FortiGate-7060E Chassis
DC Power Supply Units (PSUs) and supplying DC power to the chassis
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 Power Supply Units (PSUs) and supplying DC power to the chassis
The DC version of the FortiGate-7060E 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
FortiGate-7060E front panel on page 5
for locations of the PSUs. The diagram shows AC
PSUs, with a DC version of the chassis the AC PSUs are replaced with DC PSUs.
Each PSU is designed to be installed in a Telecom data center or similar location that has available -48VDC
power fed from a listed 40A circuit breaker. To improve redundancy you can connect each power supply to a
separate power circuit.
DC power cables are intended to be used only for in-rack wiring, must be routed away from sharp edges, and
must be adequately fixed to prevent excessive strain on the wires and terminals.
DC terminals accept UL approved ring terminals for 8/M4 stud with ext ring diameter < 9.8 mm. DC cables must
be a minimum of 8 AWG.
The following table lists some key power data for each PSU.
