1 DIVISION 27: COMMUNICATION General Network Standards and Policies The intent of the network policies are: To ensure that computer networking is treated as an essential component of all new and renovated campus buildings. As such, networks should be designed and funded as part of the basic building infrastructure, just as electrical wiring and plumbing are presently funded. This will also ensure that all faculty, staff, and students in new or renovated buildings will receive readily accessible network connectivity. To ensure that all new or renovated campus computer networks can reliably communicate with all other networks in a manner that secures current and future ability to communicate with colleagues both on campus and beyond. Implementation of the network standards is straightforward. Anytime your area is involved in planning a network, renovating an existing network, building a new building, or renovating an existing space, University of Nevada Information Technology/Networking department must be contacted, prior to the start of your project. For a detailed copy of our campus network standards contact the IT/Networking department. Their staff will work with you to smooth out the details, including network standards in all phases of your project. They will also assist you in ensuring that all appropriate network costs are included in your project budgets. Executive Summary of Network Policies and Standards All campus computer networks that connect to or at some future date might be connected to the building-to-building backbone, must follow The University of Nevada Campus Telecommunications standards, and adhere to the following: Codes and Standards All work shall meet all applicable codes and standards, including but not limited to: National Fire Protective Assoc.
