Hi bezoid, Daisy chaining the devices is not supported. The USB and serial options are designed for a single connection. You could try a USB hub or a serial port switch, but these have not been validated and may not work properly with the multi UPS management software.
Goal  - Establish monitoring on nine Dell UPS that do not have management cards. Is it possible to daisy chain the USB  or Serial (RS-232) ports on Dell UPS?  Trying to get monitoring via Dell UPS Management Software setup on eight Dell UPS 1000Ws and one Dell UPS 3750W.  The eight UPS are racked together, but none of them have a management card installed.  I am trying to figure out if it is possible to daisy chain the USB or Serial ports, or do I need to connect each UPS to its own USB or Serial port on a server/PC? [IMAGE] Thanks!
