Redundancy
This chapter describes the Dell Multi-UPS Management Console (MUMC) redundancy features.
The Dell MUMC can supervise composite devices. Composite devices are virtual nodes composed of 2
or more UPSs in redundant configuration (Redundant Supplies).
This Redundancy feature is enabled from Settings > System > Modules Settings (see Figure 80).
The Dell MUMC will then:
• Supervise composite devices (if Redundancy feature is activated)
• Shutdown the Dell MUMC computer when powered by several UPSs (if shutdown feature is also
activated).

Figure 81 illustrates the electrical redundancy Redundant Supplies topology. In this case, the two UPSs
provide power on one or several multiple feed servers.
