DC PSUs and supplying DC power to a FortiGate 6000F
The DC version of the FortiGate 6000F includes two hot swappable -48 to -60 VDC, 50A max DC PSUs. Each PSU has an internal 60A/170VDC fast blow fuse on the DC line input.
Only one PSU must be connected to power. The second PSU is a backup PSU that provides 1+1 redundancy. See FortiGate 6000F series back panel for locations of the PSUs. The diagram shows three AC PSUs, the DC version replaces the AC PSUs with two DC PSUs in slots PSU1 and PSU2. PSU3 is covered by a metal panel.
Recommended fully redundant configuration:
- Two FortiGate 6000Fs in a High Availability (HA) configuration with two power feeds (A and B). FortiGate 6000F supports HA with two and only two FortiGate 6000Fs.
- On both FortiGate 6000Fs, connect each PSU to a different power feed.
For normal operation of a single FortiGate 6000F, only one DC PSU must be operating and connected to power. If only one DC PSU is operating, all components and all FPCs continue to operate normally. However, to maintain redundancy, you should replace a failed DC PSU.
Each DC PSU is designed to be installed in a Telecom data center or similar location that has available -48VDC power fed from a listed 50A circuit breaker. To improve redundancy you can connect each PSU to a separate power circuit.

Individual DC PSUs do not have to be connected to ground. Instead you can use the information in Connecting the FortiGate 6000F to ground to connect the FortiGate 6000F to ground. |
Fortinet supplies custom DC power cables that connect to the two-prong power connector on each DC PSU. The connector clicks into a release tab that secures the cable into place. DC terminal rings on the supplied cable must be securely and safely fastened to the your data center power supply terminals. The supplied 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.
