Chapter 4 Replacing Motherboard Assembly Components 4-23
Note – FB-DIMM names in ILOM messages are displayed with the full FRU name,
such as /SYS/MB/CMP0/BR0/CH0/D0.
4.6 Replacing FB-DIMMs
This section describes how to diagnose and replace faulty FB-DIMMs. For FB-DIMM
configuration guidelines, see Section 4.5, “FB-DIMM Layout” on page 4-19.
Caution – Ensure that all power is removed from the server before removing or
installing FB-DIMMs. You must disconnect the power cables before performing this
