Lightbulb Powering ON SUN 450 Enterprise
Problem powering ON the SUN 450 E, we checked voltage and the power supply. Seems to be we have out of 3 LED's in the back 2 are glowing, when we turn the power button on the front from standby to ON.

Does anyone know how to troubleshoot this?.

I have looked through some troubleshooting documentation from SUN, tried removing all PCI slots and DMM's while starting.

Any help is appreciated!

Thanks

It's not likely your issue, but E450's did have an annoying "feature" that if the case wasn't secured properly the box wouldn't power on. Occasionally after opening one up for hardware work I'd fail to get the cover on the side seated perfectly before screwing it in and the box wouldn't power up till I fixed that.

One of them turned back on fine, when we cover the it properly. The other looks a bit problematic still. Thanks for the response.
