5USB 3.0 connector
(for connecting to the computer)

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.

Computer locks 10
Computer locks
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:
http://www.lenovo.com/support.

Replacing hardware
Before replacing hardware
Attention Do not open your computer or attempt any repairs before reading the Important
Product Information Guide.
Read these notes before replacing hardware:
• Some of the hardware components explained in this manual are optional.
• Use computer components provided only by Lenovo.
• When installing or replacing an option, use the appropriate instructions explained in this manual along
with the instructions that come with the option.
• In most areas of the world, Lenovo requires the return of defective CRUs (Customer Replaceable Units).
Information about this will come with the CRU or will come a few days after the CRU arrives.
Handling static-sensitive devices
Do not open the static-protective package containing the new component until the defective component
has been removed and you are ready to install the new component. Static electricity, although harmless to
you, can seriously damage computer components.
When you handle parts and other computer components, take these precautions to avoid static damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle parts and other computer components carefully. Handle PCI/PCI-Express cards, memory
modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the parts and other computer components.
• Touch the static-protective package containing the part to a metal expansion-slot cover or other
unpainted metal surface on the computer for at least two seconds. This reduces static electricity from
the package and your body before you install or replace a new part.
• When possible, remove the new part from the static-protective package, and install it directly in the
computer without setting the part down. When this is not possible, place the static-protective package
that the part came in on a smooth, level surface and place the part on the package.
• Do not place the part on the computer cover or other metal surface.

Knowing replaceable parts
Customer-Replaceable Units (CRUs)
CRUs are computer parts that a user can upgrade or replace. There are two types of CRUs: self-service and
optional-service.
Self-service CRUs You can install self-service CRUs easily. These CRUs might be standalone,
latched, or secured by up to two screws.
Examples of self-service CRUs include the keyboard, mouse, any USB
device, and the power cord. Other self-service CRUs might include memory
modules, adapter cards, hard disk drives, and optical drives.
Note Users are responsible for replacing all self-service CRUs.
Optional-service
CRUs
Handling optional-service CRUs requires some technical skills and simple
tools (such as a screwdriver).
These CRUs are isolated parts within the computer. They are usually
concealed by an access panel that is secured by more than two screws. You
must remove the screws and panel to access the specic CRU.
Optional-service CRUs can be removed and installed by users or, during the
warranty period, by a Lenovo service technician.
Field-Replaceable Units (FRUs)
FRUs are computer parts that a trained technician can upgrade or replace.
For detailed FRU information, such as the FRU part numbers and supported computer models, go to:
http://www.lenovo.com/serviceparts-lookup
