Mike,
If you feel afraid of the next power outage, why not install a more
powerfull UPS with a longer run time? Or, as it is in my case, a friend
of mine substituted the factory default battery in the UPS with a car
battery, that holds the Server for 4-5 hours. Add another battery and it
will hold 8-9 hours.
Really funny but it works.
Regards,
Tigran

How reliable is Digium hardware in general.? My new TDM400P just died.
I have a number of Digium T1 products (T100P, TE410P, TE405P and
TE406P) as well as a few TDM400 based boards. No failures in the
last 2 years or so.
So, at over 2x the cost is Sangoma hardware more sturdy than the Digium
stuff?
Not that I've seen. I also have a number of Sangoma products. Both
work very well for me. As an engineer, I can also see that the
protection on the interfaces is comparable.
Mike (totally UNimpressed with Digium)
I don't think this is a Digium problem, at least not yet. What did
their customer service people say? Can you ask for a failure
report? You note that power went out. Generally when this occurs
there is a very high chance of transient voltage spiking or line
swells not only on the residential electrical power grid but also on
the telephone network. Do you have any telco line protection in
place to protect the card from nasties coming in from the outside?
Is the protection correctly installed? How about electrical
protection? The MOVs in your power strip and UPS are only good for a
few hits before they become ineffective (something they never tell you).
Unless you know something more than you've presented here it is a
little premature to start pointing fingers.
-A.
Point taken. I was not so much point fingers but asking what my
expectation should be and maybe shedding some frustration. I don't
really have a lot of experience with this kind of communications gear
and it could very well be that one should keep spare daughter boards
in stock.
I was finally able to get the thing going again but I do not know what
I did to accomplish that. I had tried the card in different PCI
slots, reseated the daughter cards, powered the machine with and
without the card, checked BIOS settings then after half a day of
fiddling it just started responding again. Who knows what the problem
was?
As far as heat and stuff go, the card is in the only card in a new
IBM/Lenovo box and has plenty of air on all sides. The box itself is
powered by an AVR type UPS, which according to the graphs it shows is
keeping the power pretty stable even though dips.
One weakness is the incoming PSTN line, what is the best way to
protect that beyond the device at the premises entry ?
So now it appears to be working again, don't know what failed, don't
know what made it work. and afraid of the next power outage at this
rural SOHO.
Mike
