Always search the manual before posting.

If you can get into the device via winbox and then open new terminal or if you can get in through telnet or ssh. Then the command is "system reset" there is also usually a switch or a copper connection spot you can touch together to do the same thing. But I highly suggest the command line if at all possible it is much easier and I have seen people kill their hardware by not being careful
