Re: Install Fails on T5240

Also,

According to this doc:

https://docs.oracle.com/cd/E19712-01/820-3318-14/820-3318-14.pdf

These systems require 1.5v FB DIMMS

FB-DIMM Configuration Guidelines for Sun SPARC Enterprise T5240 Servers
When planning FB-DIMM upgrades to Sun SPARC Enterprise T5240 servers,
observe the following memory configuration guidelines:
 ■ The motherboard has 16 slots that support industry-standard FB-DIMMs.
 ■ Use only 1.5-volt FB-DIMMs in SPARC Enterprise T5140 and T5240 servers.
 ■ Sun SPARC Enterprise T5240 servers support three FB-DIMM configurations:
 ■ 8FB-DIMMs (Group 1 in FIGURE: FB-DIMM Configuration on Motherboard
 (Sun SPARC Enterprise T5240 Servers) on page 101)
 ■ 12 FB-DIMMs (Groups 1 and 2 in FIGURE: FB-DIMM Configuration on
Motherboard
 (Sun SPARC Enterprise T5240 Servers) on page 101)
 ■ 16 FB-DIMMs (Groups 1, 2, and 3 in FIGURE: FB-DIMM Configuration on
 Motherboard (Sun SPARC Enterprise T5240 Servers) on page 101) ■
 SPARC Enterprise T5240 servers can be equipped with a memory mezzanine
 assembly, which provides an additional 16 FB-DIMM slots.
 ■ All FB-DIMMs within a single CMP branch must have the same capacity.
 ■ If the System Firmware is at least version 7.1.7.f,
 the FB-DIMM capacities on different CPUs can be different.
 ■ When replacing a faulty FB-DIMM, the replacement FB-DIMM must have the
 same FRU part number as the FB-DIMM being replaced.
 If you are not able to obtain a replacement FB-DIMM with the same FRU part
 number, may need to replace all the FB-DIMMs in the branch to ensure that
 all FB-DIMMs in that branch have the same FRU part number.
