[. . . ] Each fully loaded SpectraLink 6300 MCU shelf weighs approximately 35 pounds. Rack mounting Before installing shelves in a rack, be sure the rack is mechanically fastened to the floor or wall such that it properly supports the number 1725-36121-001_K. doc 21 SpectraLink 6300 MCU: Facility Preparation of shelves to be mounted. Follow the manufacturer's instructions to prepare the rack. Be sure to leave 1. 5" clearance at the rear of the racks for power conduit. 22 PN: 1725-36121-001_K. doc Site Preparation Wall mounting Before wall mounting, cover the wall with 3/4" plywood. Secure the plywood to the wall studs every 16" with an adequate number of screws to support the number of shelves to be mounted. Each fully loaded shelf weighs approximately 35 pounds. Be sure to leave 1. 5" clearance on the left side for power conduit. Using the following drawing as a guide, drill six pilot holes using a 1/8" drill bit. Insert the six screws (#10 panhead wood screws, 5/8" long) into the pilot holes and tighten them, leaving approximately 1/8 to 1/4" gap from the wall. Wall Mounting Dimensions Prepare Power for Shelves The SpectraLink 6300 MCU requires a -48V DC power source. The 48V connection is comprised of three wires: -48, +48 (neutral), and ground. 1725-36121-001_K. doc 23 SpectraLink 6300 MCU: Facility Preparation SpectraLink recommends that a licensed electrician install the -48V power source. It must be installed according to current National Electrical Code (NEC) or National Fire Protection Code standards, in accordance with all local and municipal electrical code recommendations. When connecting the -48 V DC system to power, note the following precautions: A 30 amp circuit breaker must be present on the non-grounded DC circuit conductor, and the installer must ensure that means are provided for connection of the equipment to the DC source by permanent wiring methods, and no disconnecting device is located in the grounded DC circuit conductor between the point of connection to the supply and the point of connection to the grounding electrode and equipment grounding conductors. Run Cables to Base Station Locations The Base Station locations should be designated on the building floor plans provided to the field service engineer. Base Stations can be mounted easily on raised or acoustical ceiling tiles, or on the wall. Avoid locating Base Stations in high or hard-to-reach places, as this will hinder maintenance, testing, or repositioning. Wire specifications The customer's wire contractor is responsible for adhering to all local codes for wiring. SpectraLink recommends UL-listed wire that conforms to the following specifications for AWG, distance, and number of power pairs required for this installation. Power Pairs 1 2 3 Max Cable Feet 22 AWG 6, 000 N/A N/A Max Cable Feet 24 AWG 3, 800 6, 000 N/A Max Cable Feet 26 AWG 2, 400 4, 800 6, 000 24 PN: 1725-36121-001_K. doc Site Preparation One additional pair is also required for data. For wire runs of less than 3, 500 feet, attenuation must not exceed 6. 8 dB/1, 000 feet at 772KHz. For wire runs between 3, 500 and 6, 000 feet, attenuation must not exceed 4. 5 dB/1, 000 feet at 772KHz. Wire that is already installed (spare house cable) can be used when it is available. House cable will usually run from the MDF in the telephone equipment room to intermediate distribution frames (IDFs) spread throughout the facility. Install new wire from the closest IDF to the Base Station. Be sure no bridge taps, multiples, or "Y" connections are created or present. Determine the amount of wire needed to connect the Base Station to the MCU by scaling from a floor plan or a sketch, pacing, measuring, or estimating. Remember to include enough wire to reach the ceiling. [. . . ] Two-pair wires are run to each of the Base Station locations as designated on the building floor plans. Use Level 3 cable for lengths up to 3, 500 feet; Level 4 for lengths up to 6, 000 feet. The Base Station cables are terminated with RJ-45 crimp-on plugs at the designated locations. See Chapter 3 section Prepare Demarc Blocks. PN: 1725-36121-001_K. doc 45 SpectraLink 6300 MCU: Facility Preparation One (or two) cross-connect block(s) are installed for every Interface Module and connected with a 25-pair telco cable terminated with an RJ-21 male connector at the MCU location as shown in Chapter 3 sections Install Demarc Blocks and Program Telephone System.
