1 About this Guide
This guide provides instructions on how to install your Cisco Catalyst 9117AX series access points and provides links to
resources which can help you configure the access point. This guide provides mounting instructions and limited
troubleshooting procedures.
The 9117AX series access point is referred to as access point or AP in this document.
2 About the Access Point
The Cisco Catalyst 9117AX Series wireless access point is a dual band, dual concurrent, enterprise 802.11ax AP. This
AP series offers integrated antenna options, designed to use both 2.4 GHz and the 5 GHz bands. This access point
supports a greater overall High Density Experience (HDX) which provides a more predictable performance for advanced
applications such as 4K or 8K video, high-density high-definition collaboration applications, all-wireless offices and
Internet-of-Things (IoT). The access point supports full interoperability with leading 802.11ax and 802.11ac clients, and
supports a mixed deployment with other access points and controllers.
A full listing of the access point's features and specifications are provided in the Cisco Catalyst 9117AX Series Access

Spatial Reuse (also known as BSS coloring) allows APs and their clients to differentiate between BSSs, thus
permitting more simultaneous transmissions.
Built-in BLE radio (Bluetooth 5.0)
mGig Ethernet (1G,2.5G, 5G, and 100M)
Supports up to 500 Wi-Fi devices
New power savings mode called Target-Wakeup-Time (TWT), allows the client to stay asleep and wake up only at
pre-scheduled (target) times to exchange data with the AP. This allows for significant energy savings for
battery-operated devices.
Cisco Digital Network Architecture (DNA) support enables Cisco Connected Mobile Experiences, Apple FastLane
and Cisco Identity Services Engine
Cross-AP Noise Reduction, a Cisco innovation that enables APs to intelligently collaborate in real time about RF
conditions so that users connect with optimized signal quality and performance.
Optimized AP Roaming for ensuring that client devices associate with the AP in their coverage range that offers the
fastest data rate available.
Cisco ClientLink 4.0 technology for improved downlink performance to all mobile devices, including one-, two-, and
three-spatial-stream devices up to 802.11ac Wave 1 and Wave 2. The technology also improves battery life on
mobile devices.
Cisco CleanAir technology enhanced with 160MHz channel support. CleanAir delivers proactive, high-speed
spectrum intelligence across 20-, 40-, and 80-, and 160-MHz-wide channels to combat performance problems
arising from wireless interference.
MIMO equalization capabilities, which optimize uplink performance and reliability by reducing the impact of signal
fade.
The AP supports both Cisco Mobility Express and lightweight deployments (using Cisco Wireless LAN controllers). The
AP also supports the following operating modes:
Local—This is the default mode for the Cisco AP. In this mode, the AP does not serve clients.
Flexconnect—Flexconnect mode for the Cisco AP.
Monitor—This is the monitor-only mode for the Cisco AP.
Sniffer—In the wireless sniffer mode, the AP starts sniffing the air on a given channel. It captures and forwards all the
packets from the clients on that channel to a remote machine that runs Airopeek or Wireshark (packet analyzers for
IEEE 802.11 wireless LANs). This includes information on the time stamp, signal strength, packet size, etc.
Note In the sniffer mode, the server to which the data is sent should be on the same VLAN as the wireless
controller management VLAN otherwise an error will be displayed.

7 Performing a Pre-Installation Configuration
The following procedures ensure that your access point installation and initial operation go as expected. 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 15 for details.
The following Pre-Installation Configuration procedure given does not include configuring Link Aggregation. For
information on configuring Link Aggregation, see the Cisco Wireless LAN Controller Configuration Guide, Release 8.2, at
this URL:
http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-2/config-guide/b_cg82.html
The pre-installation configuration setup is illustrated in Figure 3.

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 WCS 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.
Note A Wave 2 Cisco AP will be assigned an IP address from the DHCP server only if a default router (gateway)
is configured on the DHCP server (enabling the AP to receive its gateway IP address) and the gateway
ARP is resolved.
This is not applicable to Wave 1 Cisco APs.
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 20 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 14.
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.
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.)
