Figure 12: Back panel of the FortiGate-5053 power converter tray
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.
