Dell Precision T7600 Workstation Diagnostic Amber LED Question

We have a Dell Percision T7600 server that was working fine until recently.  We powered it off and powered it back on and it now has a number 3 and number 4 lights on in AMBER (not green) and will not boot?

We have searched the Internet and the manual of the machine and found information about the diagnostic codes in green but not orange.

Nothing has changed on this system and was running fine so we are trying to figure out what 3 and 4 in orange mean so we can fix it?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Memory modules are detected, but a memory power failure has occurred.
• If two or more memory modules are installed, remove the modules, then reinstall one module and re-start the computer. If the computer starts  normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error. If only one memory module is installed, try moving it to a different DIMM connector and re-start the computer. • If available, install verified working memory of the same type into your computer.
