The back panel also includes three AC power connectors numbered 1, 2, 3. The AC
connector numbering corresponds to the slot numbering showing in Figure10. Each
connector connects AC power directly to a FortiGate-5020/5050 power supply. The
FortiGate-5053 can contain 1, 2, or 3 FortiGate-5020/5050 power supplies depending on
your requirements. You should only connect AC power to the power supplies that are
installed.
AC input power characteristics:
• AC input voltage: 110 to 250 VAC
• AC input current: 10A
• Frequency: 47 to 63 Hz
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
modules and FortiSwitch modules you require one FortiGate-5053 power converter tray
and two FortiGate-5020/5050 power supplies (see Figure12). 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.
