I have two identical model Tripp Lite SU2200RTXL2UA UPS units in a rack in a building with a generator. The line power failed and the generator came online. When the line power came back online the generator switched off. It appears the UPS units didn't like the power issues as both of them shutdown. I did try turning them back on but the front panel is dark. Is there a procedure for doing a hard reset on this model of Tripp Lite UPS?
