Additionally, observe the following items before mounting or connecting the access point:WARNING: To comply with FCC radio frequency (RF) exposure limits, a minimum body-to-antenna distance of 20 cm (8 in.) must be maintained when the access point is operational.WARNING: To avoid possible injury or damage to equipment, you must use power supply equipment that is safety certified according to UL, CSA, IEC, or other applicable national or international safety requirements for the country of use. All references to power supply in this document refer to equipment meeting these requirements.Installation Item DescriptionSwitch port 3Com recommends that you install and configure the 3Com Wireless LAN switch before installing the access point. Set the port type on the switch to an AP2750 access point.Cabling Make sure that standard Category 5 cable with straight-through signaling is installed at the site before you install the access point.Make sure that the cable is highly flexible and that there is no extra covering on the RJ-45 connector that could prevent the cable from being routed through the mounting bracket.Power Requirements Power can be supplied via an 802.3af Power Over Ethernet (PoE)-compliant device or by an external power supply with a minimum 5v @ 2.0 amp.If using an external power supply, make sure the power outlet is accessible. The power supply plug is the only means of disconnecting the access point from power. MAC Address Record the access point MAC address in a safe place before the access point is installed in a hard-to-reach location.The MAC address is printed on the back of the access point. Additional MAC address labels are shipped with the access point.
3 Attaching the AntennasCarefully unpack the standard detachable antennas. Screw the antennas on to the antenna connectors on the access point and hand-tighten them. After network startup, you may need to adjust the antennas to fine-tune coverage in your area.For best results, adjust the antennas so that they are perpendicular with the floor and ceiling.4 Mounting the Access PointThe access point can be mounted on the following types of surfaces:• Wall, ceiling, or electrical box (NEMA enclosure)•Tabletop. Wall, Ceiling, or Electrical Box MountingTo mount the access point to a wall, ceiling, or electrical box:1Remove the access point from the mounting bracket.2Screw the mounting bracket to a wall, ceiling, or electrical box (NEMA enclosure):•If mounting to a solid surface wall or ceiling, use the two sheet metal screws.•If mounting to drywall, use the two sheet metal screws and two wall anchors.•If mounting to an electrical box (NEMA enclosure), use the two threaded screws.3Route the power cable (if using an external power supply) and Ethernet cable through the large opening on the back of the mounting bracket. . CAUTION: Do not handle the antenna tips, especially after they are connected to the access point. This could lead to electrostatic discharge (ESD), which could damage the equipment.CAUTION: The access point is intended for indoor use only. Do not install the access point outdoors unless you install it in a properly installed outdoor access point enclosure.CAUTION: For easy installation and removal of the access point from the mounting bracket, make sure that there is sufficient flexibility with the cable and that there is adequate service loop (that is, enough cable routed through the mounting bracket to easily connect the cable to the access point.) If not enough cable is routed through the back of the mounting bracket, or if the cable is inflexible, it can be difficult to install or remove the access point from the mounting bracket.
