The redundant ac-power switch requires two independent power sources that are
provided through two rack-mounted power distribution units (PDUs). The PDUs
must have IEC320-C13 outlets.
The redundant ac-power switch comes with two IEC 320-C19 to C14 power cables
to connect to rack PDUs. There are no country-specific cables for the redundant
ac-power switch.
The power cable between the redundant ac-power switch and the 2145 UPS-1U is
rated at 10 A.
Redundant ac-power switch specifications
The following tables list the physical characteristics of the redundant ac-power
switch.
Dimensions and weight
Ensure that space is available in a rack that is capable of supporting the redundant
ac-power switch.

Maximum weight
43 mm (1.69 in.)
192 mm (7.56 in.)
240 mm
2.6 kg (5.72 lb)
Additional space requirements
Ensure that space is also available in the rack for the side mounting plates on
either side of the redundant ac-power switch.

Heat output (maximum)
The maximum heat output that is dissipated inside the redundant ac-power switch
is approximately 20 watts (70 Btu per hour).
Cabling of redundant ac-power switch (example)
You must properly cable the redundant ac-power switch units in your
environment.
Note:
While this topic provides an example of the cable connections, it does not
indicate a preferred physical location for the components.
Figure 17 on page 19 shows an example of the main wiring for a SAN Volume
Controller cluster with the redundant ac-power switch feature. The four-node
cluster consists of two I/O groups:
v
I/O group 0 contains nodes A and B
v
I/O group 1 contains nodes C and D
