When the player is powered via Type 1 PoE, the total available power is reduced to 12W. This leads to several performance restrictions:
Only one CPU core is operational: Processor-intensive applications have slightly reduced performance.
Each USB port supplies 100mA of power (one unit load for USB 2.0): This is sufficient for low-power devices such as memory sticks and mice. High-power devices such as hard disks will not operate.
A player installed with an internal SSD drive should not use HDMI Input: Both peripherals consume significant power.
