Power Output

The CSS106-1G-4P-1S model can supply PoE powering to external devices from its Ethernet ports. This is convenient, as you don't need any additional PoE injectors to power other devices. The output voltage will be the same as the input Voltage. By default, it is set to "auto", so it is safe to plug any device into the powered ports. The maximum power output of each ethernet port in this mode is 1 A, total for all ports 2 A. Once Power Output is enabled in RouterOS, the Ethernet LED light turns from Green to Red. Red LED means the port is currently providing PoE power. For the best PoE output functionality, please use the power jack to power the CSS unit.
