Power Supply - Allied Telesis x330-10GTX Installation Manual

Power Supply

The switch has one internal power supply. The power supply is not field-
replaceable. Refer to "Power Specifications" on page 93 for the input
voltage ranges.
The switch supports IEEE 802.3az Energy-Efficient Ethernet (EEE). EEE
is an energy saving feature that reduces power consumption during
periods of no data activity. The switch saves electricity by placing the
Ethernet circuitry in a special sleep mode when all the ports are inactive.
When data activity resumes, the circuitry automatically resumes normal
operations.
Warning
Power cord is used as a disconnection device. To de-energize
equipment, disconnect the power cord.  E3
