C9115AXI-B Description
C9115AXI-B is a Cisco Catalyst 9115 Series indoor Wi-Fi 6 access point with integrated internal antennas for controller-based campus wireless access in the B regulatory domain. The SKU is part of the C9115AXI-x ordering family and is documented for dual-band 2.4 GHz and 5 GHz operation with 4x4 MIMO and four spatial streams, a 100/1000/2500 Multigigabit Ethernet uplink, RJ-45 console access, and USB 2.0. It supports Cisco Unified Wireless Network Software Release 8.9 or later and Cisco IOS XE Software Release 16.11 or later with Catalyst 9800 Series and supported AireOS wireless controllers, while its PoE feature set depends on the negotiated power source: 802.3at enables the full 4x4 radio and 2.5G link profile, and 802.3af reduces radio and uplink capability.

Application Scenarios
C9115AXI-B fits indoor Cisco WLAN refresh projects where the bill of materials must use the -B regulatory-domain suffix and the RF design is based on the Catalyst 9115AXI internal-antenna model.
Use C9115AXI-B for offices, classrooms, and similar interiors where an integrated antenna AP is preferred over cable-managed external antennas or directional antenna placement.
C9115AXI-B suits deployments where the AP will join a Cisco wireless controller and the access switch or injector can supply 802.3at PoE for the listed 4×4 radio, 2.5G uplink, and USB feature profile.

- In a C9115AXI-B vs C9115AXE-B comparison, the table difference is antenna hardware: C9115AXI-B is the integrated internal-antenna AP, while C9115AXE-B is the external-antenna model.
- The C9115AXI-B difference is not the Wi-Fi generation or regulatory suffix; both compared models are Wi-Fi 6 4×4:4 APs with the -B suffix.
- For buyers deciding which model to choose, use the C9115AXI-B comparison to keep the BOM on the internal-antenna 9115AXI family unless the RF plan calls for RP-TNC external antenna connectors. C9115AXI-H is included as an additional same-family comparison point.
Selection Guide
1. Start from the compliance domain
Keep C9115AXI-B on the quote only when Cisco compliance resources map the installation country to the -B regulatory domain.
2. Reserve it for internal-antenna ceiling plans
Use this SKU where the survey expects the 9115I internal antenna pattern and no RF cable or antenna connector accessories are planned.
3. Use AXE for connector-based RF designs
Compare against C9115AXE-B when directional patch antennas, wall-mount omni antennas, or another approved external antenna layout is required.
4. Align switch power with the expected radio state
Confirm an 802.3at source for 4×4 operation, 2.5G uplink speed, and USB availability; approve 802.3af only for reduced 2×2 and 1G operation.
Ordering Checklist
|
Order Gate |
What to Verify |
Procurement Risk |
|---|---|---|
|
Regulatory-domain match |
Use Cisco compliance resources to confirm that -B is valid for the installation country |
Ordering the wrong suffix can create a country-approval issue even when the AP family is correct |
|
AP family code |
Verify AXI internal-antenna hardware rather than AXE external-antenna hardware |
The antenna design is part of the PID and cannot be corrected with a software setting |
|
Power feed |
Budget 802.3at PoE or AIR-PWRINJ6= when full radio and uplink features are required |
802.3af or AIR-PWRINJ5= forces reduced radios, 1G Ethernet, and disabled USB |
|
Controller release |
Check the target Cisco controller platform and software release before rollout |
An unsupported controller path can prevent the AP from joining service |
|
Installation parts |
Confirm AIR-AP-BRACKET-1, AIR-AP-BRACKET-2, and ceiling clip choices against the mounting surface |
Missing mount hardware can delay installation after the AP arrives |
|
External antenna exception |
Change to C9115AXE-B when the RF plan needs approved RP-TNC external antennas |
C9115AXI-B is not the connector-based 9115AX model |
