Chassis (fans, SMMs
etc)
To completely power a FortiGate-7000F with two FIMs and six FPMs you would need four PSUs. You can add up to four
more PSUs to provide 4+1, 4+2, 4+3, or 4+4 redundancy.
Power consumption calculation with ten FPMs
The following table shows that a FortiGate-7000F with two FIM-7921Fs and ten FPM-7620Fs would require a power
allocation of 9754W. The capacity of each PSU is 1800W (90% of full capacity of 2000W). The system would require six
PSUs (1800 x 6 = 10800W). You could add one or two extra PSUs for redundancy.

To completely power a FortiGate-7000F with two FIMs and ten FPMs you would need six PSUs. You can add one or two
more PSUs to provide 6+1 or 6+2 redundancy.

Power distribution unit (PDU) requirements

Due to the power consumption FortiGate-7000F, Fortinet recommends the following PDU requirements if you are
operating a FortiGate-7000F 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 .
l
One 40A/208V/3ph, 1x PDU required and 3xPSU @ L1/L2, 3xPSU @ L2/L3, 2xPSU @ L1/L3. No extra load on
l
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.
