UPSs powering a server with multiple power supplies:
z
Some simple combinations of these electrical associations are also supported by Network Shutdown
module.
Important: To know the list of multi-UPS configurations that are supported by the Network Shutdown
Module, please refer to the appendix
List of tested multi-UPS configurations .
The Network Shutdown module doesn’t take into account the real electrical drawing. It computes dynamically
the minimal number of UPSs below which the system has to be shut down.
This minimal number of UPSs is recomputed permanently according to the following parameters:
z
the nominal load of each UPS
z
the output load level of each UPS
z
the UPS remaining backup time of each UPS
When several UPSs electrically power the computer hosting Network Shutdown Module, the main interface is
as follows:
