CAUTION: The 3Com power supply (part number 61-0107-000) input relies on a 16A rated building fuse or circuit protector for short circuit protection of the line to neutral conductors. CAUTION: It is the responsibility of the installer to ensure that the Power-over-Ethernet (POE) power supply is properly connected. Connection to any other device, such as a standard Ethernet card or another POE supply, may result in permanent damage to equipment, electric shock, or fire. Refer to the installation instructions for proper installation DECIDING WHERE TO PLACE EQUIPMENT The access point ideally designed for vertical installation on a wall surface, but can also be flat-surface mounted in an elevated location where it will not be disturbed. Ceiling installation is not recommended. Whether you choose to mount the access point on a wall or place it on a flat surface, make sure to select a clean, dry location that is elevated enough to provide good reception and network coverage. Do not mount the access point on any type of metal surface. Do not install the access point in wet or dusty areas. The site should not be close to transformers, heavy-duty motors, fluorescent lights, microwave ovens, refrigerators or any other electrical equipment that can interfere with radio signals. If you are connecting the access point to a wired network, the location must provide an Ethernet connection. You will need to run an Ethernet cable from the power supply to the access point. An access point provides coverage at distances of up to 100 Meters (300 Feet). Signal loss can occur if metal, concrete, brick, walls, floors or other architectural barriers block transmission. If your location includes these kinds of obstructions, you may need to add additional access points to improve coverage. If you plan to use an optional antenna instead of the standard detachable antennas that are supplied, review "" on page 21 before selecting the final location and be sure to allow for routing the antenna cable as required. For optimal performance, ensure the access point operates in temperature ranges between -10˚ C to 40˚ C (14˚ F to 104˚ F). Regulatory restrictions dictate that when this device is operational, the minimal body-to-antenna distance is 1 Meter (3 Feet). 15
