Power for Kria is 5V but SM delivers 12V. Need a hefty DC/DC.

Enclustra has e.g. XCZU7EV-2FBV900 (we ordered ME-XU8-7EV-2I-D1 on 3/27/20)

Ethernet on Rev 2a:

• ESM has 6 ports
  • SGMII 0 - front-panel RJ-45 via PHY on SM
  • SGMII 1 - not used
  • PHY 0 - Zynq port 1
  • PHY 1 - ATCA A
  • PHY 2 - ATCA B
  • PHY 3 - IPMC
• Enclustra has 2 ports wired:
  • PHY 0 - rear mag jack
  • PHY 1 to ESM PHY 0

So on the adapter ideally there would be two PHY, but DP83867 are unobtainable (72 weeks lead time!). If we just want to test all the GPIO etc we could operating without a PHY to the adapter for some time. We do need Ethernet to the Kria though. What about an SFP?
