Power distribution unit (PDU) requirements

Due to the power consumption FortiGate-7121F, Fortinet recommends the following PDU requirements if you are operating a FortiGate-7121F that contains two FIM-7921F and ten FPM-7620Fs.

  • Two 30A/208V PDUs with no other devices connected to the PSUs. Connect four PSUs to each PDU .

  • One 40A/208V/3ph, 1x PDU required and 3xPSU @ L1/L2, 3xPSU @ L2/L3, 2xPSU @ L1/L3. No extra load on PDU.

120V PDUs are not supported since high power PSUs are not designed to work under low AC line input. Max wattage and load balancing across PSUs will be compromised if doing so.
