Ubiquiti POE-24-30W-G-WH PoE Adapter
Overview
The Ubiquiti POE-24-30W-G-WH is a 24V PoE adapter designed for UISP infrastructure deployments where localized power injection at the device level is required. This external power injector delivers 30W of power over a single Gigabit Ethernet port, making it suitable for powering compatible edge equipment, wireless access points, switches, and distributed network devices that operate on 24V PoE input. The model number POE-24-30W-G-WH identifies this as Ubiquiti's compact Gigabit variant in their PoE adapter family.
Unlike rack-mounted solutions, the external form factor allows flexible placement within network cabinets or direct field deployment without consuming valuable rack space. This is particularly useful in distributed or remote sites where cabinet real estate is limited or where the PoE injection point needs to be physically separated from the main switch.
Key Features
- 24V Power Output at 30W Capacity: Delivers 30 watts of 24V PoE power — sufficient for standard edge devices, access points, and managed switches operating within this power envelope. If your device draws more than 30W, you will need a higher-capacity model; if it draws less, this adapter will not overstress the unit.
- Gigabit Ethernet Port: Maintains full line-rate 1 Gbps connectivity while supplying power. This avoids a bottleneck for devices that require both adequate throughput and power injection, such as wireless access points serving multiple client streams or PoE-powered switches aggregating multiple access points.
- External Housing: Compact form factor designed for placement on shelves, DIN rails, or wall mounting within enclosures. Does not require rack space, reducing cabinet clutter and improving thermal airflow in confined installations.
- AC/DC Input: Powers from standard AC mains (110–240V) or DC sources where available, providing flexibility for deployment in locations where AC power availability may be intermittent or remote. Verify input voltage compatibility with your site's power infrastructure before purchase.
- UISP Ecosystem Integration: Purpose-built for Ubiquiti UISP (Unified Information Security Platform) infrastructure deployments. If integrating into a broader Ubiquiti UISP environment, this adapter aligns with existing management and provisioning workflows. For non-Ubiquiti devices, verify 24V PoE compatibility before deploying.
- Weight and Portability: Weighs 0.650 lb, making it easy to transport and install in field or cabinet settings without requiring additional mounting hardware or structural reinforcement.
Integration and Compatibility
The POE-24-30W-G-WH is designed for integration with Ubiquiti UISP devices and third-party equipment rated for 24V PoE input. Before deploying this adapter, confirm that your target device supports 24V PoE — many enterprise devices expect 48V PoE (802.3at/PoE+) or 95V PoE++ (802.3bt), and supplying 24V to a device expecting 48V will not provide sufficient power. Conversely, devices designed for 12V or lower will not accept 24V input.
The adapter integrates into existing Ubiquiti catalog installations where centralized PoE switching is unavailable or where remote device locations require localized power injection. If you are deploying multiple remote PoE devices across a site, consider planning your PoE switch infrastructure architecture to balance centralized injection (more cost-effective at scale) against distributed adapters (more flexible for heterogeneous deployments).
Deployment Context
This adapter is most cost-effective and operationally sound in scenarios where you have one or two devices requiring 24V PoE at a remote location without native PoE support. For large-scale deployments (10+ devices), a centralized PoE switch typically offers better TCO, easier management, and reduced cable clutter. However, for edge sites, temporary testing, or retrofitting power to legacy network infrastructure, the external POE-24-30W-G-WH adapter avoids the need to replace existing non-PoE switches.
Frequently Asked Questions
Q: Can the POE-24-30W-G-WH power a device rated for 48V PoE?
A: No. Devices expecting 48V PoE will not power on or operate correctly with 24V input. Verify your device's power input specification before deploying this adapter.
Q: What is the maximum cable run distance from the adapter to the powered device?
A: Standard Gigabit Ethernet (Cat5e or better) supports reliable power and data delivery over 100 meters (328 feet). Longer runs may experience voltage drop — consult Ubiquiti documentation or your cable manufacturer for runs exceeding 100m.
Q: Does the POE-24-30W-G-WH require any special configuration or driver installation?
A: No. This is a passive PoE injector. Plug the AC/DC input into power, connect your uplink to the Ethernet port, and connect the powered device to the PoE output. No software or firmware installation is required.
Q: Can I daisy-chain multiple POE-24-30W-G-WH adapters to power multiple devices?
A: No. Each adapter supports one downstream device at 24V, 30W. Daisy-chaining will not increase total power capacity; configure each adapter independently to each powered device.
Q: Is the POE-24-30W-G-WH suitable for outdoor or exposed-environment installations?
A: This adapter is designed for indoor cabinet or sheltered enclosure deployment. For outdoor use, you will need an outdoor-rated PoE injector or a weatherproof enclosure. Check environmental operating specifications in the product datasheet before deploying in cold, hot, or humid environments.

The POE-24-30W-G-WH is a straightforward tool for a specific job: injecting 24V power over a single Gigabit link where your edge device lacks native PoE support or where centralized PoE infrastructure cannot reach. This adapter solves the problem of retrofitting power to remote or legacy sites without replacing network switches, but it's not a substitute for proper PoE planning at scale.
Technical Highlights:
- 30W Power Budget at 24V: This is the hard ceiling — exceeding 30W will cause the adapter to thermal throttle or shut down. Know your downstream device's power draw before committing to this model. A wireless access point pulling 28W will work; one pulling 35W will not.
- Gigabit Line-Rate Connectivity: The adapter does not introduce a throughput bottleneck — data passes through at full 1 Gbps. Useful for access points or switches that aggregate multiple upstream links and need full bandwidth alongside power.
- AC/DC Dual Input: Flexibility to source power from either grid AC or local DC (common in remote cabinet installations with backup power systems). Verify your input voltage before powering on — wrong voltage input will damage the unit.
Deployment Considerations:
- Confirm 24V PoE compatibility on the downstream device — many enterprise devices default to 48V or 95V. Supplying the wrong voltage will not power the device and may cause damage.
- The external form factor means this adapter draws power from an outlet or UPS. If you're powering mission-critical infrastructure, plan for redundant power feeds or backup supply — a single adapter with a single power cord is a single point of failure for that site's connectivity.
Position the POE-24-30W-G-WH for remote site retrofits where you have one or two 24V devices and no existing PoE switch infrastructure. For multi-device rollouts, plan a centralized PoE switch instead — the per-port cost drops significantly and management scales.
