The PoE-in port should be used to power the access point and connect to a WLC. The LAN port will be used for Ethernet Bridging and Daisy chaining. The 1532 can be powered either by PoE-in, using a PoE injector, or by 48 VDC.
Scope, Objectives, and Expectations Getting Started with the AP 1532 1 Console/Reset 2 Solar Shield Screw Holes The Console port is located on the side of the Access Point, covered by a plastic cap. There is a reset button located under the cap as well. The Solar Shield Screw holes are used to secure the Solar Shield add-on, if the access point needs to be painted to match its environment. 1 LED The LED can be used to determine the status of the access point.
Scope, Objectives, and Expectations Getting Started with the AP 1532 1 Note Flexible Antenna Port (N Type) Connectors The Flexible Antenna Port Connectors are only present on the 1532E. The AP 1532E has four antenna ports with N-Type connectors, two at the top of the access point and two at the bottom of the access point. When in Dual band mode, the bottom antenna ports (port 1 and port 2) are used for both 2.4 GHz and 5 GHz.

Scope, Objectives, and Expectations Flexible Antenna-Port Configuration Note For more details please visit the 1532 Hardware Installation guide: http://www.cisco.com/en/US/docs/ wireless/access_point/1530/installation/guide/1530hig.html Flexible Antenna-Port Configuration There are two terms that are used when referring to Antenna Band Mode Configurations: • Dual Antenna Band Mode – The bottom two ports, port 1 and port 2, are used for dual band 2.4 GHz/5 GHz Dual Radiating Element (DRE) antennas.
Scope, Objectives, and Expectations Flexible Antenna-Port Configuration Note Misconfiguring the Antenna Band Mode can strand a mesh AP, please make sure your physical antennas are properly configured before changing the Antenna Band Mode. A warning message will be displayed to confirm the changes.
Scope, Objectives, and Expectations Daisy Chaining with AP 1532 Daisy Chaining with AP 1532 One of the key features of the 1532 access point is the ability to “daisy chain” access points while they are operating as Mesh APs (MAPs). By “daisy chaining” MAPs, customers can either operate the access points as a serial backhaul, allowing different channels for uplink and downlink access thus improving backhaul bandwidth, or to extend universal access across a mesh network.
Scope, Objectives, and Expectations Enabling Daisy Chaining using the WLC GUI • The uplink daisy-chained AP is considered the Master AP, the connected AP is considered the Slave AP. • The Master AP must be configured as Mesh AP (MAP). • The Slave AP must be configured either as Bridge Mode Root AP or a local/Flexconnect AP, but not as a Mesh AP. If the Slave AP is configured as a MAP there is risk of a layer 2 bridging loop.
Scope, Objectives, and Expectations Enabling Daisy Chaining using the WLC CLI Daisy chaining should only be enabled on a Slave AP that is configured as a Bridge Mode Root Access Point, for all other daisy-chaining configurations, daisy chaining does not need to be enabled. To enable Daisy Chaining from the WLC GUI, navigate to the Wireless > Access Point >AP NAME > Mesh tab, and then check the Daisy Chaining check box.
Scope, Objectives, and Expectations Enabling Daisy Chaining Using the AP CLI To enable Ethernet Bridging on the Master MAP, issue the command: (Cisco Controller) >config ap bridging [enable/disable] Daisy chaining should only be enabled on a Slave AP that is configured as a Bridge Mode Root Access Point, for all other daisy chaining configurations, daisy chaining does not need to be enabled.
Scope, Objectives, and Expectations Bridge Group Name Note When the preferred parent is entered, no other mesh configurations can be submitted at the same time. You must apply the changes, wait 90 seconds, then other mesh changes can be made. Note To clear the Preferred Parent text box, the value "none" must be entered then submitted.
Scope, Objectives, and Expectations Deployment Modes Setting a BGN Using the WLC CLI BGN can also be set via the WLC CLI, by issuing the command: Cisco Controller) >config ap bridgegroupname set MESH-BGN AP_NAME Deployment Modes Bridge Mode Deployment This is your typical mesh configuration. RAPs have wired connections to their controller, the MAPs have wireless connections to their controller. MAPs communicate among themselves and back to the RAP using wireless connections over the 802.
Scope, Objectives, and Expectations Deployment Modes ◦Backhaul data rate set to auto. ◦No more than 4 Mesh hops. ◦To maximize backhaul data rates, allow client access on only the 2.4 GHz radio. Local/Flexconnect Deployment • Use the AP 1532 like an indoor AP. • Support for local mode features: ◦RRM on both 2.4 GHz and 5 GHz bands. ◦AP SSO ◦CAC support for VoIP. Daisy Chaining as a Serial Backhaul The 1532 Daisy chaining feature can be used to provide a serial backhaul mesh.
Scope, Objectives, and Expectations Deployment Modes High gain directional antenna should be used in typical serial backhaul deployments. In addition, "Preferred Parent" configurations should be used to create serial backhaul mesh networks. • Only 1532s in Bridge Mode can utilize this configuration. • Master MAP & Slave MAP are operating on different 5 GHz channels to maximize throughput across the mesh link. • BGN configuration and the Preferred Parent command are recommended to maintain the mesh tree.
Scope, Objectives, and Expectations Autonomous Software • The Master MAP must have Ethernet bridging enabled. Autonomous Deployment • 1532s are point-to-point bridging replacements for 1310/1410. • Root Bridges/Non-root Bridges can bridge on either the 2.4 GHz radio or the 5 GHz radio. • Directional antennas should be used to maximize bridging distance. • New Install mode that flashes the LEDs to denote link quality.
Scope, Objectives, and Expectations Range and Capacity Calculator If the AP has already joined a WLC, you need to convert the image using the following command from the AP console: AP#archive download-sw /force-reload /overwrite tftp:/// AP#archieve download-sw /force-reload /overwrite tftp://10.0.0.5/ap1g3-k9w7-tar Note that the k9w7 denotes the autonomous image. The autonomous image can be found at cisco.com.
Scope, Objectives, and Expectations Design and Planning with the 1532 Access Point • Mesh: AP-to-AP Backhaul Distance Capability should be - 2x AP-to-Client. • WiFi Network Planning Involves: ◦Site Survey to Identify: AP Location & Height, Line-of-Sight (LoS)/Partial LoS, Interference, Access to wired backhaul (i.e. Max # Hops). ◦Knowledge of the client type (Smart Phones, Tablets, Laptops). ◦Weakest Link typically would be the Uplink on a Smart Phone.
Scope, Objectives, and Expectations Troubleshooting Assumptions: • Height: APs are at 33 Ft (10 m), and Client at 3.3 ft (1 m) • Throughput: > 1 Mbps • Decreasing AP-AP distance improves consumer experience (throughput, latency). • Near LoS suburban. For Less LoS Scenarios; Reduce Distance Assumptions. • Flat Terrain Environment. • Comparing the 1532I to the 1532E with AIR-ANT2547V-N dual band antennas. The 1532E with high-gain antennas can reach much greater AP to AP distances.
Scope, Objectives, and Expectations Troubleshooting Type LED State AP Action Boot loader warnings Blinking AMBER Configuration recovery in progress (MODE button pushed for 2 to 3 seconds) RED Ethernet failure or image recovery (MODE button pushed for 20 to 30 seconds) Blinking GREEN Image recovery in progress (MODE button released) RED DRAM memory test failure. Blinking RED and AMBER FLASH file system failure. Blinking RED and off Environment variable failure.
