6800-24 password reset problem

Post by keiskis » 31 Jan 2013 03:49


I'm trying to reset the password on a couple of old 6800-24 switches, but when I boot to the VxWorks prompt and try to change the boot parameters to get to the miniboot, I'm presented with an "i2cWriteEEPROM failed in sysEEPROMSetBootline" error. The same thing happens on both switches, but I don't think it's because of a faulty EEPROM. Could this be somehow related to the fact that the two switches were once stacked together?

Any help would be greatly appreciated, as I've been looking everywhere for an answer to this problem, but so far to no avail.

Here's a capture of the boot process (user input is marked in blue) :
