NOTE:
The micro USB 2.0 compliant port can only be used as an iDRAC Direct or a management port.
NOTE:
The USB 2.0 specifications provide a 5 V supply on a single wire to power connected USB devices. A unit load is
defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a
port in USB 2.0; 6 (900 mA) in USB 3.0.
NOTE:
The USB 2.0 interface can provide power to low-power peripherals but must adhere to USB specification. An
external power source is required for higher-power peripherals to function, such as external CD/DVD Drives.
