CW9172I Installation Guide
The Cisco Wireless CW9172I is a Tri-band, Tri-radio, enterprise-class, Wi-Fi 7, cloud-managed access point supporting 2.4 GHz, 5 GHz, and the newly opened
unlicensed 6 GHz frequency bands. Designed for moderate-density environments of regional branches, retail and health care, the CW9172I meets the needs of
the most demanding environments. The access point also includes a fourth radio dedicated to optimizing the RF environment and securing the airwaves. The
CW9172I also has an additional Bluetooth Low Energy (BLE) capable radio used for location and other IoT applications. In addition to this, the CW9172I also
has a USB port to support external devices for IoT applications

    NOTE: Blinking Green LED indicates that the device is in site survey mode. Please see the Conducting Site Surveys with MR Access Points for more details. The CW9172I access point may be operated in the “Run Dark” mode for additional security and to reduce the visibility of the access point. In this mode, the LED will not be illuminated.

    • Before you work on any equipment, be aware of the hazards involved with electrical circuitry, and be familiar with standard practices for preventing accidents. • Read the wall-mounting instructions carefully before beginning installation. Failure to use the correct hardware or to follow the correct procedures could result in a hazardous situation to people and damage to the system.

    2. Power over Ethernet supports a maximum cable length of 300 ft (100 m). 3. If being used in a mesh deployment, the AP should have a line of sight to at least two other Meraki devices. A Cisco Partner can help ensure that your AP placement is ideal.
  • Page 14 bracket. Attach the Low Profile Mounting Bracket The access point universal mounting bracket (AIR-AP-BRACKET-1 - included) can be used to install your access point in a wide range of scenarios including wall or solid ceiling or below a drop ceiling. The mount cradle contains a variety of hole patterns that are customized for each installation scenario.
  • Page 15 Note: The T-Rail mount attachment (AIR-AP-T-RAIL-R) has two included screws pre-installed to lock the T-Rail mount to the actual T-Rail so it will not slide back and forth. These two screws are not to be confused with the #6-32 x 1/4 screws in a separate bag for mounting the universal bracket to the T-Rail mount (steps 4 and 5 below) 3.

Align the corresponding holes (A, B, or C) on the mounting bracket over the mounting holes on the ceiling grid clip.Hold the mounting bracket and insert a 6-32 x 1/4 in. screw into each of the four corresponding holes (A, B, or C) and tighten. CW9172I is now ready to be mounted on the drop ceiling.
  • Page 17 To attach the CW9172I AP to the low profile mounting bracket properly, align the access point feet over the keyhole mounting slots on the mounting bracket. Since the cradle is already mounted to the drop ceiling, gently guide the CW9178I AP toward the mounting cradle until it clicks into place. Once the AP is mounted, the Ethernet Cable can be plugged in straight due to the lower recess and the large bay.

    Verify Device Functionality and Test Network Coverage Check LEDs The Power LED should be solid green (or blue, if clients are connected). If it is flashing blue, the firmware is automatically upgrading and the LED should turn green when the upgrade is completed (normally within a few minutes). See the "LED Indicators"...
  • Page 22 Wireless → Configure → Radio Settings → RF Profile → 6 GHz. Change the Channel width setting to Manual to enable 320 MHz. Flex Radio Selection The CW9172I has three client serving Wi-Fi Radios capable of operating in the 2.4, 5 and 6 GHz Frequencies as 2x2 radio chain with 2 spatial streams or as a dual band access point with 2x2:2 in 2.4 GHz and 4x4:4 in 5 GHz.
  • Page 23 WPA3 Support Wi-Fi 7 requires the client to support WPA3 or OWE with Protected Management Frame (PMF) as a mandatory mode of operation for Wi-Fi 7 -i.e. for 11be rates and MLO. The Wi-Fi 7 Access Point is very much backward compatible with the earlier security mechanisms like WPA2, but when a Wi-Fi 7 client connects with a lower security type, it cannot achieve the Wi-Fi 7 functionality.
  • Page 24 OWE Configuration: From the Wireless → Configure → Access Control → Security, Select Opportunistic Wireless Encryption (OWE) Select WPA3 as the Encryption, 802.11w as Required. From Advanced WPA3 settings (Cipher and AKM suite settings), select the cipher as GCMP 256.
  • Page 25 Note: If an SSID is configured to support WPA3 transition mode for Personal across all three frequency bands, then the 2.4 GHz and the 5 GHz frequency will broadcast the SSID with transition mode support. The SSID will not be broadcast in the 6 GHz mode Note: Starting R31 software release, if an SSID is configured to support WPA3 transition mode for Enterprise across all three frequency bands, then the 2.4 GHz and the 5 GHz frequency will broadcast the SSID with transition mode support and the SSID will be broadcasted as WPA3 in the 6 GHz band.

  • Page 26: Basic Troubleshooting

    Note: If the AP is broadcasting at least one of the SSIDs with a lower security type, then the AP will not broadcast 11be information in the Beacon and Probe Response and will function as 11ax.This behaviour is due to change in a future firmware upgrade. Basic Troubleshooting The following steps can be used for troubleshooting basic connectivity issues with your access point.
