Problem

You want to burn firmware into an IPX, IGX, or BPX card, but the card resets due to hardware failures. The resets result in the burnfwrev command process aborting.

Solution

To successfully burn the card with the new firmware, even though the card may still suffer from hardware failures with the new firmware, use the cnffunc command to change the automatic card reset on hardware errors from enabled to disabled. The following example shows that the automatic card reset on hardware errors is disabled:

11    Disabled  Logging SVC Connection Events 
12    Disabled  Force Download From a Specific IP address 
13    Disabled  CDP WinkStart Signalling 
  
Last Command: cnffunc

Note: On the BPX, and other versions of switch software, the Automatic Card Reset on Hardware Error option is not always number 4.

Remember to change this setting back to Enabled when the card has completed the burnfwrev command process.
