Compaq Engineering has not tested any 3rd party brands of Uninterruptible Power Supplies with the Neoserver so we have no compatibility information available. Do not know if the OS will be shutdown correctly by a serial signal from the Tripp Lite UPS.

Can you use another brand UPS, i.e. Tripp Lite OfficePro500 which supports SCO UNIX and has similar capacity and serial connectivity?
