Sonos app shows a “limited output” message for Era 100 Pro

Era 100 Pro is compatible with PoE (802.3af), but it is optimized for PoE+ (802.3at). The Sonos app will show a “limited output” message when your Era 100 Pro is connected using PoE instead of PoE+.

Era 100 Pro’s maximum performance differs depending on the PoE standard being used. When connected using PoE instead of PoE+, Era 100 Pro’s volume and bass output may be reduced at higher volume levels.

We recommend pairing Era 100 Pro with a PoE+ switch or Power Injector for maximum performance.

You can find more information on PoE standards, PoE equipment, and power budgeting in our Era 100 Pro User Guide.
