Redundant AC-power environment requirements

Ensure that your physical site meets the installation requirements for the redundant AC-power switch.

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.

Table 1. Rack space required for redundant AC-power switch
Height	Width	Depth	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.
