Chapter 10. FRU lists
Notes:
1. In the following tables, A CRU (Customer Replaceable Unit) is identified by
either a 1, 2, or N in the CRU Tier column. A ″1″ means that the part is a Tier 1
CRU, A ″2″ means that the part is a Tier 2 CRU, and an ″N″ means that the
part is not a CRU.
2. For some machine types, there is a column with a heading of RoHS?. This
column contains a “Y“ if the FRU is RoHS compliant or an “N“ if the FRU is
not RoHS compliant. Please read “Important information about replacing RoHS
compliant FRUs” on page 2 before replacing any FRUs.
