DSP2 card fault data debug collection
Background:
Dialogic® Digital Signal Processing Series 2 Card (DSP2) and Digital Signal Processing Series 2 Plus Card (DSP2 Plus) running Dialogic® Converged Services Platform (CSP) Release 8.4.1 or greater have the ability to capture fault log data using a debug terminal in the event that the card faults. In addition, a file can be written to the NFS server if the DSP2 card has NFS configured.
This data allows Dialogic to diagnose the root cause of the fault.
Procedure - using the debug port:
The following describes how to collect the fault data from the DSP2 or DSP2 Plus debug port in the case the card has faulted and the NFS server is not set up and configured.
1. Connect a terminal to the debug port of the DSP2 or DSP2 Plus card using the Debug Cable Assembly (Dialogic part code 64-0046-00 or 164-0046-00). Set the software terminal properties to 19200, 8, N, 1.
2. Type 'Shift + x' to enable print.
3. Type 'o' to enter the the
os> menu.
4. At the
os> prompt type 'f'. This places you in the fault menu at the
fault> prompt.
5. At the
fault> prompt type 'u'; you will then be prompted to enter the format you want. Either option 'R' to print to the debug screen or 'N' to write a file out to the NFS server.
Procedure - using NFS
If the NFS server is configured and online then once the DSP2 or DSP2 Plus card faults the write to NFS will take place automatically when the DSP2 or DSP2 Plus card comes back online.
The file that is written is located in the root of the mount point in which it was configured.
The file name of the fault data file contains the serial number of the DSP2 or DSP2 Plus card followed by a date and time stamp and the flt file extension; for example:
46990_20090611101728.flt
An example fault data file
is attached.
Alarms are generated indicating that the write to NFS of the fault data was successful or not successful.
Below are examples of the two possible alarms. This information can also be found in the Dialogic® Converged Services Platform (CSP) Release 8.4.1 Documentation
CSP API Reference.
