I have had that line from a few companies.
Looks like you are talking to first or second line support people - this is
what they have been trained to say.
You can understand this - it stops idiots calling in to them who are trying
to run some spit-and-sawdust distribution they got free with a packet of
breakfast serial.
Again, just use your salesman or account manager and say that you spent $$$
with Dell to run applications,
and that the systems were sold to you as being able to run Linux.

The light coming on indicates a fault.
You should be interrogating the onboard management controller (called an
IPMI card ort a BMC, or in Dell speak I think a DRAC).
Log onto the suspect nodes anr run ipmitool:

ipmitool -I open sel elist

Do you not get a fault code on the little screen beside the light?
