When connecting to the 2145 UPS-1U, use only the power cable assembly, part
number 31P1294, that was supplied with the node. Power cable assemblies that
were supplied with previous SAN Volume Controller models do not work with
the 2145-CG8 model because there are two power cables in the bundle for the
2145-CG8 model. The correct part is differentiated by the blue tape that binds
the cables together.
Before you begin this task, see the completed customer's cable-connection table,
which is described in the
IBM System Storage SAN Volume Controller Planning Guide

Use the information in this table to identify the 2145 UPS-1U unit to which this
node is to be connected.
