Collecting Required Tools and Supplies Installation and Configuration Important Guidelines Even though APs have been engineered for easy installation, there are some very important guidelines to keep in mind: • PLACE the AP NO MORE THAN 140 FEET APART. Placing them farther apart almost always results in poor coverage. • DO NOT MOUNT APs OUTDOORS. • DO NOT MOUNT the APs ON BUILDING PERIMETER WALLS UNLESS THE OPERATOR WANTS TO PROVIDE COVERAGE OUTSIDE THE BUILDING. • BE SURE that plenum-mounted APs are powered using Power over Ethernet (PoE) and use only the metal brackets (not the Ceiling-Mount Base or the Hanging-Ceiling Clips) to comply with safety regulations. • BE SURE THAT the APs ARE INSTALLED VERTICALLY. Installing them vertically standing up in a plenum or hanging from a ceiling creates the largest coverage area per AP. Hanging the APs from the ceiling provides the best RF coverage. 135662 • DO NOT MOUNT the AP ANTENNAS WITHIN ONE METER (3 FT.) OF ANY METAL OBSTRUCTIONS. THE RF WAVES FROM the APs ARE BLOCKED AND/OR REFLECTED BY METAL OBJECTS such as metal HVAC ducts, conduit, pipes, bookcases, elevator shafts, stairwells, and metal walls. REFER TO THE Cisco 1000 Series IEEE 802.11a/b/g Lightweight Access Point Deployment Guide BEFORE MOUNTING the APs NEAR METAL OBSTRUCTIONS. 1 meter (3 ft.) clearance 135659 • WHEN MOUNTING the APs IN THE CORNER OF A RIGHT-ANGLE HALLWAY INTERSECTION, MOUNT THE them AT A 45-DEGREE ANGLE TO THE TWO HALLWAYS. The AP internal antennas are not omnidirectional and cover a larger area when mounted this way. 135660 When AP is configured with an IP address and is moved to a different IP segment, it attempts to join a Cisco Wireless LAN Controller. If it is unable to join a Cisco Wireless LAN Controller after a number of attempts, it does an arp for the default configured gateway. If the AP is on the wrong subnet, it will not be able to resolve the gateway arp and it will attempt to contact a DHCP server. This is the AP IP address fallback feature. However, if the destination IP segment does not have a DHCP server, the AP retains its original IP address and can never join the network.
