Note:
The S3928P-PWR-EI/S3952P-PWR-EI provides overtemperature protection
mechanism which enables the switch to shut down the PoE function on all the ports
when the internal temperature is over 65°C (149°F). The switch restores the PoE
function on all the ports when the temperature falls below 60°C (140°F).
The S3928P-PWR-EI/S3952P-PWR-EI can only use PoE external power supply
recommended by Huawei-3Com as the DC-input, otherwise, the device can be
damaged.
