In this application, the Redundant Switch is connected to two separate

AC sources. Loads with single or multiple power cords can now have

N+1 power paths, to deal with a single AC source failure. The AC

sources can originate from a centralized UPS, a generator set, or even

separate utilities. Protection: This application protects against failure of

one of the two AC sources. These problems can range from a tripped

circuit breaker, to a utility blackout, to a centralized UPS failure.

In this application, the Redundant Switch is connected to two separate AC

sources. A single Smart-UPS is then connected to the Redundant Switch,

providing the Smart-UPS with dual AC input feeds. Protection: A Smart-UPS

in the power path will provide full-time surge suppression and provide bat-

tery backup if both of the AC sources fail. The Smart-UPS protects against

brownouts, blackouts and overvoltages. The Smart-UPS also provides

graceful server shutdown, power monitoring and power management.

Mirrored UPS Protection

With dual input power cords, the Redundant Switch

has the ability to source power from one of two sep-

arate AC circuits. The Redundant Switch continu-

ously monitors both AC circuits and will switch auto-

matically from the primary to the redundant AC

source. The seamless transfer to the attached loads

ensures the availability of continuous AC power as

well as safe server shutdown. The Redundant

Switch also provides user-configurable settings for

low voltage and AC line distortion, in order to meet

the power requirements of your site.

The Redundant Switch can be easily installed in any

19” equipment rack, occupying just one U (1.75”) of

rack space. It can also be mounted in the rear or

side of the rack, requiring zero U of rack space. It

ships with all appropriate rack-mount hardware for

two and four post racks.

Implementing Your Solution

Because its design is so flexible, there are numerous

configurations for the Redundant Switch, providing

different levels of availability. Three are outlined

below: Good, Better, and Best.
