3: Installation of the SGX 5150 Power Table 3-6 Power Input Interface Power Input Description Barrel Connector  Center contact fork type for better grip  9-30 VDC Input with center = (+)  Reverse polarity protection up to 30 VDC USB Type C Connector  USB VBUS 5V powering (default setting)  SGX can provide VBUS 5V 0.5A out if configured as USB host, and powered by Lantronix provided wall adaptor, or PoE power source class 2 (hardware optional) Ethernet PoE RJ45 Connector  PoE power module is optional  Must provide class 2 PoE power source  Supports power inputs at both spare pins or Ethernet center taps with full bridge diodes for polarity in-discrimination. Power Consumptions  1.9 W typical if configured as USB Device, or USB Host - but not providing VBUS 5V power  5.5 W maximum if configured as USB Host and providing out VBUS 5V power  The internal hardware configuration allows more than one or all power sources applied at the same time to provide un-interrupted operation if one of them happens to fail (caution: may not be error-free). Not designed for one power source to take precedence over the other. Ethernet Ports The Ethernet port has two LEDs (see Table 3-2) that indicate the status of the connection as described inTable 3-8 and Table 3-9 below.
