Frequently Asked Questions

Ubiquiti UniFi Switch Ultra 8-Port Gigabit PoE+ Managed Network Switch (USW-ULTRA)
Frequently Asked Questions (FAQ's)



What does the “Ultra” designation mean for this switch?
  • The “Ultra” line reflects higher‑end capabilities within the UniFi switch portfolio—such as higher PoE budgets, compact mounting options, and full feature set at Layer 2. It’s targeted at deployments needing both performance and flexibility.
    • How many PoE ports and what type of PoE are supported?
  • The switch provides seven Gigabit RJ‑45 ports that support PoE+ (802.3at) output, up to 30 W per port. One additional RJ‑45 port is designated for PoE++ input (802.3bt or higher) or AC power input.
    • What is the total PoE power budget?
  • That depends on how you power the switch. With an AC adapter rated at 210 W, total PoE budget can reach ~202 W. With PoE++ input only, budget is significantly lower.
    • Does it support managed switch features?
  • Yes. Though it is a compact desktop/edge switch, it supports Layer 2 management features such as STP/RSTP, port mirroring, storm control, egress rate limiting, jumbo frames and more.
    • Is this switch suitable for home use?
  • Absolutely—but its feature set and PoE budget may be overkill if you only need a simple switch. If you are powering multiple cameras, access points or VoIP phones and want centralized management, then it’s a great fit.
    • What mounting options are available?
  • It supports desktop placement, wall mounting, and magnetically mounting (depending on variant and installation environment).
    • What is the footprint and weight?
  • Approximate dimensions: 203 × 76 × 33 mm (8″ × 3″ × 1.3″) and weight around 320 g (11.3 oz) for the main unit.
    • Can it be powered via PoE rather than AC?
  • Yes—it supports PoE++ input on one port as an alternative to AC power. This allows flexibility in installation where AC might not be conveniently available.
    • How “quiet” is it?
  • The unit is fan‑less, which means it operates silently—making it ideal for office environments or places where noise is a concern.
    • Does it support VLANs and traffic segmentation?
  • Yes. The switch supports up to 256 VLANs and full Layer 2 segmentation features.
    • What kind of devices can I power with it?
  • Any device compatible with PoE/PoE+ standard—such as UniFi access points (WiFi 6/6E), IP cameras, VoIP phones, IoT sensors. With the high PoE budget, even multiple such devices can be powered reliably.
    • Is this a managed switch or unmanaged?
  • This is a managed switch (Layer 2) with full integration into the UniFi management platform—meaning you can monitor ports, traffic, PoE usage and configure features centrally.
    • What happens if I connect high‑wattage devices exceeding the budget?
  • The switch will allocate power as configured and may disable PoE on lower‑priority ports or throttle usage if the total budget is exceeded. It’s best practice to plan your PoE budget with margin.
    • Can it be used in rack‑mount environments?
  • Yes for small racks or network enclosures, though it does not include standard rack ears by default—it’s more focused on wall or desktop mounting rather than 19‑inch full rack.
    • Does it support future network speed upgrades (10G)?
  • This model is an 8‑port Gigabit switch; while excellent for PoE and gigabit devices, if you expect many 10Gb links you’d plan for a higher-tier model.
    • Can I monitor individual port power usage?
  • Yes—via the UniFi management interface you can view PoE usage per port, device status, link speeds and more within the UniFi ecosystem.
    • Is firmware updating supported?
  • Yes—firmware upgrades for features and security fixes are supported through the UniFi controller.
    • Are there comparable models I should consider?
  • Yes. If you have fewer PoE output needs or lower budget, the UniFi Switch Lite 8‑PoE may be suitable. But the Ultra offers more power‑budget and flexibility. Some users report that the Lite offers more advanced Layer 2 features; check your requirements carefully.
    • Can this switch operate in environments without a UniFi controller?
  • While the USW-ULTRA is designed to be managed via the UniFi Network Controller for full feature access and monitoring, it can technically pass traffic without a controller once configured. However, without the controller, you won't be able to adjust settings, monitor traffic, or perform firmware updates—making it strongly recommended to use it within a UniFi-managed environment for best results.
    • What should I check before deployment?
    • Ensure your power input (AC adapter or PoE++ source) can support the full PoE budget you plan.
    • Plan your cable runs and devices to ensure each port’s wattage suits connected devices.
    • Use the UniFi controller for initial configuration and monitoring.
    • Mount in a location with adequate ventilation (it’s fanless but still needs ambient airflow).
    • Verify that your environment’s temperature range is appropriate (this unit supports wide ambient ranges).
