AC in
The back panel also includes three AC power connectors, numbered 1, 2, 3. The AC connector numbering corresponds to the slot numbering showing in Figure 11. Each connector connects AC power directly to a FortiGate-5140 power supply. The FortiGate-5053 can contain 1, 2, or 3 FortiGate-5140 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 convertor trays that you need for your FortiGate-5140 configuration
This section provides some basic information for determining how many FortiGate-5053 power converter trays and FortiGate-5140 power supplies that you need, depending on the power requirements of your FortiGate-5140 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-5140 power supplies. A FortiGate-5140 power supply converts AC power to -48 VDC power. Each FortiGate-5140 power supply provides 1200W of power.
The FortiGate-5053 power converter tray uses 2 + 1 power supply redundancy. If three FortiGate-5140 power supplies are installed in a FortiGate-5053 power converter tray, the first two power supplies provide a total of 2400W (2 x 1200W) of power. The third power supply is the redundant backup.
The maximum power output for a FortiGate-5053 power converter tray with FortiGate-5140 power supplies is 2400W; which can be achieved with two FortiGate-5140 power supplies. If you need 2400W of power and power supply redundancy, you can add a third FortiGate-5140 power supply.
Individual power requirements vary. If 1200W is enough power and redundancy is not required, you require one FortiGate-5053 power converter tray and one FortiGate-5140 power supply.
If 1200W is sufficient but a redundant power supply is required, you can add a second FortiGate-5140 power supply. This second power supply will also cover power requirements between 1200 and 2400W. If you require redundant power greater than 1200W you can add a third FortiGate-5140 power supply.
