View Full Version : Powering up a Sun E-450

May 29th, 2012, 06:20 PM
Hi all,

I managed to get a replacement keyswitch for the Sun E-450, in fact got an entire media bay, swapped everything out and i still can not get the unit to power on no matter what position the key is in.

Now for a few dumb questions,

One each of the 3 power supplies there are 2 ELD's lit, is this normal or should all three LED's be lit?

I am using a Sun type 5 keyboard that worked fine with my Sparcstation 5, the power key does work, should the keyboard make a difference?

I popped the side cover off and found some status LED's behind the SCSI array, it looks like only the +5V one is lit, is this normal?
What am I doing wrong here?

As far as I can recall, the power key on a type 5 keyboard should work with the 450.

Do you have this document:
