As shown in Figure 1, the VNX5700, VNX7500 & CX3-80 SPE uses two 2.2-kilowatt 2U 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 078-000-050, 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.
**Please note: EMC VNX5700, VNX7500 & CX3-80 2200W 2U SPS Replacement Battery is not a UPS**
The SPS is just to protect the write cache. I am saying "just" because this component is not an UPS at all. If there is a power failure it will allow the cache to be flushed to the vault disks hence avoiding data to be lost/corrupted. This process is only a few minutes..T-support team.
