Check the exact device
Menu names and behavior can vary by US hardware revision and firmware. This guide was researched from official material, not tested on a physical router.
Applies to: UniFi U7 Pro XG and U7 Pro XGS; different PoE classes despite similar model names.
Official evidence: UniFi U7 Pro XG official technical specifications, UniFi U7 Pro XGS official technical specifications.
Before you begin
- Identify the exact unit model, not just U7 Pro.
- Read the switch/adapter port PoE standard and remaining power budget before connecting.
Important: Never force an incompatible passive PoE adapter; active PoE class and power budgeting matter.
What to check / do
- Compare the vendor specs: U7 Pro XG uses PoE+ whereas U7 Pro XGS requires PoE++.
- Confirm that the powering switch or injector meets the correct class and has sufficient budget after other attached APs.
- Connect a 10GbE-capable cable/switch only when available; a 1GbE link may still function but limits wired throughput.
- Use UniFi Network to adopt and confirm the AP is online. For an adoption failure, check port VLAN and discovery routing before resetting the AP.
Verify the result
- The AP remains powered and stable through boot/adoption.
- The switch shows intended link rate and no PoE budget alarm.
If the result is not what you expected
- Stop changing settings if you cannot identify the model or a reliable administrator recovery path.
- Use the exact manufacturer support link below and quote your hardware label, firmware version, and what changed.
Restore / undo
Revert the switch port to its previous configuration and restore a compatible injector or upstream port if power alarms appear.
Evidence, limits and editorial disclosure
Technical claims are based on the linked manufacturer or ISP page as checked on 2026-11-01. This is an independent explanatory checklist, not a claim that RouterFix tested the device. Hardware revision, regional SKU and firmware menus may differ. Unverified functions must remain unknown.

If the XGS needs a separate PoE++ source
The U7 Pro XG and XGS have different input classes. Check the printed XGS model, its PoE++ requirement and the full 10GbE path before comparing adapter listings; do not substitute a passive injector.
