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 In-Wall, and model-specific PoE output constraints on U6 Enterprise In-Wall.

Official evidence: UniFi U7 In-Wall official technical specifications, UniFi U6 Enterprise In-Wall official technical specifications.

Before you begin

  • Check AP input port, LAN output port markings, and specific powered client wattage.
  • Verify that the upstream switch reports a sufficient IEEE PoE class and has spare budget.

What to check / do

  1. Distinguish the AP's 2.5GbE uplink from its downstream LAN ports; Ethernet port speed does not imply power delivery.
  2. Consult the exact AP spec for which input power tier enables downstream PoE (U7 In-Wall vs U6 Enterprise In-Wall differ).
  3. Disconnect downstream powered clients, verify AP boots alone, then add the client after confirming allowable output port and available watts.
  4. If the client fails, compare switch power draw and AP power budget before changing any VLAN or DHCP setting.

Verify the result

  • AP stays adopted and stable when the client is attached.
  • Downstream client shows negotiated data link and a valid power state within vendor limits.

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

Unplug only the downstream powered client and restore the original upstream PoE port/adapter class if the shared budget is exceeded.

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.
