In this application, a Redundant Switch is used with two identical Smart-UPS and PowerChute plus. In
networking environments where redundant drives, processors, and power supplies are commonplace, mirrored
power protection configuration should be a major consideration. Protection: Both Smart-UPS will provide
continuous EMI/RFI filtering and surge suppression. Battery backup is available in case of a primary or
redundant AC source failure. In case of a severe power event, the redundant Smart-UPS will continue to
support the load and also provide graceful shutdown to Windows NT, Novell and Solaris based operating
systems. Power monitoring and management is available with PowerChute plus software and APC
accessories. In this configuration, the Redundant Switch also has an Emergency Power Off (EPO) connector
which allows the Smart-UPS to be switched off by a remotely operated EPO control. Such a configuration is
common in computer rooms and laboratories where, for safety reasons, power to the loads may
need to be disconnected.
Redundant Switch Configuration Table for Best Application
Redundant Switch Model Voltage Rating Power Rating of Load Recommended Smart-UPS
SU043 230V 1400VA (2) SU700, (2) SU1000, (2) SU1400
