Sun Ultra 40 M2 clicking sound in PSU

Sun Ultra 40 M2 clicking sound in PSU

Need help, I unplugged a RAM module in my Sun Ultra 40 machine and when I tried to power it on it fails.

There is a clicking sound when the power cord is plugged to the PSU.  Then there is a small blinking dot like yellow light in the motherboard and the label on the light says "PWR CR11".  System would no longer power on apart from the clicking sound and blinking.

Is this a problem with the motherboard or PSU or is there something I can reset in the hardware to fix this problem?

Thanks a lot in advance for any help.

RE: Sun Ultra 40 M2 clicking sound in PSU

Do you get any beeps on startup? Usually a badly hurt system will try to communicate with beeps and lights.

Have you checked the support manuals for the Ultra 40? They should give troubleshooting tips that are specific to the 40. That should include beeps, keyboard flashes, and motherboard lights. Oracle should have that online.
