See Chapter 3, “Parts listing, System x3755 Type 8877 and 7163,” on page 25 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).
v
If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
