<dd>{{{name}}} supports 802.3at standard, were each port can supply up to 30 W of power at PSE with total power budget of 120 W per all 4 ports. Standard PSU, which comes in the box with {{{name}}}, provides ~65 W power and limits power budget to ~60 W. If connected to PoE all connected devices to PoE ports combined required more that 60 W of power, PSU was overloaded and turned itself off. If full 120 W power budget is necessary, {{{name}}} switch must be powered with PSU which can provide 130 W po at 44 VDC or higher voltages</dd>
