Hi,
I have a legacy 4006 Chasis with a SUP3, recently started giving
issues. I know it's EOL, and more than likely needs to be replaced,
but any assistance if possible, would be appreciated.
I'm getting CRC32 errors for NVRAM, always at byte 0x54000000
i.e.
Switch#sh ver

Is the SUP pretty much dead? Everything is still running fine from
the face of it, but I'm really concerned about these errors....
