For the safety of people and equipment, only professional network personnel should install 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. 1 Unpacking the Access Point Make sure that you have the following items, which are included with the access point: • • • • Two external 2.4 GHz and 5.3 GHz dual-band antennas Mounting bracket (attached to the access point) Wall-mounting hardware: • Locking bar (used for securing a wall- or ceiling-mounted installation) • Two sheet metal screws • Two thread screws • Two wall anchors Four adhesive rubber feet (used for a flat-surface installation). 2 Preparing for Installation It is advisable to connect the power (if using an external power supply) and check the Ethernet cables and LEDs before installing the access point in a hard-to-reach location. Additionally, observe the following items before mounting or connecting the access point: Installation Item Description Switch 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. 10015413-AA_AP2750_QSG.fm Page 4 Wednesday, July 26, 2006 4:50 PM 3 Attaching the Antennas Carefully 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. 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. Connecting External Antennas The access point has connectors for attaching optional external antennas and antenna cables. The tables below list the external antenna and cable models that are certified for use with the access point. Antenna Model Type 3CWE591 3Com 6/8 dBi Dual-Band Omnidirectional Antenna 3CWE592 3Com 3/4 dBi Dual Band Ceiling Antenna 3CWE597 3Com 6/8 dBi Dual-Band Hallway Antenna Cable Model Type 3CWE580 3Com Ultra Low Loss 6-Foot Antenna Cable 3CWE581 3Com Ultra Low Loss 20-Foot Antenna Cable 3CWE582 3Com Ultra Low Loss 50-Foot Antenna Cable The 3Com antennas are dual-band, which means that they operate in both 2.4GHz and 5GHz spectra. You can use these antennas with either the 802.11b/g radio or the 802.11a radio. Each antenna requires the purchase of a separate antenna cable. NOTE: Antenna cables introduce loss of the RF signal. Always use the shortest cable that your application allows. For installation instructions, see the documentation that is supplied with the antenna. NOTE: During the installation, connect the antenna to the access point before connecting the Category 5 Ethernet cable. This ensures that the access point is not powered on when the access point is connected to the network. 10015413-AA_AP2750_QSG.fm Page 5 Wednesday, July 26, 2006 4:50 PM 4 Mounting the Access Point The access point can be mounted on the following types of surfaces: • • Wall, ceiling, or electrical box (NEMA enclosure) Tabletop . 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. Wall, Ceiling, or Electrical Box Mounting To mount the access point to a wall, ceiling, or electrical box: 1 2 3 Remove the access point from the mounting bracket. Screw 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. Route the power cable (if using an external power supply) and Ethernet cable through the large opening on the back of the mounting bracket. . 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. 10015413-AA_AP2750_QSG.fm Page 6 Wednesday, July 26, 2006 4:50 PM The figures below show the mounting bracket being mounted to a wall, and then a cable being routed through the large opening on the back of the mounting bracket.
