FortiGate-7000F chassis
Fortinet Technologies Inc.
AC PSUs and supplying AC power to the chassis
The FortiGate-7000F chassis front panel can include up to eight hot swappable 200-240V, 10A AC PSUs. The capacity
of each PSU is 1800W (90% of full capacity of 2000W). See
FortiGate-7000F back panel on page 9
PSUs.
The number of PSUs required by a chassis depends on the number of FIMs and FPMs in the chassis. For example, a
FortiGate-7000F chassis containing two FIMs and six FPMs requires four PSUs to provide a total of 7200W. A chassis
containing two FIMs and ten FPMs requires six PSUs to provide a total of 10800W. You can add extra PSUs to provide
redundancy. See
Power consumption for different FortiGate-7000F configurations on page 17
If the chassis does not have enough power because PSUs have failed or become disconnected, the active SMM will
begin shutting down FPMs starting at the highest slot number.
All PSUs should be connected to AC power. To improve redundancy you can connect each PSU to a separate power
source.
Use a C15 Power cable, supplied with the chassis, to connect power to each PSU C16 power connector. C15/C16 power
connectors are used for high temperature environments and are rated up to 120°C.

The PSU LED indicates whether the PSU is operating correctly and connected to power. If this LED is not lit, check to
make sure the PSU is connected to power. If the power connection is good then the PSU has failed and should be
replaced.
Power consumption for different FortiGate-7000F configurations
The tables in this section provide information about how to calculate maximum power consumption for a FortiGate-
7000F system with two FIM-7921Fs and with four, six, or ten FPM-7620Fs.
Power consumption calculation with six FPMs
The following table shows that a FortiGate-7000F with two FIM-7921Fs and six FPM-7620Fs would require a power
allocation of 6890W. The capacity of each PSU is 1800W (90% of full capacity of 2000W). The system would require four
PSUs (1800 x 4 = 7200W). You could add up to four extra PSUs for redundancy.
