______________________ Note _______________________
When you upgrade from dual, redundant MC1 hardware to
dual, redundant MC2 hardware, you must replace all the MC1
hardware on one interconnect before you start on the second
interconnect (except as described in step 4 of Table 5–4).
Memory Channel adapters jumpered for 512 MB may require a
minimum of 512 MB physical RAM memory. Ensure that your
system has enough physical memory to support the upgrade. For
two MC2 Memory Channel adapters, you will need more than 1
GB of physical memory.

Dual, Redundant MC1 Interconnect to MC2 Interconnects

After the system is at the console prompt, use the console set command
to set the auto_action console environment variable to halt. This
halts the system at the console prompt when the system is turned on,
ensuring that you are able to run the Memory Channel diagnostics.
