The LEDs for each installed power supply are visible from the FortiGate-5053 power
converter tray front panel.
The back panel of the FortiGate-5053 (shown in Figure9) includes one DC power
connector terminal consisting of a RTN connector and a -48VDC connector.
• The -48VDC connector is labelled V- and may also be labelled with -48V (BLACK).
• The RTN connector is labelled V+ and may also be labelled RTN (RED)

The back panel also includes three AC power connectors numbered 1, 2, 3. The AC
connector numbering corresponds to the slot numbering showing in Figure8 . 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.

LED State Description
AC Power Green The power supply is connected to AC power.
Off The power supply is not receiving DC power. This can happen if an AC
cable is not connected, if the power supply is not correctly installed in
the slot, or if the power supply is not functioning.
DC Power Green The power supply is providing DC power.
Off The power supply is not providing DC power. If the AC power LED is lit
and the DC power LED is not, the power supply is not functioning
correctly and should be replaced. This LED can also go off if the power
supply overheats. If this happens the power supply stops supplying DC
power. After the power supply cools down in will start supplying DC
power again and this LED lights.
