Chapter 3: Installation Pre-Installation Considerations Full-Duplex Considerations The Switch provides full-duplex support for its RJ-45 ports. Full-duplex operation allows data to be sent and received simultaneously, doubling a port's potential data throughput. If you will be using the Switch in full‑duplex mode, the maximum cable length using Category 5 cable is 328 feet (100 meters). 1000BASE-T Cable Requirements All Category 5 UTP cables that are used for 100Base-TX connections should also work for 1000Base-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or Category 6 cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000Base-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3ab standards. Positioning the Switch Before you choose a location for the Switch, observe the following guidelines: • Make sure that the Switch is accessible and that the cables can be connected easily. • Keep cabling away from sources of electrical noise, power lines, and fluorescent lighting fixtures. • Position the Switch away from water and moisture sources. • To ensure adequate air flow around the Switch, be sure to provide a minimum clearance of two inches (50mm). • Do not stack free-standing Switches more than four units high.  24-Port 10/100/100 Gigabit Switch
