    After a power-outage, there's RED Lamp inside My mac pro.

    I do a Diagnosis (by inserting the DVD Installer that came with My Mac Pro, and pressing "D" at the startup chime)

    And I got this problem/trouble:
    Code:
    4SNS/1/40000001:VMBS
    Anyone know what problem is that??

    But Thanks God when I totally unplug My Mac Pro few mins, and then plug it back, all RED Lamp inside My Mac Pro were gone!!

    And when I do a Diagnosis again, there is no problem/trouble found.

    Has anyone encountered the same problem with mine??

    Any reply would greatly appreciated.

    Thank you.

    I had a power cut a few months ago.

    When the Mac Pro came back on, all the red warning LED's were lit. Both on the motherboard and RAM riser boards. Although I only noticed this after several hours of use.

    I just restarted and everything seemed ok. Nothing else has happened since.

    Yeah, That's what I found on My Mac Pro when I had a power-cut on My Mac Pro.

    Is it normal?

    Have you tried to run Apple's Diagnostic Tool when the RED Leds on?

    Thank you.

    No I didn't try to run the Apple's Diagnostic Tool at the time, and I haven't had it happen again.

    I have run Apple's Diagnostic Tool though a few weeks later and it didn't find any problems. (I had a load of Kernel panics, which was solved by reinstalling OS X. I'm pretty sure the two are unrelated though)

    Mine is normal too, all red lights inside My Mac Pro were gone after I unplugged My mac Pro and then plug the power cord back in.

    And when I did Apple Diagnostic Tool, there is no problem/trouble found.

    Anyone else encountering the same problem with ours ??

    And what that error code refers to, anyone know ??

    The AHT error code is:

    Code:
    4SNS/1/40000001:VMBS

    I get this red light when I remove the plastic sheet on my G5 while the comp is running. I also had it happen when I upgraded my graphics card and didn't connect power to the card

    4 from Memory Card Riser A
    4 from Memory Card Riser B
    2 from Main Board
