Chapter 2: Site Preparation Planning Your Site To install your equipment successfully, you should plan the site carefully.
Meeting Site Requirements The organizations listed in Table 8 are authorities on electrical codes. Table 8: Authorities on Electrical Codes Organization Address Web Site URL National Electrical Code (NEC) Classification (USA only) NFPA 1 Batterymarch Park Quincy, Massachusetts 02169 USA http://www.nfpa.org UL 333 Pfingsten Road Northbrook, Illinois 60062-2096 USA http://www.ul.com NEMA 1300 N. 17th Street Rosslyn, Virginia 22209 USA http://www.nema.
Chapter 2: Site Preparation NOTE Extreme Networks recommends that you consult an electrical contractor for commercial building and wiring specifications. Temperature It is important to keep installed equipment within the thermal operating specifications for optimum performance and safety. Install the E4G-400 Cell Site Aggregation Router only in a temperature-controlled and humidity-controlled indoor area that is free of airborne materials that can conduct electricity. Too much humidity can cause a fire.
Meeting Site Requirements Electrostatic Discharge Your system must be protected from static electricity or electrostatic discharge (ESD). Take the following measures to ensure optimum system performance: ● Remove materials that can cause electrostatic generation (such as synthetic resins) from the equipment location. Check the appropriateness of floor mats and flooring. ● Connect metal chassis, conduit, and other metals to ground using dedicated copper grounding lines.
Chapter 2: Site Preparation Protective Grounding for the Rack Use a rack grounding kit and a ground conductor that is carried back to earth or to another suitable building ground. At a minimum, follow these guidelines to ground equipment racks to the earth ground: ● CAD weld appropriate wire terminals to building I-beams or earth ground rods. ● Use a minimum 14 AWG stranded copper wire for grounding an E4G-200 series router or a DC-powered E4G-400 router.
Evaluating and Meeting Cable Requirements Figure 12: Properly Secured Rack CSR_030 Brace open equipment racks if the channel thickness is less than 1/4 inch (6.4 mm). Outdoor Installation Sites The E4G-200 series router may be installed in locations outside of buildings. For outdoor installation sites, be aware of the following considerations: ● Prevent unauthorized access to equipment locations and make sure that only qualified service personnel have access to the equipment.
Chapter 2: Site Preparation Cabling Standards Extreme Networks recommends using the Building Industry Consulting Service International (BICSI) Registered Communications Distribution Designer (RCDD), which is globally recognized as a standard in site planning and cabling. For information, go to: http://www.bicsi.org Cable Labeling and Record Keeping A reliable cable labeling system is essential when planning and installing a network. Maintaining accurate records helps you to: ● Relocate devices easily.
Evaluating and Meeting Cable Requirements CAUTION Unshielded twisted pair (UTP) cable can build up ESD charges when being pulled into a new installation. Before connecting any category 5 UTP cable to the router, discharge ESD from the cable by plugging the RJ-45 connector into a LAN static discharge device or use an equivalent method. ● Use plenum-rated cable when it is necessary for safety and fire rating requirements.
Chapter 2: Site Preparation Figure 14: Properly Installed and Bundled Cable for an E4G-200 series Router CSR_029 Fiber Optic Cable Fiber optic cable must be handled carefully during installation. Every cable has a minimum bend radius, example, and fibers will be damaged if the cables are bent too sharply. It is also important not to stretch the cable during installation. Extreme Networks recommends that the bend radius for fiber optic cable equal 2 inches (5.
Evaluating and Meeting Cable Requirements Cable Distances Table 9 shows cable media types and maximum distances that support reliable transmission in accordance with international standards except where noted. In addition, table lists the direct-attach cables that are available for use with the E4G series routers.
Chapter 2: Site Preparation RJ-45 Connector Jackets Use RJ-45 cable with connector jackets that are flush with the connector or that have connectors with a no-snag feature. Using cable with jackets that are wider than the connectors can cause: ● Connectors that are not properly aligned with the port. ● Crowded cable installation, which can cause connectors to pop out of the port. Figure 16 shows examples of connector jacket types that are not recommended as well as those that are recommended.
Meeting Power Requirements Meeting Power Requirements This section describes power requirements and includes the following topics: ● Power Supply Requirements ● AC Power Cables ● Uninterruptible Power Supply Requirements ● DC Power Requirements Power Supply Requirements Follow these recommendations when you plan power supply connections for the E4G series routers: ● Place the equipment in an area that accommodates the power consumption and component heat dissipation specifications.
Chapter 2: Site Preparation Uninterruptible Power Supply Requirements An uninterruptible power supply (UPS) is a device that sits between a power supply (such as a wall outlet) and a device (such as a router) to prevent outages, sags, surges, and bad harmonics from adversely affecting the performance of the device. A UPS traditionally can perform the following functions: ● Absorb relatively small power surges. ● Smooth out noisy power sources. ● Continue to provide power to equipment during line sags.
Applicable Industry Standards UPS Transition Time Transition time is the time that is necessary for the UPS to transfer from utility power to full-load battery power. For Extreme Networks products, a transition time of less than 20 milliseconds is required for optimum performance. DC Power Requirements A DC-powered system should be installed in a DC-I battery return configuration.
