AC power supply units (PSUs)

The FortiGate-6000F back panel includes three hot swappable AC power supply units (PSUs). At least two PSUs (PWR1 and PWR2) must be connected to power. PWR3 is a backup power supply and provides 2+1 redundancy. See FortiGate-6000F back panel for locations of the PSUs. All PSUs should be connected to AC power.

Recommended 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). FortiGate-6000F supports HA with two and only two FortiGate-6000Fs.
  • Connect PWR1 and PWR2 of Unit 1 to Feed A. Connect PWR3 of Unit 1 to Feed B.
  • Connect PWR1 and PWR2 of Unit 2 to Feed B. Connect PWR3 of Unit 2 to Feed A.

For normal operation of a single FortiGate-6000F, 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.

Use a supplied C15 power cable 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.

Hot swapping an AC PSU

Follow these steps to safely hot swap an AC PSU.

Caution You can hot swap a PSU without affecting performance or interrupting traffic as long as two PSUs remain connected to power at all times. If you need to hot swap one of two operating PSUs performance will be affected while only one PSU is connected.
  1. Attach an ESD wrist strap to your wrist and to an ESD socket or to a bare metal surface on the chassis or frame.
  2. Turn off the power being supplied to the power supply and disconnect the power cord.
  3. Press the latch towards the handle until the PSU is detached then pull it out of the chassis.
  4. Insert a replacement PSU into the chassis and slide it in until it locks into place.
  5. Connect the PSU power terminals as described above.
  6. Turn on power to the PSU.
  7. Verify that the PSU status LED is solid green meaning that the PSU is powered up and operating normally.

PSU LED states

State Description
Off DC power not connected.
Flashing green The PSU is in standby mode, not supplying power to the chassis.
Green Normal Operation with DC power connected.
Amber Input voltage outside of normal operating range, PSU fan not operating, or output voltage outside of normal operating range.
Flashing amber Warning that power input or output is close to outside of normal operating range. PSU should be replaced.
