We have a cluster of SC1435 without the DRAC card but they still have
the baseboard management. It should be accessible right at the end of
the POST by hitting ctrl+e and normally it shows a little splash
screen with the ip it has been configured with and what keys to press.
It gives some great information especially if you are running into
ram issues. I don't remember if we had to run on the logging or if it
was on from the factory.

We never tried to deal with lm_sensors on these machines because ipmi
had more options. We are using CentOS 5 on our cluster machines.
Here are a few links we used when working on ipmi.

The real key is to go back to the sales person that you purchased them
from and tell them the problems you are having and have them help
escalate the situation. I am not sure what diagnostics you are
running but they have a bootable cd for doing a memory test at the
link below. Even when they have tried to point at an OS problem if I
can get an error on that cd they really have nothing that they can
Best of luck,
