Due to hardware and firmware changes necessary to make the Symmetra Power Array 3:1 system function properly, it requires specific intelligence modules and power modules.


The Symmetra Power Array 3:1 has new power modules as well as new main and redundant intelligence modules.  You will need to ensure that the modules you are installing are compatible using the following information.

The new power modules will work in both the Symmetra Power Array 3:1 and the Symmetra Power Array 1:1  The part number is still the same (SYPM). The new SYPM is identifiable as it has a different Firmware Revision number and frame color compared to the old SYPM. The MIM tells the SYPM to work in single phase mode or 3 phase mode.

How to Identify a SYPM that is compatible with Symmetra Power Array 3:1:

  • Serial numbers begins CD9910 or later
  • The new SYPM's Firmware Revision is rev 300 or higher.

  • On the front of the SYPM, to the left of the fan you will see the specifications sticker (approvals and operating parameters). This sticker has a silver color on the new SYPM and a cream color on the old SYPM.

Please Note: The old SYPM's will not work in the Symmetra Power Array 3:1. If an old SYPM is put into a Symmetra 3:1 it will not turn on and will be reported as off and failed by SYMIM2 in PowerView. The following table shows what is supported:
