Preparing the AP for Installation

Before mounting and deploying your access point, perform a site survey to determine the best installation location. You will need the following information about your wireless network:

• Access point locations.
• Access point mounting options: below a suspended ceiling, on a flat horizontal surface, or on a desk top.

ℹ️ Additional mounting hardware may be required for mounting above a suspended ceiling. See "Mounting the Access Point" section on page 15.

• Access point power options: 802.3at (PoE+) via Cisco Power Injector AIR-PWRINJ6= or 802.3af via Cisco Power Injector AIR-PWRINJ5=.

ℹ️ If 802.3af is used, both 2.4 GHz and 5 GHz radios will be reduced to 1x1, Ethernet will be downgraded to 1 GbE, and the USB port will be off.

• Operating temperature:
• For 9120AXI model: 32°–122°F (0°–50°C).

ℹ️ When installing the 9120AXI in environments between 104°–122°F (>40°–50°C), configure the AP for 2x2 on both 2.4 GHz and 5 GHz radios, 1GbE Ethernet, and ensure no load on the USB port.

• For 9120AXE and 9120AXP models: -4°–122°F (-20°–50°C).

Cisco recommends creating a site map showing access point locations to record device MAC addresses for network planning and management.

Installation Overview

Installing the access point involves these operations:

1. Performing a Pre-Installation Configuration, page 13 (optional).
2. Mounting the Access Point, page 15.
3. Grounding the Access Point, page 17.
4. Preparing the AP for Installation, page 12.

Performing a Pre-Installation Configuration

These procedures ensure expected access point installation and initial operation. This procedure is optional.

ℹ️ If your network controller is properly configured, you can install the access point in its final location and connect it to the network. See the "Deploying the Access Point on the Wireless Network" section on page 19 for details.

Figure 5: Pre-Installation Configuration Setup

Diagram illustrates the pre-installation configuration setup, showing a Controller, Layer 3 devices, and Cisco Aironet access points connected.

Steps for Pre-Installation Configuration:

1. Ensure the Cisco Wireless Controller DS port is connected to the network. Use the appropriate Cisco Wireless Controller guide for CLI or web-browser interface procedures.
2. Ensure access points have Layer 3 connectivity to the Cisco Wireless Controller Management and AP-Manager Interface.
3. Configure the switch to which the access point will attach. Refer to the Cisco Wireless Controller Configuration Guide for your release.
4. Set the Cisco Wireless Controller as the master so new access points join it.
5. Ensure DHCP is enabled on the network; the access point must receive its IP address via DHCP.

ℹ️ An 802.11ax Cisco AP receives an IP address from the DHCP server if a default router (gateway) is configured on the server and the gateway ARP is resolved.

6. CAPWAP UDP ports must not be blocked.
7. The access point must be able to find the controller's IP address using DHCP, DNS, or IP subnet broadcast. This guide details the DHCP method. Refer to product documentation for other methods, including "Configuring DHCP Option 43" on page 23.

ℹ️ A gigabit Ethernet (GbE) link is required to prevent the Ethernet port from becoming a bottleneck, as wireless traffic speeds exceed 10/100 Ethernet port speeds.

8. Apply power to the access point. See Grounding the Access Point, page 17.

As the AP connects to the controller, LEDs cycle through green, red, and blue (up to 5 minutes).

ℹ️ If the AP remains in this mode for over five minutes, it cannot find the Master Cisco Wireless Controller. Check the connection between the AP and the controller, ensuring they are on the same subnet.

9. If the AP shuts down, check the power source.
10. After finding the controller, the AP attempts to download new OS code if versions differ. The Status LED blinks blue during this process.
11. If OS download is successful, the AP reboots.
12. Configure the access point as required using the controller CLI, GUI, or Cisco Prime Infrastructure for 802.11ac network settings.
13. If pre-installation configuration is successful, the Status LED turns green. Disconnect the AP and mount it at its intended location.
14. If the AP does not indicate normal operation, turn it off and repeat pre-installation configuration.

ℹ️ When installing a Layer 3 AP on a different subnet than the controller, ensure a DHCP server is reachable and the subnet has a route back to the controller. Ensure the route back has UDP ports 5246 and 5247 open for CAPWAP. Allow IP packet fragments and use static 1-to-1 NAT if address translation is used (Port Address Translation is not supported).

Mounting the Access Point

Cisco Catalyst 9120AX series access points can be mounted in several configurations: on a suspended ceiling, a hard ceiling or wall, an electrical or network box, or above a suspended ceiling.

For mounting instructions, visit: http://www.cisco.com/c/en/us/td/docs/wireless/access_point/mounting/guide/apmount.html

Table 2: Brackets and Clips for Mounting the AP

Figure 6: Locking the AP to the Bracket

Diagram shows the position of the hasps for locks on the back of the 9120AXI model.

Grounding the Access Point

⚠️ Only trained and qualified personnel should install, replace, or service this equipment. Statement 1030

Grounding is not always required for indoor installations. However, for C9120AXE or C9120AXP models with external antennas placed outdoors, grounding the AP before connecting power is mandatory. Refer to "List of External Antennas Supported on C9120AXE and C9120AXP" for supported antennas.

Required tools and materials:

• Copper ground wire (minimum 18AWG)
• Grounding O-ring connector (M3 stud size)
• Crimping tool
• Wire stripping tool
• Phillips screwdriver (Number 2)

⚠️ To reduce electric shock risk, connect the equipment chassis to permanent earth ground during normal use. Statement 445

Grounding Steps:

1. Find a suitable building grounding point near the AP.
2. Connect the ground wire to the building grounding point.
3. Route the other end of the ground wire to the AP.
4. Use the wire stripping tool to strip the ground wire to 0.22 inches (5.56mm).
5. Insert the ground wire into the open end of the connector.

Figure 7: Grounding O-ring connector

Diagram shows a grounding O-ring connector.

6. Crimp the connector's wire receptacle carefully around the wire for a proper mechanical connection.
7. Locate the chassis ground connector on the AP.

Figure 8: Grounding Label on the Head of the 9120AXE and 9120AXP Models

Diagram shows the grounding label on the AP.

8. Secure the connector to the AP using the connector's washer and screw. Tighten screws carefully until the connector is held firmly to the chassis; do not overtighten.

⚠️ Connect the power cable to the AP after it is grounded.

The outdoor antenna connection must be grounded per ANSI/NFPA 70 (NEC), Article 800, Grounding of Outer Conductive Shield of a Coaxial Cable.

⚠️ To reduce electric shock risk, the shield of the coaxial cable must be connected to the building earth. Statement 1094

Powering the Access Point

For C9120AXE or C9120AXP models, ensure external antennas are connected before applying power.

The AP can be powered via Power-over-Ethernet (PoE) using:

• 802.3at (PoE+): Any 802.3at (30.0 W) compliant switch port or Cisco Power Injector AIR-PWRINJ6=.
• 802.3af: Any 802.3af (15.4 W) compliant switch port or Cisco Power Injector AIR-PWRINJ5=.

ℹ️ If 802.3af is used, 2.4 GHz and 5 GHz radios are reduced to 1x1, Ethernet is downgraded to 1 GbE, and the USB port is off.

Configuring and Deploying the Access Point

This section covers connecting the access point to a controller. Configuration occurs on the controller; refer to the Cisco Wireless Controller Configuration Guide for details.

The Controller Discovery Process

• The controller must be running release 8.9.111.0 or later to support 9120AX series APs. See the AP data sheet for more information.
• Access point names with spaces cannot be edited or queried via controller CLI.
• Ensure the controller's time is set correctly; an invalid certificate time may prevent the AP from joining.

Access points must be discovered by a controller to become active network components. Discovery processes include:

• Locally stored controller IP address discovery: If previously joined, AP stores primary, secondary, and tertiary controller IPs in non-volatile memory (priming). See "Performing a Pre-Installation Configuration" on page 13.
• DHCP server discovery: Uses DHCP option 43 to provide controller IPs. See "Configuring DHCP Option 43" on page 23.
• DNS discovery: AP discovers controllers via DNS by resolving CISCO-CAPWAP-CONTROLLER.localdomain.

Deploying the Access Point on the Wireless Network

After mounting the AP, follow these steps:

1. Connect and power up the access point.
2. Observe the access point LED (see "Checking the Access Point LEDs" section on page 21 for descriptions).
• On power-up, the LED sequence (green, red, off) indicates the power-up and join process. A chirping green LED indicates the AP has joined a controller and clients are associated; solid green means clients are associated.
• If the LED is off, the AP is likely not receiving power.
• If the LED blinks sequentially for over 5 minutes, the AP cannot find its controller. Check connections and subnet configuration. Ensure a DHCP server is on the same subnet if the AP is not. See "Configuring DHCP Option 43" on page 23.
3. Reconfigure the Cisco Wireless Controller to not be the master.

ℹ️ A master Cisco Wireless Controller should only be used for configuring APs, not in a working network.

Self-Identifying Antennas

The 9120AXE and 9120AXP APs support Self-Identifying Antennas (SIAs). SIAs have a purple band or label indicating the connector, which should be connected to dual-band port A on the AP (also identified by purple text around the RP-TNC connector). Other RP-TNC ports have standard orange text.

⚠️ Always connect external antennas to 9120AXE and 9120AXP models before powering up. Enabling radios without antennas can damage the AP.

When an SIA is connected, the AP reads its EEPROM to automatically configure antenna gain and beam-width. Legacy antennas require manual configuration in the wireless controller.

Checking the Access Point LEDs

The access point status LED location is shown in Figure 2. LED status colors may vary slightly between units, which is normal. Intensity can be adjusted via the controller.

Table 3: LED Status Indications

Miscellaneous Usage and Configuration Guidelines

Using the Mode Button

The Mode button can be used to:

• Reset the AP to default factory-shipped configuration.
• Clear the AP internal storage, including all configuration files.

To use the mode button: Press and hold the button during the AP boot cycle until the Status LED changes to Blue. A seconds counter will appear on the AP console.

• Reset to factory defaults (less than 20 seconds press): Clears AP configuration files, resetting passwords, WEP keys, IP address, and SSID.
• Clear internal storage (20-60 seconds press): Clears AP internal storage, including configuration files and regulatory domain configuration. The AP status LED changes from Blue to Red, and storage is cleared.

Pressing the button for over 60 seconds is considered faulty, and no changes are made.

Troubleshooting the Access Point to Cisco Controller Join Process

ℹ️ Ensure your controller runs software Release 8.9.111.0 or later, as per the Cisco Wireless Solutions Software Compatibility Matrix.

Access points may fail to join a controller due to RADIUS authorization, missing self-signed certificates, mismatched regulatory domains, etc.

Controller software can send CAPWAP errors to a syslog server for analysis without needing debug commands.

The controller collects join-related information for each AP sending a discovery message. This information is maintained until the controller reaches its maximum capacity.

An AP sends syslog messages to 255.255.255.255 by default for new deployments or after configuration resets. A DHCP server can be configured with option 7 to direct syslog messages to a specific IP address.

When an AP joins a controller, the controller sends its global syslog server IP address. This can be updated via controller CLI commands (e.g., config ap syslog host global syslog_server_IP_address or config ap syslog host specific Cisco_AP syslog_server_IP_address) or when the AP connects to a new controller.

Important Information for Controller-based Deployments

• APs communicate only with Cisco wireless controllers.
• APs do not support Wireless Domain Services (WDS); controller provides equivalent functionality.
• CAPWAP requires Layer 3 discovery via DHCP, DNS, or IP subnet broadcast.
• The AP console port is for monitoring and debug; configuration commands are disabled when connected to a controller.

Configuring DHCP Option 43

DHCP Option 43 provides controller IP addresses to APs for discovery and joining. The example below is for a Windows 2003 Enterprise DHCP server.

ℹ️ DHCP Option 43 is limited to one AP type per DHCP pool. Configure a separate pool for each AP type.

The 9120AX series uses the type-length-value (TLV) format for DHCP Option 43. DHCP servers must return the option based on the AP's DHCP Vendor Class Identifier (VCI) string: Cisco AP C9120AX.

TLV format: Type (0xf1), Length (Number of controller IPs * 4), Value (Controller management interface IPs in hex).

Example Cisco IOS CLI command for DHCP scope: option 43 hex f1080a7e7e020a7f7f02 (for two controllers).
