C9115AXI-E Description
C9115AXI-E is a Cisco Catalyst 9115 Series indoor Wi-Fi 6 access point for controller-based wireless access in the E regulatory domain. The model uses the C9115AXI internal-antenna design with dual-band 2.4 GHz and 5 GHz radios, 4x4 MIMO with four spatial streams, and a 100/1000/2500 Multigigabit Ethernet RJ-45 uplink. Cisco documentation lists it for Catalyst 9800 Series and AireOS controller environments with Cisco Unified Wireless Network Software Release 8.9 or later or Cisco IOS XE Software Release 16.11 or later, and its PoE behavior supports full 4x4 radio operation, 2.5G Ethernet, USB, and 20.4W maximum draw on 802.3at while reducing features on 802.3af power.

Application Scenarios
C9115AXI-E fits indoor Wi-Fi 6 refresh work where the deployment country maps to the -E regulatory domain and the design uses Cisco Catalyst 9115AXI internal antennas.
Use C9115AXI-E for carpeted office, education, or campus areas where the AP should follow the ceiling-oriented AXI internal-antenna model rather than an external antenna layout.
C9115AXI-E suits access-layer upgrades that pair Cisco wireless controller discovery with 802.3at PoE so the AP can run the documented 4×4 radio, 2.5G uplink, and USB profile.

- In a C9115AXI-E vs C9115AXE-E comparison, the confirmed difference is the antenna path: C9115AXI-E is the integrated internal-antenna AP, while C9115AXE-E is the external-antenna AP.
- The C9115AXI-E difference matters when the RF plan expects a ceiling-focused AXI body; C9115AXE-E belongs in the comparison when RP-TNC external antennas are part of the design.
- For buyers deciding which model to choose, keep the same -E suffix for regional compliance and choose between C9115AXI-E and C9115AXE-E by antenna hardware. C9115AXI-H is included as an additional same-family comparison point.
Selection Guide
1. Anchor the order to the -E approval
Select C9115AXI-E only when Cisco compliance resources support the -E regulatory domain for the installation country.
2. Choose AXI for integrated antenna designs
Use the AXI model when the WLAN survey calls for the internal dual-band antenna layout documented for the Catalyst 9115AXI family.
3. Move to AXE only for external antenna requirements
Specify C9115AXE-E instead when the deployment needs external antenna connectors or directional antenna planning confirmed for the AXE family.
4. Plan power for full feature operation
Reserve 802.3at PoE or a Cisco-supported injector when the quote requires 4×4 radios, 2.5G Ethernet, and USB availability.
Ordering Checklist
|
Procurement Area |
Required Check |
Risk Controlled |
|---|---|---|
|
Regulatory domain |
Match C9115AXI-E to the target country approval record |
The -E suffix is not interchangeable with other C9115AXI domains |
|
Antenna family |
Confirm AXI internal antennas rather than AXE external antenna hardware |
The two model families use different RF planning assumptions |
|
Controller software |
Check Cisco Unified Wireless Network 8.9 or later or Cisco IOS XE 16.11 or later |
The AP must join a supported Cisco wireless controller for service |
|
Mounting choice |
Select AIR-AP-BRACKET-1 or AIR-AP-BRACKET-2 for the installation surface |
Missing bracket selection can delay physical deployment |
|
Country compliance |
Recheck Cisco compliance resources before finalizing regional rollout quantities |
Regulatory approval can vary by country even within the same AP family |
