Has (2) NEMA 5-15 receptacles for load(s).

Has (1) NEMA L5-30 receptacle for load(s)

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 considera-

tion. Protection: Both Smart-UPS will provide continuous EMI/RFI fil-

tering 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 avail-

able with PowerChute plus for Windows NT, NetWare, and Solaris-

based operating systems software and APC accessories. In this con-

figuration, 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.

Note: Smart-UPS 2200 VA and 3000 VA units used with Redundant

Switch models SU042-1 and SU042-2 require an additional backplate.

For each UPS, order the appropriate backplate, as listed below:

Tower units: SU027

5U Rack Mount units: SU027RM

3U Rack Mount units: SU027RM3U

Because its design is so flexible, Redundant Switch has many

uses. View or download the Redundant Switch Applications Guide

from the Products section of APC’s Web page.
