I was just going to point that out about the reed relay. It was always marked "pressurized-do not open". I think that pressure was the only safety hazard though, as in the risk of the thing blowing glass all over you if you tried to pry it open. I learned the hard way on one when I was a kid and I assure you, there was no green goo in it, just a coil of wire surrounding a glass tube containing two sets of reed contacts.

The 400D cards were Mil-Spec and I doubt very seriously that there is anything to be concerned over. I must agree with most people here that the goo is coming from an outside source, such as a water leak or a concentration of humidity in the area.

:shhh:

Hey metelcom!

Nice 620 panels

We finally had the green liquid analyzed by a lab, nothing hazardous detected. No PCB's or heavy metals. So, the liquid will remain a non-hazardous mystery.

Thanks again for all the feedback and posts.

I will definitely keep this site bookmarked for future telecommunications issues.

Thanks for letting us know.

Thanks env guy. BTW, has anyone seen my green lollipop ????

I've noticed the same green goo on other 1A2 systems, usually on or under the power supply with no other apparent sources. It's a thick liquid, probably from a capacitor. I wouldn't eat it, but it's nothing to worry about in a non-functioning system.

It looks like your power supply is directly over the goo, so that's probably the source.

I too have a system with 400D cards with "green goo." It seems to be coming from a rectangular box labeled Western Electric 327A Delta = 72K. Is this the reed relay? The green goo is extremely viscous, almost like melted plastic. My concern is the same as env guy as my newly pregnant wife was the first to discover the goo after having unknowingly come in contact with it and having had it on her skin for ~30 minutes. Any help or insight would be greatly appreciated.

Thank you,

Hi Bill,

Since he never identified the source of the goo, in the event that it's from a different component, any chance you know what the part labeled "Western Electric 327A Delta = 72K" is? The delta symbol is actually an upside down Delta.

Many thanks,
Rhett
