Can't bring E25K system controller to OK prompt

Hi,

Due to some changes at our company, we lost the password for the root and sms-svc account on the primary system controller (E25K).

We connected a serial console to the system controller but we never managed to break the session to bring it to the OK prompt.
(tried: ~#, [ENTER]~[CTRL] b, ~[CTRL][BREAK], [CTRL][BREAK], [CTRL] a b, [SHIFT]-#, sending break from terminal option, unplug/plug keyboard from serial console client, etc.)

As the system controller failover is not enabled, we can't rely on the other system controller... I know it's bad practice and it's really dumb to loose the passwords... but probably you all know how it goes in these huge IT companies where systems are managed by teams of people.

My questions are:
1.) Is there any other way to break into the OBP?
2.) Is there any way to force the secondary SC to take over the role of the primary, while not having access to the primary?

Cheers!

iscc(7) 						 Miscellaneous Information Manual						   iscc(7)

NAME

       iscc - serial communications interface

SYNOPSIS

       controller  iscc0  at  isa0

DESCRIPTION

       An  onboard  Zilog  8530  DUART	provides  AXPvme-based Single Board Computers with console (CON) and auxiliary (AUX) serial communications
       ports.  Both serial communications ports can operate at baud rates from B50 to B38400,  excluding B134 (see tty(7)).

       On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01)	is
       available for use by application programs as an additional communications port.

       In  the	absence  of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial
       system console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity.

       Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs.

RESTRICTIONS

       Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured	as
       the serial system console. The iscc terminal driver enforces this restriction.

       No modem control is supported for either the CON or AUX serial communications ports.
