I recently converted two SUP II modules from CATOS to IOS and all was well for the week after I converted them. I shut the switch down for three weeks and then attempted to use it recently and only one of the SUP II modules will boot. The problematic SUP follows the same pattern on every attempt to boot the switch. The switch will report a bad magic number 4 times and then successfully load the IOS and boot the SP. When the boot process is handed off to the RP, the switch drops into ROMMON. From here I can type confreg 0x2102 and then reset and the switch successfully reloads (most times). The switch also displays a message stating that the NVRAM is corrupted. I have read that a dead NVRAM battery can cause issues as this battery maintains a 4MB NVRAM that contains the files necessary to boot the switch. So here's the question - is this battery the likely cause of this issue? The battery is soldered to the board and although I can replace it, I would rather not attempt to do so if it's not the root cause of the problem. Any thoughts?
