Sun Fire X4600 to Sun Fire X4600 M2
Server Migration
This manual describes procedures for upgrading a Sun Fire X4600 server to a Sun
Fire X4600 M2 server.
These two systems share a chassis and motherboard. They differ in firmware, which
determines the CPU modules and DIMMS that they support:
The Sun Fire X4600 server supports CPU modules that use AMD Opteron 800
■
series CPUs and DDR1 DIMMs.
The Sun Fire X4600 M2 server supports CPU modules that use AMD Opteron
■
8000 series CPUs and DDR2 DIMMs.
No one set of system firmware supports both kinds of CPU modules. Two firmware
update streams are maintained. Because the two firmware update streams support
different hardware, the upgrade procedure is more complicated than for a typical
firmware upgrade.
Note – If you plan to upgrade a Sun Fire X4600 system to use CPU modules with 4
or more cores, you must upgrade the system to be a Sun Fire X4600 M2, as described
in this manual.
Upgrade Procedure
The upgrade procedure has four stages:

"Populating a Server With CPU Modules" on page 3
