 The telescope will run away and not stop if the NGTCS computer (on the west side of the telescope mount) dies while the telescope is moving. You **MUST** run over and hit the Emergency Stop button on the observatory control panel, which will kill power to the RA and DEC drive motors stopping the motion. If this happens telescope pointing will be lost and you will have to perform a hardstow.  Read about how to do this in the "what do do if you lose pointing" link.  The telescope will run away and not stop if the NGTCS computer (on the west side of the telescope mount) dies while the telescope is moving.
