Chapter 7. FRU replacement notices

This chapter presents notices related to removing and replacing parts. Read this chapter carefully before
replacing any FRU.
CRU statement for customers:
You can resolve some problems with your product with a replacement part you can install yourself, called a
"Customer Replaceable Unit" or "CRU." Some CRUs are designated as self-service CRUs and others are
designated as optional-service CRUs. Installation of self-service CRUs is your responsibility. For optional-
service CRUs, you can either install the CRU yourself or you can request that a Service Provider install the
CRU according to the warranty service for your product. If you intend on installing the CRU, Lenovo will ship
the CRU to you. CRU information and replacement instructions are shipped with your product and are
available from Lenovo at any time upon request. You can find a list of CRUs for your product in this Hardware
Maintenance Manual. An electronic version of this manual can be found at
Documentation and then follow the on-screen instructions to find the manual for your product. You might be
required to return the defective CRU. When return is required: (1) return instructions, a prepaid shipping label,
and a container will be included with the replacement CRU; and (2) you might be charged for the
replacement CRU if Lenovo does not receive the defective CRU within thirty (30) days of your receipt of the
replacement CRU. See your Lenovo Limited Warranty documentation for full details.
This chapter presents notices related to removing and replacing parts. Read this chapter carefully before
replacing any FRU.
