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. NETGEAR does not assume any liability that may occur due to the use or application of the product(s) or circuit layout(s) described herein. [. . . ] Keep the switch away from heat sources such as direct sunlight, warm air exhausts, hot-air vents, and heaters. 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. 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. 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. Press the reset button if the power has remained on throughout the installation of the gigabit modules. installation 4-5 Checking the Installation Before you apply power: · Inspect the equipment thoroughly. · Check cable routing to make sure cables are not damaged or create a safety hazard. [. . . ] If using the existing cable, be sure to have the cable plant tested by a professional who can verify that it meets or exceeds either ANSI/EIA/TIA568-A:1995 or ISO/IEC 11801:1995 Category 5 specifications. Length The maximum distance limitation between two pieces of equipment is 100 m, as per the original Ethernet specification. The end-to-end link is called the "channel. " TSB-67 defines the "Basic Link" which is the portion of the link that is part of the building infrastructure. Return Loss Return loss measures the amount of reflected signal energy resulting from impedance changes in the cabling link. [. . . ]
