<dt>Issue</dt>
<dd>Connected device to {{{name}}} is not powered via PoE</dd>
<dt>Solution I</dt>
<dd>Check if connected device supports 802.3af and/or 802.3at PoE standard(s)</dd>
<dt>Solution II</dt>
<dd>Check if {{{name}}} is powered with PSU, which outputs 44 VDC or higher voltages and can provide at least 2 W + connected device needed power</dd>
<!--- <dt>Solution III</dt>
<dd>If using 10/100 Mbps connection, make sure that your cable has connected all wiring pairs</dd> --->

<dt>Issue</dt>
<dd>All PoE devices and switch lost power after connecting more than two device to {{{name}}}</dd>
<dt>Solution</dt>
<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 all connected devices to PoE ports combined required more that 60 W of power, PSU was overloaded and turned itself off.<br>If full 120 W power budget is necessary, {{{name}}} must be powered with PSU, which can provide at least 130 W power at 44 VDC or higher voltages</dd>
