Using the I/O box

When you use the I/O box with the ThinkCentre tiny computer, note the following:

  • The I/O box supports a maximum current rating of 5 A. It is recommended that you connect low-current devices to the I/O box and connect high-current devices directly to the ThinkCentre tiny computer to ensure the best performance of the devices.
  • The USB 2.0 connectors and USB 3.1 Gen 1 connectors on the I/O box provide a current of 500 mA and 900 mA current, respectively. When you connect a high-current storage drive to only one USB connector, the system might not recognize the device. You can connect the storage drive to two USB connectors on the I/O box.
  • The serial connector does not support hot swapping. Do not connect a device to the connector or remove a device from the connector while the system is running.
  • The connectors on the I/O box cannot be enabled or disabled individually. To enable or disable any of the connectors on the I/O box, enable or disable the USB connectors on the rear of the computer.
  • The I/O box enables you to wake up the computer from standby mode through operations on devices connected to the I/O box connectors.
