This section provides information on the floor and wall space required for system equipment and associated peripheral equipment installed in equipment rooms. Also included are Specifications for temperature, humidity, air purity, and lighting levels. B. Floor Loading 1. These requirements apply to any physical surface on which the equipment is placed. 2. Floor loading of equipment cabinets varies from 50 to 250 lbf/sqft. Because of this range - and to accommodate the widest variety of equipment over the life of the building - the floor rating under distributed loading must be greater than 100 lbf/sqft and the rating for concentrated loading must be greater than 2000 lbf/sqft in areas that will support telecommunications equipment. Check the manufacturer's specifications to ensure a compatible floor rating before installation. 3. These requirements apply to any physical surface on which the equipment is placed. 4. Specific project requirements may require unique support. Local codes may dictate design (earthquake issues, etc.). C. Security 1. Access to the room must be through secured doors with keyed entry and/or UTPD (University of Texas Police Department) Security card readers that allow the passage of wide equipment. The minimum door size will be 36 inches, and it should open toward the outside of the room. Automatic closer and self-latching locks should also be provided. 2. All communications rooms must occupy a sector of the building, which does not touch an outside wall, unless the outside wall is structural concrete, or other impermeable structural material capable of withstanding known environmental and civil hazards. It must be secured at all times by a locking mechanism whose key is made available only to appropriate personnel. All IS related communications rooms shall have keyed entry and/or a UTPD Security card reader installed at the entrance door(s). Every effort should be made to see that the main communication room is not located on the ground floor or below ground floor. 4 OF 42

PART 6 - PATHWAYS, CABLE TRAYS, WIREWAYS AND CONDUIT 6.01 GENERAL A. All structured cabling will be installed in a cable tray, wireway, basket tray or conduit and cross perpendicular to fluorescent lighting and electrical power cables or conduits. All cables shall remain within the M.D. Anderson Cancer Center approved pathway, cable tray, wireway, basket tray and/or conduit until necessary to breakout at the work area. Do NOT install structured cabling in elevator shafts, as this will cause electrical interference. Ceiling support wire or rod will not be the means of supporting cables and the cable will not be laid directly on ceiling tile. In addition, communications cables will not be supported from conduits or wireways containing power circuits. B. Cable trays are the preferred method of installation. J-hooks can also be used. Ceiling support shall be at a maximum of five (5) foot intervals and should be placed as close to the deck as possible. Basket trays can be used as an alternative to cable trays. Cable pathways shall be so configured to avoid EMF and RFI interference. ALL CABLE RUNS MUST BE A MINIMUM OF 12 FROM ALL FLORECENT LIGHTS and EMF SOURCES. C. Ladder Trays 1.

Any implementation of this tray will include spill brackets at all inside corners. D. Cable Trays 1. It is required that the cable tray should be installed parallel to furred-out wall 6 to 12 inches inside the MDR/IDR. Tie into cable trays, routed throughout the building, must have a continuous path for all cables to run in. The cable tray should continue into the IDR/MDR to deliver the riser, station/horizontal, and fiber to the end destination (i.e., rack, wall field, or XLBET). 22 OF 42

In addition, the vertical cable trays should be mounted on fire rated plywood or solidly anchored to the wall so as not to pull loose. 3. Floor and ceiling penetrations for all riser cabling (fiber and/or copper) will have a vertical tray installed to support all communications cabling. The vertical, ladder-type cable tray to be a minimum of 18 inches wide with 4 inch side rails. This cable tray should meet the specifications as stated below. All vertical riser cabling to be secured to relieve stress (minimum of 3 each per floor). It is preferred to have the vertical penetrations lined up through the floors for a continuous vertical cable tray path, especially in new building design. Otherwise, the concrete penetrations must have an acceptable form of protection installed to avoid cable contact with the concrete. 4. All cables shall be secured when exiting or leaving the cable tray and will have proper support. 5. Cables shall be supported every 5 feet per BICSI-568-B and not sag between J- hooks. If the cable does sag it means that an additional J-hook is required for proper support. 6. Cable tray located above the ceiling must meet the following recommendations: a.

In addition, the maximum distance on any suspended cable run will not exceed 5 feet (1.5 meters). All cables exiting or leaving the raceway must be supported within 5 feet with an M.D. Anderson Cancer Center approved support method. Hook-and-loop or cable management rings are to be spaced no greater than 5 feet (1.5 meters) apart. They are not to support more than 50 single 4-pair (or 25 dual 4-pair) cables. Routing through bar-joists may be acceptable in some cases with M.D. Anderson Cancer Center s Network Services and Telecommunications Services approval) provided the bar-joist spacing is not greater than 5 feet. 8. Wireways a. Device boxes should be mounted on wireways. This prevents the jacks from being installed directly in the cable path of the wireway. Installing the faceplate and 23 OF 42

If a conduit requires more than two 90-degree bends, then a junction box must be provided between the sections. d. If a conduit requires a reverse bend (between 100 degree and 180 degree), then a pull box must be provided at each bend having an angle from 100 degree to 180 degree. e.

Any installation requiring a longer distance is to be approved prior to installation by M.D. Anderson project manager. 11. Conduit for Fiber-Optic Cable E. Pull Boxes a. The conduits will run according to the M.D. Anderson Cancer Center approved pathway. Conduits will have a pull box every 150 foot (18 inches X 18 inches X 4 inches) and will have no more than two 90 degrees bends without pull box. The 90 degree bends shall not have less than a 12-inch bend radius. The following information should be noted on the prints for future pulls. Conduits are to have 200 lb test pull rope/mule tape (not Jetline) placed and secured with the length of the conduit run attached. Also note the location of the other end. Conduits running to equipment enter from the bottom (if possible), if on raised floor or floor other than ground floor. This may mean at least two or more phases on conduit run. 25 OF 42
