FortiGate-5140B
Power connection and
configuration
This chapter describes how to connect DC power to a FortiGate-5140B chassis.
The FortiGate-5140B chassis is designed to be installed in a data center or similar
location that has available -48VDC power fed from a 100A listed circuit breaker (also
called battery power or main DC power). Fortinet expects that most FortiGate-5140B
customers will be installing their chassis in a data center or similar location that is already
equipped with a -48VDC power system fed from a 100A listed circuit breaker that
provides power to existing networking or telecom equipment. The FortiGate-5140B
chassis is designed to be connected directly to this DC power system.
If DC power is not available at the location in which the FortiGate-5140B chassis is to be
installed you can use the FortiGate-5053B power converter shelf to convert AC to DC to
supply DC power to the FortiGate-5140B chassis.
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 convertor 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 considered.
If you are connecting your chassis to a local DC power source, use cables that meet your
local wiring codes. To connect the wires to the FortiGate-5140B PEMs use 3/4-inch
double-hole lugs with insulating boot suitable the DC cables used, such as Thomas &
Betts PN 256-30695-1225.
Green AWG-6 wires are recommended for ground connections (not supplied with the
chassis).
