If your box is an HP-UX you can:
Reboot the machine. During boot, interrupt the process on the console by hitting space when prompted. Type 'boot' and when asked "Interact with ISL?" answer yes. At the ISL prompt enter "hpux -is". The machine will then boot into single user mode right to a command prompt. You can then change the root password and reboot to get the machine back into multi-user mode.
#boot pri isl
ISL>hpux -isl boot
And interact with the IPL ---> YES
If your Box is a SunSolaris then I think it is ctrl + A to interrupt.

REBOOT(2) System Calls Manual REBOOT(2)
NAME
reboot - close down the system or reboot
SYNTAX
#define _MINIX_SOURCE 1
#include <unistd.h>
int reboot(int how, ...)
DESCRIPTION
Reboot() is used to close down the system. It allows several ways of shutting down depending on how:
reboot(RBT_HALT)
Halt the system and return to the monitor prompt.
reboot(RBT_REBOOT)
Reboot the system by letting the monitor execute the "boot" command.
reboot(RBT_PANIC)
Cause a system panic. This is not normally done from user mode, but by servers using the sys_abort() kernel call.
reboot(RBT_MONITOR, code, length)
Halt the system and let the monitor execute the given code of the given length. (code is of type char * and length of type size_t.)
reboot(RBT_RESET)
Reboot the system with a hardware reset.
Reboot() may only be executed by the super-user.
DIAGNOSTICS
If the call succeeds, it never returns. If something went wrong, the return value is -1 and an error is indicated by errno.
SEE ALSO
shutdown(8), reboot(8), halt(8), sync(1).
NOTES
Minix can not return to the monitor if running in real mode, or if started from MS-DOS. This means that most of the reboot functions will
change to a reset.
