Selecting the power supplies and power converter trays that you need for your FortiGate-5050 configuration
This section provides some basic information for determining how many FortiGate-5053
power converter trays and FortiGate-5020/5050 power supplies that you need, depending
on the power requirements of your FortiGate-5050 chassis. This section provides
guidelines only. Actual requirements may vary depending on your installation
requirements. Contact Fortinet Technical Support if you need more information.
The FortiGate-5053 power converter tray contains space for up to three
FortiGate-5020/5050 power supplies. A FortiGate-5020/5050 power supply converts AC
power to -48 VDC power. Each FortiGate-5020/5050 power supply provides 800W of
power.
The FortiGate-5053 power converter tray uses 2 + 1 power supply redundancy. Ifthree
FortiGate-5020/5050 power supplies are installed in a FortiGate-5053 power converter
tray, the first two power supplies provide a total of 1600W (2x 800W) of power. The third
power supply is the redundant backup.
The maximum power output for a FortiGate-5053 power converter tray with FortiGate-
5020/5050 power supplies is 1600W; which can be achieved with two FortiGate-
5020/5050 power supplies. If you need 1600W of power and power supply redundancy,
you can add a third FortiGate-5020/5050 power supply.
Individual power requirements vary. If 800W is enough power and redundancy is not
required, you need one FortiGate-5053 power converter tray and one FortiGate-
5020/5050 power supply.
If 800W is sufficient but a redundant power supply is required, you can add a second
FortiGate-5020/5050 power supply. This second power supply will also cover power
requirements between 800 and 1600W. If you require redundant power greater than 800W
you can add a third FortiGate-5020/5050 power supply.
Basic power requirements
To supply enough power for a FortiGate-5050 chassis with a total of five FortiGate boards
and FortiSwitch boards you require one FortiGate-5053 power converter tray and two
FortiGate-5020/5050 power supplies (see Figure10). The FortiGate-5020/5050 power
supplies are installed in FortiGate-5053 slots 1 and 2. This configuration supplies 1600W
of power to the FortiGate-5020/5050 chassis.
Note: If your will not be filling all of the FortiGate-5050 slots you may not need both
FortiGate-5020/5050 power supplies.
