Selecting the power supplies and power supply shelves that you need for your
FortiGate-5140B chassis
This section provides some basic information for determining the power requirements of
your FortiGate-5140B chassis. Using these power requirements you can decide how
many PSU-5000B power supplies and FortiGate-5053Bpower supply shelves you need
to provide that power. This section provides guidelines only. Actual requirements may
vary depending on your installation requirements. Contact Fortinet Support if you need
more information.
The base FortiGate-5140B chassis (empty, with four fans, one shelf manager, two shelf
alarm modules and two PEMs installed and operating with the fans running at full speed)
requires a maximum of 530 W. Each chassis slot can supply up to 300 W. You can use
these numbers to estimate the power requirement for a chassis configuration.
Example: power for a chassis with 5 boards
For example, the power requirement for a FortiGate-5140B chassis with FortiGate,
FortiSwitch, or FortiController boards in five slots would be:
530 W + (300 W * 5) = 2030 W
If you are using high-line AC power, one PSU-5000B produces 2725W. Powering a
chassis with 5 boards would require one FortiGate-5053B power supply shelf connected
to one PEM. The power supply shelf would include one PSU-5000B unit. You can add a
second power supply for redundancy. If you want completely redundant power for the
chassis you can connect a second FortiGate-5053B unit to the other FortiGate-5140B
PEM and include one or two power supplies.
If you are using low-line AC power, one PSU-5000B produces 1200W. Powering a
chassis with 5 boards would require one FortiGate-5053B power supply shelf connected
to one PEM. The power supply shelf would include two PSU-5000B units. You can add a
third power supply for redundancy. If you want completely redundant power for the
chassis you can connect a second FortiGate-5053B unit to the other FortiGate-5140B
PEM and include two or three power supplies.
Example: power for a fully-loaded chassis (14 boards)
The power requirement for a fully loaded FortiGate-5140B chassis with boards in all 14
slots would be:
530 W + (300 W * 14) = 4730 W
If you are using high-line AC power, one PSU-5000B produces 2725W. Powering a
chassis with 14 boards would require one FortiGate-5053B power supply shelf
connected to one PEM. The power supply shelf would include two PSU-5000B units and
produce a total of 3450W. You can add a third power supply for redundancy. If you want
completely redundant power for the chassis you can connect a second FortiGate-5053B
unit to the other FortiGate-5140B PEM and include two or three power supplies.
If you are using low-line AC power, one PSU-5000B produces 1200W. Powering a
chassis with 14 boards would require one FortiGate-5053B power supply shelf
connected to one PEM. The power supply shelf would include four PSU-5000B units. If
you want redundant power for the chassis you can add a second FortiGate-5053B unit
connected to the other FortiGate-5140B PEM and include four power supplies.
