Server power summary

ServerPSU 1 connectionPSU 2 connection
INT-SBS216-2 2U firewall PDU1 · slot 6 PDU1 · slot 7
cesi-bhyve01 2U server PDU1 · slot 1 PDU2 · slot 2
multi-bhyve/store02 4U server Yellow-side inverter PDU1 · slot 4
multi-bhyve/store03 4U server Yellow-side inverter PDU2 · slot 5

Note: only the firewall has both PSUs on the same PDU (PDU1). Both bhyve servers and both 4U storage servers split their PSUs across two independent power sources, so a single PDU or inverter failure won't take a fully redundant server down.
