Supplying power using the FortiGate-5053B power supply shelf
and PSU-5000B power supplies
If DC power is not available at your location, you can use the FortiGate-5053B and
FortiGate-5053B-LC 1U 19-inch rack mount power supply shelves with PSU-5000B hot
swappable power supplies to convert AC power to DC power. These components are not
supplied with the FortiGate-5140B chassis and must be purchased separately.

As already stated, Fortinet supplies four 3-ft. power cables with AWG-6 stranded wires
and double-hole lugs: Black for -48VDC and red for RTN. These cables should only be
used to connect the FortiGate-5140B PEMs to a FortiGate-5053B power supply shelf if
purchased with your FortiGate-5140B chassis. The double-hole lugs to be connected to
the FortiGate-5140B PEMs include rubber boots that should be installed before
energizing the power system. If the power cable length needs to be longer than 3 ft.,
higher gauge wires should be used.
The FortiGate-5053B power supply shelf can include up to four PSU-5000B power
supplies. The power supply shelf can be connected to high line AC input (186-240VAC) or
low line AC input (100-185VAC).
•
When connected to high-line AC input, a single power supply can provide 2725W of
DC power and a fully populated FortiGate-5053B power supply shelf can provide up
to 10.9KW of DC power and 8175W of DC power with 3+1 redundancy with an output
voltage of 54 VDC.
•
When connected to low-line AC input a single power supply can provide 1200W of DC
power and a fully populated FortiGate-5053B power supply shelf can provide up to
4800W of DC power and 3600W of DC power with 3+1 redundancy with an output
voltage of 54 VDC.
The FortiGate-5053B power supply shelf edge controller controls and manages the
power supplies, provides for redundancy, and provides a control and alarm
communication interface for the power supply shelf.
For a more information about the FortiGate-5053B power supply shelf see the
5053B Power Supply Shelf Guide
.
To supply power to a FortiGate-5140B chassis you must connect one FortiGate-5053B
power supply shelf to one FortiGate-5140B PEM.
You can install extra PSU-5000B power supplies in a single FortiGate-5053B power
supply shelf to provide power redundancy. If a PSU-5000B fails or is removed a backup
PSU-5000B will continue to supply power.
For a completely redundant power supply you can connect a second FortiGate-5053B
power supply shelf to the second FortiGate-5140B PEM.
