Statement of Conditions In the interest of improving internal design, operational function, and/or reliability, NETGEAR reserves the right to make changes to the products described in this document without notice. [. . . ] The installation location should have a maximum relative humidity of 90%, non-condensing. Do not restrict airflow by covering or obstructing air inlets on the sides of the switch. Keep at least 2 inches (5. 08 centimeters) free on all sides for cooling. Be sure there is adequate airflow in the room or wiring closet where you intend to install the switch. Keep the switch at least 6 ft (1. 83 m) away from nearest source of electro magnetic noise, such as a photocopy machine. Operating humidity: Ventilation: Operating conditions: After confirming that your site meets the requirements in Table 4-1, you are ready to install the switch. installation 4-2 Installing the Switch You can install the NETGEAR FS726 and FS750 Switches on a flat surface or in a standard 19-inch rack. Installing the Switch on a Flat Surface 1. The switch ships with four self-adhesive rubber footpads. Affix one rubber footpad on each of the four concave spaces on the bottom of the switch. The rubber footpads cushion the switch against shock/vibrations. MODEL Figure 4-1. Attaching Mounting Brackets Installing the Switch in a Rack To install the FS726 or FS750 Switch in a rack, use the following procedure (and refer to Figure 4-1). To perform this procedure, you need the 19-inch rack-mount kit supplied with your switch. Attach the supplied mounting brackets to the side of the switch. Insert the screws provided in the rack-mount kit through each bracket and into the bracket mounting holes in the switch. Tighten the screws with a #1 Phillips screwdriver to secure each bracket. Align the mounting holes in the brackets with the holes in the rack, and insert two pan-head screws with nylon washers through each bracket and into the rack. Tighten the screws with a #2 Phillips screwdriver to secure the switch in the rack. Proceed to "Connecting Devices to the Switch. " installation 4-3 Connecting Devices to the Switch The following procedure describes how to connect devices to the switch's RJ-45 ports. When attaching devices to an FS726 or an FS750, the switch's support for Auto Uplink technology allows you to attach devices using either straight-through or crossover cables (for more information about Auto Link` technology, refer to "Auto Uplink " on page 12). Connect each device to an RJ-45 network port on the switch's front panel (see Figure 4-2). Use Category 5 (Cat5) unshielded twisted-pair (UTP) cable terminated with an RJ-45 connector to make these connections. Front Panel of the Model FS726 or Model FS750 Switch (Model FS726 shown) Figure 4-2. Connecting Devices to the Switch Note: Ethernet specifications limit the cable length between the switch and the attached device to 100 m (328 ft). installation 4-4 Using Gigabit Ethernet Modules The modularity of the FS726 and 750 Switches provides you with a highly adaptable network. . You not only can configure your network for copper and/or fiber gigabit uplinks, but you also can opt to expand your network gradually and affordably, as needed. [. . . ] Unlike 10BASE-T and 100BASE-TX, which use only two of the four pairs of wires within the Category 5, 1000BASE-T uses all four pairs of the twisted pair. Make sure all wires are tested -- this is important. cabling guidelines C-6 Factors that affect the return loss are: · The number of transition points, as there is a connection via an RJ-45 to another connector, a patch panel, or device at each transition point. · Removing the jacket that surrounds the four pairs of twisted cable. It is highly recommended that, when RJ-45 connections are made, this is minimized to 1-1/4 inch (32 mm). [. . . ]
