I have 2 stargates working and a third for a spare.

Currently one of them has a problem.  turning it on left led flasshes and then goes out.  other 3 keep flashing.  I cannot connect to winevm no comm, but ports and cables work on other units.  I measured Vcc and it reads 5.5.  12v read 12.8 on this unit.  working units have 4.9v and 12.3v.  This unit is 22 years old without failures.


Caps look ok but?

Any thoughts would be appreciated.

Thanks,
Al

A couple of things to check are the MAX serial chips to restore communications and, if you can do that, try loading the f/w again.

Thanks will try that tonight if I have any.  Appreciate the input still curious about the Vcc votages will need to get some caps.  1k at 35v and 470at 16 need to check spacing.

Thnaks very much.

Could  be because of the possible chip issues.
The load on the power supplies is lower and the voltage is slightly higher.

Hi,

Just a thought that could be related... 

I've had my Stargate since 1997.  I drove down to JDS and picked it up from Jeff as UPS was on strike at the time.

I have been very impressed that my original unit has been in service since that time.   I did have a couple of WebX units die on me, but was able to repair one of them (bad daughter card component).   

In the next month, I plan to recap my two Stargate boards as there's no way those aluminum capacitors are anywhere near specification after all of these years.  If your Stargate is having issues, there's a good chance the capacitors need to be replaced, so don't toss your unit.  It's an easy task, even if you haven't done much/any soldering in the past.

Not a bad idea but I live by the "if it ain't broke don't fix it" mantra. But a very good point particularly if there's a problem!
