Chapter 3. Customer Replaceable Units (CRUs)

Customer Replaceable Units (CRUs) are computer parts that can be upgraded

or replaced by the customer. There are two types of CRUs: Self-service CRUs

and Optional-service CRUs. Self-service CRUs are easy to install. They might

be standalone, latched, or require a screwdriver to remove a maximum of two

screws. However, Optional-service CRUs require some technical skills and in

some cases might also require simple tools, such as a screwdriver. However,

both Self-service and Optional-service CRUs are safe for the customer to

remove.

Customers are responsible for replacing all Self-service CRUs. Optional-service

CRUs can be removed and installed by customers or by a Lenovo service

technician during the warranty period. Lenovo servers contain both Self-service

and Optional-service CRUs.

v Self-service CRUs: These CRUs unplug or are secured by no more than two

screws. Examples of these types of CRUs include the keyboard, the mouse,

any USB device, and the power cord. Other Self-service CRUs depending on

product design might include memory modules, adapter cards, hard disk

drives, and optical drives.

v Optional-service CRUs: These CRUs are isolated parts within the server and

are concealed by an access panel that is typically secured by more than two

screws. Once the access panel is removed, the specific CRU is visible.

v Both types of CRUs are listed in the following table.

The Installation and User Guide provides instructions on how to replace

Self-service CRUs and Optional-service CRUs. Refer to the following table to

determine which publication contains the instructions you need. The

publications are available on the ThinkServer Documentation DVD and also the

Lenovo Web site at:
