PowerEdge 2950 error: RAC initialization failed.
Hi there, hoping someone's seen this before. I have a PowerEdge 2950 server. Multiple drives in a RAID 5 config. Drive 0 died (amber flashing light) after a nasty power outage. The HDs were all 75g SAS drives and were no longer available from Dell, so I used a Dell 300GB. The array rebuilt automatically, thankfully, and Windows booted up OK. I then did a BIOS update to 2.7, which completed OK and rebooted the system.
But then I got an error: Baseboard Management Controller Communication Failure. No loader.
Fortunately the server still booted to Windows, so I was able to download the latest Dell BMC Firmware 2.5, which got rid of that error. It also reset the error indicator on the front LCD to blue, so that was good.
Following that reboot, however, I have *another* new error and I'm trying to find the appropriate driver that (I hope) will solve this problem: Upon bootup, I get the following:
Remote Access Controller detected
!!*** Error: Remote Access Controller initialization failure ***
RAC virtual USB devices may not be available...
Is this another driver update, or is it possible that the BMC Firmware would have reset drac settings? I'll check the DRAC in a bit as Windows is back up and running and I'm trying to minimize downtime here.
Thanks for any help!

Sir_Tidbit,
First I wanted to say I am sorry about the delay in getting a response to your posting. The Community Forums had some maintenance to do and locked down shortly after your posting. I hope it hasn't caused too many issues for you.
In regards to the issue you are having. I would start by draining the flea power and then clearing the Nvram. To drain the flea power you will shut down the server and then pull the AC cord. After that hold down the power button for 20 seconds.
From there open the cover for the server and locate the NVRam jumper (shown below) and move the jumper over. After the jumper is moved then plug in the AC cable and power the server. ONCE you see indications of power (lights on the server) then power back down, then restore the jumper to it's original position. From there you need to leave the server sitting, powered down, but with the AC cable attached for about 2 minutes. After that power the server and see if the issue is resolved.
Let me know how it goes.
