AirWave will support the firmware version running on the AP375. So depending on if the AP375 is a AOS or IAP you will need to check the Supported Devices documentation to confirm that the AirWave version you are running supports that OS version. The minimum firmware version for an AP375 is ArubaOS & Aruba InstantOS 8.3.0.0.
AirWave 8.2.6.1 and beyond appears to support AOS 8.3.0.0 and Instant 8.3.0.0.
You can find this information and further information on the support site.
