Hello friend.
folow the next Step-by-Step Configuration
Verify the Affected AP's System Profile: First, you need to identify which system profile the AP in question is using. You can check this in the AP database or in the AP's configuration on the controller.
Create a New AP System Profile (If Necessary):
If the AP you want to modify is using a system profile that is also used by other APs you don't want to have IPM enabled on, then you must create a new "AP system profile."
If the affected AP is using a unique system profile that isn't shared by any other AP, then you can directly modify that existing profile.
Configure IPM in the System Profile:
Navigate to Configuration > System > Profiles tab in your controller or Mobility Master.
In the "All Profiles" list, expand the AP menu and then select AP system.
Select the profile you identified or created for the specific AP.
Expand the IPM section.
Select the IPM Activation checkbox to enable IPM.
(Optional but recommended) You can configure the "IPM Power Reduction Steps With Priorities" if you want to define specific power reduction behavior. This allows the AP to gradually disable certain functions (like USB ports, radios, etc.) to stay within the power budget. Without defining steps, the AP might operate without the 'r' flag, but it's good to have control over what IPM disables if power consumption exceeds the budget.
Click Apply or Save Settings.
Assign the New System Profile to the AP (If You Created One):
If you created a new "AP system profile" in Step 2, you now need to assign it to the specific AP. This is done in the individual AP's configuration or within the "AP Group" the AP belongs to, ensuring that only this AP uses the modified profile.
If the AP was already using a unique profile, this step is not necessary.
Important Considerations
PoE-AF Impact: The fact that your AP reboots into a restricted mode (rI flag) with PoE-AF indicates that the power source (802.3af) isn't providing enough power for the AP's full operation. 802.3af provides up to 15.4W, while many newer Aruba APs require PoE+ (802.3at, 30W) or even PoE++ (802.3bt, 60W) to operate without restrictions and with all features enabled (like radios, USB ports, etc.).
IPM Function: IPM allows the AP to dynamically adapt to the available power budget. If the AP is powered by PoE-AF and IPM is enabled, the AP will try to operate unrestricted initially but will dynamically apply restrictions (disabling certain functions) if power consumption exceeds the PoE-AF budget. This could clear the rI flag as the AP actively manages its consumption, but it's crucial to understand that some functionalities might be limited.
Check AP Datasheet: It's always advisable to consult the specific datasheet for your Aruba AP model to determine the exact power requirements and how the AP behaves with different PoE standards.
