Replaceable server components
The four types of replaceable components are:
v 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.
v 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.
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. One example of
an option-service CRU is the DASD backplane.
v Both types of CRUs are listed in the table on the following page.
v Field replaceable unit (FRU): FRUs must be installed only by trained service
technicians.
