Symptoms and Solutions
DSP Download Failure
Use the PXM dsplog command to determine if the minimum number (five) of the DSPs failed to
download. The terminal displays results similar to the following:
NODENAME.1.7.PXM.a > dsplog
01/01/2001-00:02:10 05 tDspmDl VISM-6-9193
DSPM task errors : 6 DSPs failed to download
If the number of DSPs (six in the above case) is greater than five, the card will fail to be in the active
state. If this condition happens repeatedly, replace the card.
Use the following PXM dspcds command, and the results, to determine the current state of VISM DSPs:
NODENAME.1.7.PXM.a > dspcds
