The XT245, XT1145, and XT2145 are designed for sustained ambient temperatures between -10°C and 50°C, with transients up to 60°C to 70°C (at 90% maximum relative humidity, non-condensing). Operating the players above 50°C ambient for prolonged periods may reduce the operational life of the product and result in intermittent resetting of the device.

When the player is powered via Type 1 PoE, the total available power is reduced to 12W. This leads to several performance restrictions:
...
means that 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
