You can install multiple power supply shelves and multiple power supplies to provide additional power and for
redundancy.
For more information about the FortiGate-5053B power supply shelf see the
Guide .
As already stated, Fortinet supplies eight 4-ft. power cables with 8 AWG stranded wires and double-hole lugs: Black for -
48VDC and red for RTN. These cables should be used to connect the FortiGate-5144C PEMs to a FortiGate-5053B
power supply shelf. If the power cable length needs to be significantly longer than 4 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
l
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
l
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.
When connected to low-line AC power a minimum of 6 PSU-5000B power supplies are required to power a fully loaded
FortiGate-5144C chassis (that can require up to 6600W). Fortinet recommends the following low-line AC power
configurations to provide power to a FortiGate-5144C chassis:
Two FortiGate-5053B power supply shelves with a total of 8 PSU-5000Bs. One power supply shelf connects to
l
chassis power Feed A and the other to Feed B providing 6+2 redundancy.
A FortiGate-5053B and a FortiGate-5053B-L with a total of 8 PSU-5000Bs. One power supply shelf connects to
l
chassis Feed A and the other to Feed B providing 6+2 redundancy.
Two sets of a FortiGate-5053B and a FortiGate-5053B-L power supply shelves with a total 16 PSU-5000Bs
l
powered from 2 different AC power feeds and connected to both Feed A and Feed B to provide added redundancy.
