Cisco Phihong POE80U-560 80W Gigabit PoE Injector – 56V Four-Pair Midspan
A single-port 80W power over Ethernet injector that delivers 56V DC across all four pairs alongside gigabit data, for high-power network devices. Rated from -40 to +55°C and backed by a 12-month warranty from Reboot IT.
Key Benefits
- 80W output – 56V DC at up to 1.43A for high-draw powered devices.
- Four-pair power – delivers power across all four pairs of the network cable.
- Gigabit data – passes 10/100/1000Mbps data alongside power.
- Wide AC input – accepts 100–240V AC, 50/60Hz mains.
- Wide temperature range – rated to operate from -40 to +55°C.
- Cisco outdoor AP specification – its 80W 56V four-pair rating matches the injector Cisco specifies for Aironet 1550 series outdoor access points.
Performance in Use
A midspan injector sits between a standard network switch and a powered device. Plug the data cable from your switch into the injector, run a single cable from the injector to the device, and the device receives both network data and power — useful where there is no suitable PoE switch, or where a device needs more power than a normal PoE port provides.
The POE80U-560 is built for high-draw equipment. It supplies 56V DC at up to 1.43A over all four pairs of the cable, for a total of 80W, while still passing gigabit data. That rating matches the power injector Cisco specifies for its Aironet 1550 series outdoor wireless access points.
Its -40 to +55°C operating range suits comms rooms, plant rooms and cabinets that are not climate controlled. Before connecting, confirm your device is designed for 56V four-pair power: this is not a standard 802.3at or 802.3bt injector.

Is It Right For You?
| Best For ✓ | Not For ✗ |
|---|---|
| Cisco Aironet 1550 series outdoor access points | Standard 802.3af/at devices without checking compatibility |
| High-power devices designed for 56V four-pair power | Devices that need 802.3bt or Cisco UPOE negotiation |
| Sites without a suitable high-power PoE switch | Multi-port power – this injects power on one port |
| Replacing a failed 80W injector | Low-power phones where a standard PoE switch will do |

Frequently Asked Questions
Is this an 802.3at or 802.3bt injector?
No. It delivers 56V over four pairs using Phihong Ultra PoE with 802.3af detection. It is not an 802.3at, 802.3bt or Cisco UPOE device, so check your equipment is designed for this type of power.
What devices is it used with?
Its 80W 56V four-pair rating matches the injector Cisco specifies for Aironet 1550 series outdoor access points. Always confirm your device’s power requirement before connecting.
Does it slow down my network?
No. It passes 10/100/1000Mbps data, so gigabit links stay at gigabit speed.
How many devices can it power?
One. It is a single-port injector with one data input and one data-plus-power output.
Can it be used in a hot or cold location?
It is rated to operate from -40 to +55°C.
How much does shipping cost?
Standard shipping is free Australia-wide. Faster options are available at checkout.
