Hello All,
Please let me know if you have any comments or suggestions how to resolve the following situation. My configuration is:
- Dell PowerEdge 1750 (standard), one CPU Xeon 3.0GHz
- TDM400P with 4 FXO, connected to 4 regular phone lines (PSTN)
- Asterisk 1.0.0 from cvs
- Zaptel and Zapata latest from cvs
[snip]
Afaik the preferred way is too use zaptel, libpri, asterisk and
asterisk-addons either from the stable branch (cvs co -r v1-0 <modules>)
or from HEAD (cvs co <modules>). You are mixing them. Get one or the
other.
Good point. Thanks.
Also make sure your Dell has the latest firmware installed for all
components they offer newer firmware for. Solved some funky problems I
dealt with a while back.
I am using latest firmware for all components.
If you get any NMI errors, BIOS memory count that's off and really weird
behavior, take out the memory modules and reseat them properly. Same
applies to the CPU. Might as well do any cards while you are at it. And
if you are really suspicious, check the seating of the cables too.
Reseating the CPU and memory modules solved all our remaining problems.
That was my routine procedure, too.
I have tried this Digium card in two 1750 servers, which were working fine for 3 months before. The NMI would be flagged on a server only at the precise moment when zaptel drivers are loaded. I am not too crazy about Dell's assembly quality, though it seems that Digium hardware / drivers are the only source of troubles here. It may be a compatibility issue as well.
Now I still have NMI when loading drivers, though the loud-noise problem did not appear for 24 hours now as I removed USB support from 2.4.27 kernel.
Thank you for your comment (the only one so far).
Sincerely, Andrei (MPI)
