Connecting generation 1 or 2 FortiGate 6000F PSUs to low line AC power

If you connect a generation 1 FortiGate 6000F or a generation 2 FortiGate 6000F PSU to low line AC power, each PSU provides 1500W AC and at least two PSUs (PSU1 and PSU2) must be connected to power. PSU3 is a backup PSU and provides 2+1 redundancy. All PSUs should be connected to AC power.

See FortiGate 6000F series back panel for locations of the PSUs.

Recommended FortiGate 6000F low line AC power fully redundant configuration:

  • Two FortiGate 6000Fs (Unit 1 and Unit 2) in a High Availability (HA) configuration with two power feeds (Feed A and Feed B).
  • Connect PSU1 and PSU2 of Unit 1 to Feed A. Connect PSU3 of Unit 1 to Feed B.
  • Connect PSU1 and PSU2 of Unit 2 to Feed B. Connect PSU3 of Unit 2 to Feed A.

For normal operation of a FortiGate 6000F connected to low line AC power, at least 2 PSUs must be operating and connected to power. If two PSUs fail and only one PSU is operating, the FortiGate 6000F will continue to operate but only four FPCs will be running, the remaining FPCs are shut down. This means the performance of the FortiGate 6000F is reduced until at least two PSUs are connected.

Note

If only one PSU is operating, the FortiGate 6000F shuts down the FPCs starting with the FPC with the highest slot number, until only four FPCs are running. Usually this results in the FPCs in slots 1 to 4 running if there is only one PSU connected.

If one of the FPCs in slot 1 to 4 has previously shut down, the FortiGate 6000F keeps the four operational FPCs in the lowest slot numbers running. For example, if the FPC in slot 2 has previously shut down, if only one PSU is operating, the FPCs in slots 1, 3, 4, and 5 continue running.

The FortiGate 6000F also keeps the primary FPC running. Usually the FPC in slot 1 is the primary FPC, so if only one PSU is operating, the FPCs in slots 1 to 4 continue running. However, if the FPC in another slot has become the primary FPC, then this FPC as well as the three remaining FPCs with the lowest slot numbers will continue running. For example, if the FPC in slot 6 has become the primary FPC, then when only one PSU is operating, the FPCs in slots 1, 2, 3, and 6 continue running.
