Allied Telesis does not sell power supplies for these products. Power
supplies can be purchased from power supply manufacturers.
Here are the power supply requirements for the AT-IE300-12GT Switch:
DC voltage between 12 and 55VDC.

DC voltage must not exceed 55VDC.

The DC power supply must be capable of supplying 30 watts

continuously over the operating temperature range of -40° C to 75°
C (-40° F to 167° F).
The AT-IE300-12GT Switch can be powered by one or two power
supplies. A single power supply that meets the above requirements can
fully power the switch. Adding a second power supply adds power
redundancy.
Here are the power supply requirements for the AT-IE300-12GP Switch:
DC voltage between 46 and 55VDC. A DC voltage of 53.5V

provides the maximum power budget of 240W for powered
devices.
DC voltage must not exceed 55VDC.

The DC power supply must be capable of supplying 320 watts

continuously over the operating temperature range of -40° C to 75°
C (-40° F to 167° F).
Like the AT-IE300-12GT Switch, the AT-IE300-12GP Switch can be
powered by one or two power supplies. A single power supply that meets
the above requirements can fully power the switch and provide the
maximum 240W of power for powered devices. Adding a second power
supply adds system and PoE power redundancy.
Note
A 48VDC power supply for the AT-IE300-12GP Switch must have an
absolute maximum tolerance of +2.5% when adjusted to 53.5VDC at
the input to the switch, to provide full Hi-PoE power.
