Ethernet Port The Ethernet port provides a 10/100BASE-TX Ethernet connection to a 3Com Wireless LAN switch. The connection can be direct to a 3Com switch or indirect through an intermediate Layer 2 or Layer 3 network. Use a standard Category 5 cable with straight-through signaling and standard RJ-45 connectors to connect the access point to the switch on the network. -
Page 3: Observing Safety Precautions
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. -
Page 4: Attaching The Antennas
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. - Page 5 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. C radle Installing the mounting bracket Routing a cable Connect the Ethernet cable (and power cable, if applicable) to the port(s) on the front of the access point.
- Page 6 WARNING: Do not connect or disconnect cables or otherwise work with the access point during periods of lightning activity. You can connect the access point directly to a 3Com Wireless LAN Switch port or indirectly to 3Com Wireless LAN switches through an intermediate Layer 2 or Layer 3 network. In either case, use Category 5 cable with straight-through signaling for each access point connection.
