the AC LED.
The power supplies are auto-sensing and auto-switching, and provide up to 300
watts of total output power, having a universal input (90 VAC to 264 VAC) and 12
VDC regulated output.
Power supplies can be swapped in or out of the device while the device is running,
and without opening the device. You can remove one of the supplies without
interrupting operation because the remaining power supply provides enough power
for all of the ports.
For power supply hardware specifications, refer to “Power supply specifications” on
page 48.
