* Active airflow and adequate cooling required for stable continuous operation at high load.

Install PoE HAT onto the 40-pin GPIO header. Attach black wire from fan to GND pin on PoE HAT. Attach red wire from fan to 5V (performance) or 3.3V (quiet) pin on PoE HAT. Insert MicroSD card with properly flashed OS. Attach Ethernet cable from a 802.3af PoE switch.
ULTIMATE POWER OVER ETHERNET HAT FOR RASPBERRY PI 4: Deliver clean and reliable power to the latest Pi 4! Power-over-Ethernet is both simple, power efficient, and cost effective compared to having multiple power adapters. PoE power output must be within the budget of the switch when powering multiple boards. PoE switch and Raspberry Pi 4 Model B sold separately.
STANDARDS COMPLIANT POWER OVER ETHERNET SWITCH REQUIRED: The network switch or power sourcing equipment (PSE) must be compliant with the IEEE 802.3af or 802.3at PoE standard, particularly section 33.4.1 with regards to PSE electrical isolation of the leads. "Passive PoE" (DC 24V or 48V) is not standards compliant and may cause damage to equipment. Some Ubiquiti switches do not provide provide proper isolation so please use the professional version!
BUILT FOR CLUSTER NODES: Simplify cable management and expand your on-premise cloud with POE! Power five, ten, twenty Raspberry Pi 4 Model B boards through a single POE switch. This PoE HAT was designed to exceed the power delivery standards set by the official Raspberry Pi PoE HAT and other products available on the market.
VENTILATED CASE WITH COOLING FAN HIGHLY RECOMMENDED: Do not use this product in an enclosed case without active air circulation. Airflow around the HAT and Raspberry Pi 4 Model B must be adequate to ensure performance and stable operation.
EASY INSTALLATION AND BACKWARDS COMPATIBLE: Please remove all non-essential heatsinks including RAM/USB/Ethernet heatsink before seating the HAT! Supports the latest Raspberry Pi 4 as well as the Raspberry Pi 3 Model B+.
