Figure 3 A ccess Point Right Side Co nnections Radio Operation The 2.4-GHz radio supports three antennas fo r mu lti-input, single output (MISO) operation. The radio uses three receivers to support maximu m ratio combining (MRC) to enhance receiver performance. MRC is a technique that combi[...]

10 External Antennas War n in g In order to comply wi th radio frequency (RF) exposure limits, the antennas for this product should be po sitioned no less than 6.56 ft (2 m) from your body or nearby persons. Statement 339 War n in g Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come i[...]

11 Note T o reduce potential radi o interference to other us ers, the antenna type and its gain should b e chosen so that the equivalent subtropical radia t ed power (EIRP) is not more than required for successful communicati on. T able 1 lists the supported external 2.4- and 5-GHz antennas. Antenna Configurations T wo antenna configurations are av[...]

12 Power War n in g Installation of the equipme nt must comply with local and national electrical codes. Statement 1074 War n in g This equipment must b e externally grounded using a c ustomer -supplied ground wire before power is applied . Contact the appropriate electrical inspection autho rity or an electrician if you are uncertain that suitable[...]

13 War n in g Connect the unit only to DC power source that complies with the Safety Extra-Low V oltage (SEL V) requirements in IEC 60950 based safety standards Statement 1033 • Internal 6 ampere-hour battery The access point can be connected to more than one power source. The access point detects ava ilable input sources and switches to the p re[...]

14 Caution When the a ccess point is installed outdoors or in a wet or damp location, the AC branch circuit that is powering the access point sh ould be provided with ground fault protection (GFCI), as required by Article 210 of the National Electrical Code (NEC). Three AC power cord options are available: • 40-ft (12.2-m) power cord for light po[...]

15 Cable Option The factory-orderable cable option provides a cabl e modem a nd Power -over -Cable capabilities for th e access point for high-speed data tr ansfer and Internet access. When the cable option is insta lled, the access point uses its F-type cable connection to re cei ve both data and power . Data is passed between wireless clients on [...]

16 RAPs, each one parenting the same or different wir el ess networks. There can be more than one RAP for the same mesh network for redundancy . RAPs and MAPs can support wireless clients on the 2.4-GHz band. When the access point does not ha ve a wired Ethernet connection to the controller (through a swi tch), the radio role is called a MAP . Th e[...]

17 Figure 5 P o int-to-P oint Bridging Example Point-to-Multipoint Bridging The access points can be used as a RAP to connect multiple remote MAPs with their a ssociated wired networks. By default this capability is turned-off fo r all access points. T o s upport Ethernet bri dging, you must enable bridging on the controller for each access point. [...]

18 Mesh Network The access point is typically deployed in a mesh ne twork configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller . Othe r remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network. In[...]

19 Layer 3 Network Operation The access points support Layer 3 network operat ion. Access points and controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through large networks. Layer 3 operation is scalable and recommended by Ci sco. Fig ure 8 illustrates a typical Layer -3 wireless network configuration cont[...]

20 Site Surveys Cisco recommends that you perform a si te survey before installing the equipment. A site survey reveals problems that can be resolved befo re the network is operational. Beca use 802.11a is unlicensed, there may be sources of interf erence from other 802.11 a wireless devices (especially in multi-tenant buildings) that could deg rad[...]

21 T o av oid receiver damage and PER deg radation, you can use one of the following techniques: • Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation. Note These distances assume free space path loss and are conservativ e estimates. Required separation dist[...]

22 Before You Begin War n in g Read the installation instru ctions before connecting the sy stem to the power source. Statement 1004 Before you begin the installation p rocess: • Become familiar with the procedur es for mounting the access point. • Become familiar with the access poi nt connections (Figure 1 on page 7, Figure 2 on page 8, and F[...]
