AT-FS750/16 and AT-FS750/24 Fast Ethernet Smart Switches Installation Guide Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
Chapter 2: Installation Selecting a Site for the Switch Observe the following requirements when choosing a site for your switch: If you plan to install the switch in an equipment rack, ensure that the rack is safely secured and that it will not tip over. Devices in a rack should be installed starting at the bottom, with the heavier devices near the bottom of the rack.
