Redundant Ac-Power Environment Requirements; Maximum Heat Output Of Each San Volume Controller 2145-Cf8 Node; Maximum Heat Output Of Each 2145 Ups-1U - IBM 2145-CF8 Hardware Installation Manual

Dimensions and weight
Ensure that space is available in a rack that is capable of supporting the node.
Additional space requirements
Ensure that space is also available in the rack for the following additional space
requirements around the node.
Maximum heat output of each SAN Volume Controller 2145-CF8
node
The node dissipates the following maximum heat output.

Maximum heat output of each 2145 UPS-1U

The 2145 UPS-1U dissipates the following maximum heat output.

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.
