Chapter 8 Redundancy

This chapter describes the Eaton Intelligent Power Manager (IPM) redundancy features.

The Eaton IPM can supervise composite devices. Composite devices are virtual nodes composed of two or

more UPSs mou

nted with specific redundancy topologies and a dedicated redundancy level.

NOTE Specific redundance topologies include Redundant supplies, Hot standby, Static

transfer switch (STS) for two components, and Parallel for two or more

components.

Enabling Redundancy

This Redundancy feature is enabled from Settings > System > Modules Settings (see Figure 108). After the

feature is enabled, the Eaton IPM performs the following:

Supervise composite devices (if the Redundancy feature is activated)

Shut down the Eaton IPM computer when a composite device is set as the power source and if the

shutdown feature is also activated.

NOTE You can also shutdown a remote server linked to the composite device through the

infrastructure connector feature.

Electrical Redundancy Schemas

Figure 109 to Figure 112 illustrate the electrical redundancy topologies.

Redundant supplies (such as dual feeds or triple feeds): Figure 109 illustrates a scenario when two UPSs

provide power on one or several multiple-feed servers.
