Network Devices
The power supply supports a variety of products from Allied Telesis,
including the IE200, IE300, and IE340 Series of Industrial Ethernet
Switches. For a complete list, refer to the Allied Telesis web site.
The power supply has a maximum DC output power of 480W. The output
power can be less, depending on AC input voltage and ambient
temperature. Refer to the “Derating Graph - Operating Properties and
Ambient Temperature” on page 70.
The product can support multiple powered devices simultaneously, up to
its maximum DC output power. Your installation plans should include
determining the power requirements of the individual devices before
connecting them to the power supply. You need to ensure that their total
power requirements do not exceed the available power of the product.
Note
The power supply does not alert you if the powered devices exceed
its maximum output power.
Power devices can be wired directly to the DC Output connectors on the
power supply. This is the preferred method when connecting one or two
devices. Connecting more than two devices requires a power distribution
system, such as DC bus bars. This guide does not explain how to install
power distribution systems. Consult with a qualified electrician.
