C9115AXI-A Description
C9115AXI-A is a Cisco Catalyst 9115AX Series indoor Wi-Fi 6 access point with integrated internal antennas for controller-managed wireless access. It belongs to the C9115AXI regulatory-domain ordering family and is used for indoor campus, branch, and distributed wireless deployments that need 802.11ax access with 4x4 MIMO and four spatial streams. Cisco documentation confirms a multigigabit Ethernet uplink, RJ-45 console, USB 2.0, controller-based operation with Cisco Catalyst 9800 Series and AireOS controller options, and PoE operation where 802.3at enables the full 4x4 radio profile, 2.5G link, USB, and 20.4W maximum PoE draw.

Application Scenarios
C9115AXI-A fits indoor WLAN refresh projects where the AP should use Cisco’s Catalyst 9115AXI internal-antenna body and ceiling-oriented coverage rather than an external-antenna design.
Use C9115AXI-A for deployments where the access point will discover and join a supported Cisco wireless controller through CAPWAP after network addressing and controller reachability are in place.
C9115AXI-A suits access-layer upgrades where 802.3at PoE is planned for the full 4×4 radio and 2.5G uplink profile, while 802.3af operation is acceptable only for the Cisco-listed reduced feature mode.

- In a C9115AXI-A vs C9115AXE-A comparison, the main difference is the antenna path: C9115AXI-A uses integrated internal antennas, while C9115AXE-A is the external-antenna model.
- The C9115AXI-A difference for mounting review is the ceiling-oriented internal-antenna coverage plan; C9115AXE-A is the comparison SKU when the RF design needs external or directional antennas.
- For buyers deciding which model to choose, keep C9115AXI-A on the BOM when the site standard is an internal-antenna 9115AXI AP and use C9115AXE-A only when the antenna plan requires the AXE hardware family. C9115AXI-H is included as an additional same-family comparison point.
Selection Guide
1. Match the antenna model to the RF design
Select C9115AXI-A when the deployment calls for Cisco’s internal-antenna Catalyst 9115AXI AP and does not require external antenna connectors.
2. Use C9115AXE-A for external antenna work
Choose C9115AXE-A instead when the site design depends on approved external or directional antennas rather than the integrated AXI antenna layout.
3. Confirm PoE feature mode before quote review
Plan 802.3at PoE when the project needs the full 4×4 radio profile, 2.5G link, and USB support; treat 802.3af as a reduced-feature power path.
4. Validate controller and country fit
Check the supported wireless controller release and the -A regulatory-domain approval for the installation country before ordering.
Ordering Checklist
|
Procurement Area |
Required Check |
Risk Controlled |
|---|---|---|
|
Exact AP PID |
Confirm C9115AXI-A rather than another C9115AXI-x suffix |
Cisco uses x as the regulatory-domain placeholder and country approval must match the order |
|
Antenna model |
Verify that the design needs AXI internal antennas and not AXE external antennas |
The AXI and AXE families differ in antenna hardware and RF planning use |
|
PoE source |
Confirm 802.3at switch power or the appropriate Cisco injector for full feature operation |
Cisco lists reduced radios, 1G link speed, and disabled USB under 802.3af power |
|
Controller readiness |
Confirm Cisco Unified Wireless Network or IOS XE software support on the target controller |
The AP must discover and join a Cisco wireless controller before active service |
|
Mounting hardware |
Choose AIR-AP-BRACKET-1 or AIR-AP-BRACKET-2 according to the mounting surface |
Cisco lists bracket options for ceiling, electrical box, and related mounting cases |
|
Country approval |
Validate the -A suffix through Cisco compliance resources for the deployment location |
Regulatory-domain approval is country-specific and cannot be inferred from a nearby SKU |
