compliant.
Note: RoHS and non-RoHS FRU part numbers with the same fit and function are identified with unique
FRU part numbers.
Lenovo plans to transition to RoHS compliance well before the implementation date and expects its suppliers
to be ready to support Lenovo's requirements and schedule in the EU. Products sold in 2005, will contain
some RoHS compliant FRUs. The following statement pertains to these products and any product Lenovo
produces containing RoHS compliant parts.
RoHS compliant ThinkCentre parts have unique FRU part numbers. Before or after June, 2006, failed RoHS
compliant parts must always be replaced using RoHS compliant FRUs, so only the FRUs identified as
compliant in the system HMM or direct substitutions for those FRUs can be used.
Products marketed before June 2006 Products marketed after June 2006
