Reset MGC passwords
A.K.A "Reload Default Accounts"
When replacing an MGC with one from another system, the passwords might be unknown. We will have to reset the user accounts before mgcsetup can be run. Physical access is required, as the MGC's faceplate reset button must be pressed when prompted.
Procedure:
- Connect via serial TTY (9600, 8N1)
- At the Username prompt type: resetCAUTH
- Ctrl-LDB, login as user: pdt2
- Enter mgcsetup
TTY output:
