asterisk users - Jul 2005 - Melting TDM card

Yesterday FedEx brought me my new TDM400P with 4 FXS modules.  I installed
it (in the correct type PCI slot) , plugged in the power, and fired up the
system.  A few minutes later everyone in the office is complaining about
something burning.  I open the server again, and the top of the Digium card
is black, slightly deformed, and looks and smells of melted plastic.  The
funny thing is.the card still works just fine (as far as my testing has
revealed, anyway.  I haven't tried ringing the lines, just placing calls
from them).  Maybe this is how Digium knows if a card is returned used or
not?

 

Still, nothing was touching the card, it was in the right slot, and it was
installed as instructed.  Beats me what happened.  I'm just not sure I like
spending hundreds of dollars on a card that arcs and melts when I install it
- even if it continues to work.

 

Has anyone else had this problem with the TDM cards?

This is clearly a case for Digium tech support.  Do you honestly think that 
this is normal?  I've installed dozens of these cards over the past year or 
so and never run into it.

It almost sounds like a grounding issue between the telco lines and the PC.

-A.

Call Digium support, it's a brand new card and the mailing list 
certainly can't help you with it.

I had the problem on a very old version of the TDM card (brown card)  I
contacted Digium and after a few WTF's they sent me a shiny new blue
card that to this day is still blue!!!
 
Contact your reseller or Digium directly they always stand behind their
products. 
 
I would double check for ground loops and good connectivity on the molex
connector.
