Dear all, We recently acquired a brand new AS DS25, with 2 power supplies (for redundancy reasons, we thought !). However we are now told that this machine needs both PS's in its 'basic' (i.e. non-redundant) configuration. There is a possibility to install a 3rd PS, but this can only solve the problem of a failing PS (one of the other 2 then). What we typically want to do is hook up 1 PS to the standard power-net, and another PS to a UPS-protected net, allowing us more redundancy AND the possibility to dynamically shut off 1 of both power-nets without shutting down the machine... However this last scenario doesnt seem to be possible in this DS25. Strangely enough, we have a 7 year old DS25 that DOES this, i.e. it has 2 PS, that can be connected to 2 different power-nets... Can anybody confirm these findings, and suggest any solutions ??? Marc Marc Thoelen Netwerkmanager Universiteit Hasselt Agoralaan, Gebouw D 3590 Diepenbeek
