If the BPX Switch is a late model, then a 19.2 Gbps backplane is installed. You can verify this by
running the dspbpnv command which will display "Word #2 =0001" if the backplane NOVRAM has
been programmed. If anything else is displayed, you'll have to visually check the backplane for the
fuses.
If the backplane is a 19.2 Gbps backplane, but the backplane NOVRAM has not been set to display
Word #2 =0001, then you can use the cnfbpnv command to program the NOVRAM.
To use the cnfbpnv command to program the NOVRAM:
Enter cnfbpnv. The response is:
Step 1
Are you sure this is a new backplane (y/n).
Step 2 Enter y
Step 3 Confirm that the change has been made by entering dspbpnv to confirm the response:
Word #2 =0001
Note
Step 4 Enter switchcc so that the change will be recognized by the switch software.
