Important information about replacing RoHS compliant FRUs
RoHS, The Restriction of Hazardous Substances in Electrical and
Electronic Equipment Directive (2002/95/EC) is a European Union legal
requirement affecting the global electronics industry. RoHS requirements
must be implemented on Lenovo products placed on the market after
June 2006. Products on the market before June 2006 are not required to
have RoHS compliant parts. If the original FRU parts are non-compliant,
replacement parts can also be non-compliant. In all cases if the original
FRU parts are RoHS compliant, the replacement part must also be RoHS
compliant.

Single failures can occur for a variety of reasons that have nothing to do with a
hardware defect, such as cosmic radiation, electrostatic discharge, or software
errors. Consider replacing an FRU only when a problem recurs. If you suspect that
an FRU is defective, clear the error logs and run the test again. If the error does
not recur, do not replace the FRU.
