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 3.0 connectors on the I/O box each provides 500 mA and 900mA
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 port 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 3 and 4 on the rear of the computer.
• The I/O box enables you to wake up the computer from S3 standby mode through operations on devices
connected to the I/O box connectors.
