As shown in Figure 1, the CX4-120, CX4-240, CX4-480 SPE uses two 1.2-kilowatt SPSs to maintain power to the storage system during a power loss; this allows a full dump of the write cache to a reserved area on the persistent disk. In the case of the CX4-120, CX4-240 and CX4-480, SPS power output connectors are used to power the SPE as well as to power the first DAE on the first back-end loop.

It is important to cable each SPS so it connects completely to either the A side or the B side. For example, if you are looking at the SPS from the back, they should be configured as follows:
- SPS on the right: Power-out and sense cables should connect to power supply A and SP A.
- SPS on the left: Power-out and sense cables should connect to power supply B and SP B.
If an SPS is cabled with the SPS sense cable going to SP A and the power-out cable going to power supply B (or vice versa), error conditions are displayed when the SPS is tested while it is charging.
