The Aironet 1815w access point is abbreviated as AP in this document.

2 About the Access Point

The Cisco Aironet 1815w access point is an 802.11 a/b/g/n/ac (Wave 2) access point, with internal antennas.

The Cisco Aironet 1815w AP can be vertically mounted on a wall or on a standard junction box. Physical security is offered with the included Torx screw and the option to add a Kensington lock.

The AP supports 2.4 GHz 2x2 802.11 b/g/n MU-MIMO and 5 GHz 2x2 802.11 a/n/ac (Wave 2) MU-MIMO applications simultaneously.

6 Preparing the AP for Installation

Before you mount your access point, we recommend that you perform a site survey (or use the site planning tool) to determine the best location to install your access point.

You should have the following information about your wireless network available:

•Access point locations.

•Access point mounting options: vertical wall-mounting only.

•Access point power options. See the “Powering the Access Point” section on page 28

Cisco recommends that you make a site map showing access point locations so that you can record the device MAC addresses from each location and return them to the person who is planning or managing your wireless network.

7 Installation Overview

Installing the access point involves these operations:

Step 1 Performing a Pre-Installation Configuration, page 12 (optional)

Step 2 Mounting the Access Point, page 15

Step 3 Powering the Access Point, page 28

Step 4 Configuring and Deploying the Access Point, page 29

11

8 Performing a Pre-Installation Configuration

The following procedures ensure that your access point installation and initial operation go as expected for a Cisco wireless controller-based (i.e. having a physical controller device) network. This procedure is optional.

Note Performing a pre-installation configuration is an optional procedure. If your network controller is properly configured, you can install your access point in its final location and connect it to the network from there. See the “Deploying the Access Point on the Wireless Network” section on page 31 for details.

The pre-installation configuration setup is illustrated in Figure 4.

Layer 3 devices

To perform pre-installation configuration, perform the following steps:

Step 1 Make sure that the Cisco wireless LAN controller DS port is connected to the network. Use the CLI, web-browser interface, or Cisco Prime Infrastructure procedures as described in the appropriate Cisco wireless LAN controller guide.

a.Make sure that access points have Layer 3 connectivity to the Cisco wireless LAN controller Management and AP-Manager Interface.

b.Configure the switch to which your access point is to attach. See the Cisco Wireless LAN Controller Configuration Guide for the release you are using, for additional information.

c.Set the Cisco wireless LAN controller as the master so that new access points always join with it.

d.Make sure DHCP is enabled on the network. The access point must receive its IP address through DHCP.

e.CAPWAP UDP ports must not be blocked in the network.

f.The access point must be able to find the IP address of the controller. This can be accomplished using DHCP, DNS, or IP subnet broadcast. This guide describes the DHCP method to convey the controller IP address. For other methods, refer to the product documentation. See also the “Configuring DHCP Option 43” section on page 38 for more information.

Note The access point requires a Gigabit Ethernet (GbE) link to prevent the Ethernet port from becoming a bottleneck for traffic because wireless traffic speeds exceed transmit speeds of a 10/100 Ethernet port.

Step 2 Apply power to the access point. See Powering the Access Point, page 28.

a.As the access point attempts to connect to the controller, the LEDs cycle through a green, red, and amber sequence, which can take up to 5 minutes.

Note If the access point remains in this mode for more than five minutes, the access point is unable to find the Master Cisco wireless LAN controller. Check the connection between the access point and the Cisco wireless LAN controller and be sure that they are on the same subnet.

b. If the access point shuts down, check the power source.

13

c.After the access point finds the Cisco wireless LAN controller, it attempts to download the new operating system code if the access point code version differs from the Cisco wireless LAN controller code version. While this is happening, the Status LED blinks amber.

d.If the operating system download is successful, the access point reboots.

Step 3 Configure the access point if required. Use the controller CLI, controller GUI, or Cisco Prime Infrastructure to customize the access-point-specific 802.11ac network settings.

Step 4 If the pre-installation configuration is successful, the Status LED is green indicating normal operation. Disconnect the access point and mount it at the location at which you intend to deploy it on the wireless network.

Step 5 If your access point does not indicate normal operation, turn it off and repeat the pre-installation configuration.

Note When you are installing a Layer 3 access point on a different subnet than the Cisco wireless LAN controller, be sure that a DHCP server is reachable from the subnet on which you will be installing the access point, and that the subnet has a route back to the Cisco wireless LAN controller. Also be sure that the route back to the Cisco wireless LAN controller has destination UDP ports 5246 and 5247 open for CAPWAP communications. Ensure that the route back to the primary, secondary, and tertiary wireless LAN controller allows IP packet fragments. Finally, be sure that if address translation is used, that the access point and the Cisco wireless LAN controller have a static 1-to-1 NAT to an outside address. (Port Address Translation is not supported.)

9 Mounting the Access Point

Cisco Aironet 1815w access points can be mounted directly on the wall, to numerous global wall junction standards.

Mounting the AP directly on a Wall

To mount the AP on a wall, follow these steps:

Step 1 Fasten the wall-mount bracket (AIR-AP-BRACKET-W3) to the wall, using two M3.5X32mm screws. Ensure that the side having the Mount Arrows Up label is facing outwards, and the bracket is oriented vertically as indicated by the arrows. See Figure 11.

The wall-bracket dimensions are given in Figure 12.

Step 2 Connect the power and network cables to the AP.

If you are unable to connect a PoE cable to the port on the back of the AP, then:

a.On the back of the AP, use an RJ45 jumper cable to connect the PoE port to the Pass-Through port. This jumper cable is available as part of the spacer kit AIR-AP1815W-KIT=.

b.Connect the PoE supply cable to the Pass-Through port on the base of the AP.

This connection sends power internally from the Pass-Through port on the base, to the Pass-Through port on the back, and then though the jumper cable into the PoE port on the back.

Step 3 Mount the AP onto the wall-mount bracket. For this, align the AP with the bracket and then offset the AP around ¼ inch above the bracket.

Step 4 Fasten the AP to the bracket using the M2 x 5.5mm Torx security screw. Cover it with the mylar label.
