Patch panels shall be Category 6 48-port patch panels (loaded) and consist of the panel, wiring blocks, rack mount strain relief bar, and port modules. 6. Patch panel shall mount to TIA-EIA compliant 19 rack mount bracket. It shall utilize standards compliant RJ45 jacks for station cable termination. 7. Jacks or inserts shall be RJ45, 6-port modules with individually replaceable jacks in accordance with TIA/EIA 568B wiring standard, FCC Part 68, UL listed, NEC Article 800. It shall accommodate 110- type jack of the 4-pair Category 6 cable. Jack shall support Gigabit Ethernet, 100 Base-T, 10 Base-T and analog connections. 8. Backside strain relief shall be provided for every row of ports. It shall be attached to the TIA/EIA compliant rack via rear mounting holes. Camera (Station) Outlets 1. BISCUIT OUTLETS: Biscuit-type outlets will be utilized for camera connections. 2. JACKS: Category 6 RJ45 unshielded modular jacks shall be utilized. The jacks shall meet or exceed TIA/EIA 568-B.2-1 and IEC requirements for Category 6 component performance. Jacks shall be capable of Gigabit Ethernet, 100 Base-T, 10 Base-T and analog connections. Wiring scheme label shall permit T568A or T568B wiring pattern. T568B wiring scheme will be utilized. 3. Modular jacks shall be terminated using 110-style pc board connectors. The 110style connectors shall be capable of terminating AWG solid core wire. 110 Contacts shall be paired (with additional space between pairs) to improve crosstalk performance. Each jack shall be provided with a bend-limiting strain relief. All jacks shall be terminated using manufacturerspecified jack termination tools and methods. 4. UTP Jacks will be color coded blue. 5. Cameras mounted on exterior of building will be connected to the biscuit-type jacks provided in #1. Camera s will not be hard wired back to main data frame. 6. There are a total of (28) camera s for the library, each location requires 2 drops for a total of Only 1 camera will be connected at each location, the 2nd cable is for future use. Label cables, outlets, patch panels, and punch blocks sequentially.

3 8. Label each outlet with permanent self-adhesive label or insert with minimum 3/16 in. high characters. 9. Label each cable with permanent self-adhesive label wrap with minimum, 1/8 in. 10. Labeling and marking shall be in accordance with TIA/EIA-606 the Administration Standard for Telecommunications Infrastructure of Commercial Buildings.
