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.
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.

DC PSUs and supplying DC power to the chassis

The DC version of the FortiGate-7040E chassis front panel comes with four hot swappable 48-72V to 12V 125A DC
PSUs. Each PSU has a Internal 60A/170VDC fast blow fuse on the DC line input.
At least three PSUs (power supplies 1, 2, and 3) must be connected to power. The fourth power supply is a backup
power supply and provides 3+1 redundancy. You can add a 5th power supply to provide a second backup power supply
and 3+2 redundancy. You can add a 6th power supply to provide a third backup power supply and 3+3 redundancy. See

You can hot swap a PSU without powering down the FortiGate-7040E as long as two PSUs
are connected to power and operating normally. If you need to hot swap one of two operating
PSUs, you must power down the chassis first.
