I/O box 9
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 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.

Attaching a Kensington-style cable lock
You can use a Kensington-style cable lock to secure your computer to a desk, table, or other
nonpermanent xture. The cable lock connects to the security-lock slot at the rear of your computer.
Depending on the type selected, the cable lock can be operated with a key or combination. The cable lock
also locks the buttons used to open the computer cover. This is the same type of lock used with many
notebook computers. You can order such a cable lock directly from Lenovo by searching for Kensington at:
