Replaceable server components

The four types of replaceable components are:
• Consumables: Purchase and replacement of consumables (components, such as batteries and printer
cartridges, that have depleting life) is your responsibility. If Lenovo acquires or installs a consumable
component at your request, you will be charged for the service.
• Self-service CRUs: these CRUs unplug or are secured by no more than two screws. Examples of
these types of CRUs include a USB device or the power cord. Other Self-service CRUs depending on
product design might include hot-swap hard disk drives, hot-swap fans, hot-swap power supplies,
memory DIMMs, and RAID cards.
• 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. One example of an option-service CRU is the DASD backplane.
• Both types of CRUs are listed in the table on the following page.
• Field replaceable unit (FRU): FRUs must be installed only by trained service technicians.
The following illustration shows the major components in the server. The illustrations in this document
might differ slightly from your hardware.
