power in watts and multiples by qty. switches
  4. Plug equipment load in watts-to-BTU/hr. equation to determine cooling… 1 W = 3.412142 BTU/hour b. Direction of supply air should be pointed to the front of racks which is the same as the direction of the ports on the patch panels.
  5. Lighting in MDFs & IDFs a. Lighting levels in the wiring Communication Room shall be at least 50 foot-candles at 5 foot above the finished floor at the 19-in. Racks using LED fixtures.

a. Static Dissipative Tiling Floor is to be installed on all floor surfaces within MDFs & IDFs. “Armstrong Fossil Gray Excelon ESD Tile 51956 Static Control Flooring” or similar product.

  1. Doors a. Doors for new communications rooms shall be secured with card readers maintained by CMU’s Access control staff. Locks should provide for bypass key entry in the event that the card reader is not functioning. A pair of bypass keys is to be provided to CCI such that keys are unique to each building. b. On projects where new communications rooms are built, doors must be installed and secured BEFORE networking equipment can be installed. Therefore, responsible CMU parties should direct their contractors and the CMU Lock Shop to complete this in advance of building occupancy (typically no less than 2 or 3 weeks).
  2. Signage a. Signs on doors to communications rooms should only list the room number, not the function of the room (ex: “communications room”). This to not make the function of the communications rooms obvious to unauthorized users.
  3. Environmental Monitoring a. One environmental monitoring system shall be provided for each communications room. Current model is a “Vertiv Watchdog- 100 ” with flood sensor model “VERTIV FS- 15 ”. Monitor is 2RU in height and is to be mounted on 19” rails of communications rack such that it is centered vertically 2’ A.F.F.. Leak Sensor should be secured with one screw into floor, in a low lying spot if available.
  4. Other Systems

a. So as to maintain a secure environment, no other cabling or gear except for that which is in support of the campus network and telecommunications systems are to reside within communications rooms. On an as needed basis, requests have been honored to allow for location of the campus access controllers if space allows. b. All trash/debris is to be removed from communications rooms. iii. Voice Riser

  1. Provide and install a 50-pair cable type A.R.M.M. in conduit or type A.P.M.M. in conduit-less installations (plenum version of A.R.M.M. cable; with aluminum armor tape) between the MDF and each IDF. iv. Maximum length of UTP cabling:
  2. Horizontal cabling between MDF/IDF patch panel and workstation outlet: 90 meters
  3. A safe length for patch cords is 5 meters. In no case should combined patch cord length (at both ends) be greater than 10 meters.
  4. Maximum channel (e.g., horizontal cabling link + both patch cords) length shall be 100 meters. v. Communications Outlets
  5. All new UTP workstation communications cables and outlets are to be installed as Category- 6 A “universal outlets” A.K.A. ‘data’ outlets. These outlets originate from Category- 6 A jacks in the network racks inside network telecommunications rooms. These outlets are capable of being used for either voice or network services. They consist of Panduit® black jacks connected with blue plenum Category- 6 A cable.
  6. Quantity: a. Residence halls i. The rule for student rooms is that there must be at least one data outlet for every student in a room or suite of rooms (at each student’s desk area). ii. Voice outlets (universal outlets used for phone service) shall be provided in common areas such as ‘buggy rooms’, dining rooms, lobbies, and kitchens. iii. Unless specifically directed otherwise by CMU Housing Services Department (forward email proof), install (1) CATV outlet per bedroom, living room, recreation/bar area, etc. iv. Computer clusters and must be wired accordingly. b. For offices i. The general rule is to install a minimum of one data/voice outlet (i.e., two universal outlets/cables) for each occupant of an office. In cases where modular furniture is used, one data/voice outlet per workspace. ii. Install (1) CATV outlet per lounge, kitchen/dining area, etc. c. Note that even if the occupant does not want a data/voice outlet, a minimum number of communications outlets MUST be installed based on the size of the space. If the occupant does not require a data/voice outlet, the following table shall be used to determine the number of outlets. d. Calculation table:
  1. CMU Network Operations is the only group who determines the locations of Access Points (aka: “AP’s”) for 802.11 Wireless LAN service (aka: “WiFi”). Network Operations performs a rough design for planning, then performs final location verification after certain construction has been completed, ex: completion of walls/doors). This is relevant for all new campus buildings, major renovations and for smaller campus building renovations whose wireless infrastructure will require redesign. Even so-called minor renovations can impact wireless coverage— especially if walls are moved, added, or removed. Therefore, Computing Services personnel must be invited into discussions early on, during the planning phases of these projects.
  2. Only CMU’s certified communications cabling contractors can remove and install AP’s. CMU’s certified communications cabling contractors are to obtain prior approval from Network Operations or CCI before AP removal. Unless directed otherwise by CCI or Network Operations, changes to AP’s should be performed such to turn off one AP at a time or keep every other AP in a given area operating. This is to prevent a complete outage for wireless service in a given area. AP’s often provide service beyond the areas they are located at, ex: serving offices/classrooms beyond a construction zone.
  3. Cabling for AP’s is to be installed at locations indicated on the rough design and by leaving 20 feet of properly coiled cable slack and unterminated. Cabling can be terminated and AP’s mounted only after final location verification (see above).
  4. Designs shall provide for a minimum of one Access Point for every 200 to 800 square feet (drywall construction) or 50 to 400 square feet (hard plaster or masonry construction) of interior space, depending on capacity: performance ratio. Example: classrooms and lecture halls will require more dense placements.
  5. Each AP location will have two Category- 6 A data outlets installed. The AP’s will receive their power over the data cables (aka: PoE) therefore no 120 VAC power is needed. a. Cable: Panduit # PUP6AV04BU-G this is blue cable b. Jacks: Panduit # CJ6X88TGBL c. Plugs: Panduit #’s FP6X88MTG (straight) & FPUD6X88MTG (angled)
  6. The communications contractor shall install the AP brackets (supplied by CMU Network Services, contact Daryl Hollinger (Manager of Network Operations-CMU Computing Services).
  7. The exact height and location will be determined by CMU Network Operations. a. Send pdf floorplan of project to Daryl Hollinger (Manager of Network Operations-CMU Computing Services). vii. Point-to-point cables
  8. Some campus users have the need for direct, point-to-point cabling between rooms. This cabling can share current pathways only if the following conditions are met: a. These cables are not to be used to extend regular services from existing outlets (in such cases, new outlet(s) should be installed) b. Cables must be our specified brand(s) (Panduit™ for copper UTP) and have a black jacket color this is a black cable c. Cables must be installed in a manner according to our regular standard and be installed by one of our CCI Office approved cabling contractors d. Cables must terminate in a separate faceplate from regular voice/data cables

e. CCI Office will provide labels with a format like: [bldg.#] -- [1st^ room#] – [2nd^ room#] – [xxxx(1-9999)]. The following shows an example of label that could be printed on black, ½” laminated tape by the contractor (using a Brother® P-Touch labeler): f. Cables must be tested according to the “Testing” section in this document

  1. A wide variety of services can be run over Category- 6 A UTP cable including video, sound, CATV, S-video, high def. video, etc., and adhering to our recommendations will help to ensure the following: a. Interference and cross-talk onto current voice/data cabling will be limited b. Cables can be tested, verified and results stored in our current database c. Cables can be given addresses and documented on our AutoCAD drawings
  2. Note: The majority of the cabling we provide is activated with services supported by the Network Operations and Telecom groups. These groups have expertise in troubleshooting and problem escalation. Services on the point-to-point cables are to be directly supported by the customers who are expected to have expertise in troubleshooting and problem escalation. Incorrect troubleshooting could lead to additional contractor charges if cable testing proves no problems found.
  3. Fiber point-to-point cables shall not be zip cord (see “Fiber Cables”) viii. Pathways
  4. Above suspended ceiling a. Office: J-hooks b. Corridor: basket tray
  5. Visible, in corridor a. Priority given to aesthetics (Chalfant Series 6)

Cyert Hall Data Center Spaces… The data center spaces are defined as multiple rooms/floors within Cyert Hall including A82, A84, A100, the ECE machine room on the B-level and the North Lab on the 2nd floor a. Before performing work beneath the floor, contact CCI and Dave Kalbaugh ([email protected]) via email so that he is aware (as building manager) and so he, in turn, can coordinate with FMS to have the subfloor sensors disabled. After receiving confirmation that the sensors have been disabled, commence work. After work is completed, contact CCI and Dave again to have sensors re-enabled. Sensors should be re-enabled before the end of each business day. b. Q: What happens if the procedure is not followed? i. A: As the sub floor area is disturbed, debris can become airborne as well as vibrations can be induced from bumping sensors, both of which may trip sensors. When one sensor trips, a building-wide alarm goes off. When a second sensor is tripped, it starts an automated process to turn off power to the data center within seconds. iii. Cable installation
