Connecting a FortiGate-5050 chassis to the FortiGate-5053 power converter tray
To use a FortiGate-5053 power converter tray with the FortiGate-5050 chassis you need
to make DC power connections between the FortiGate-5050 chassis and the FortiGate-
5053 power converter tray. You also need to the connect the FortiGate-5050 chassis to
data center ground.
To connect a FortiGate-5050 power input connector to a FortiGate-5053 power
converter tray
The following procedure describes how to connect one FortiGate-5050 power input
connector to a FortiGate-5053 power converter tray. For normal operation, only one power
input connector must be connected. For redundant chassis DC power you can connect the
second power input connector to a second FortiGate-5053 power converter tray.
You need the following tools and equipment to connect a FortiGate-5020/5050 power
input connector to a FortiGate-5053 power converter tray:
• A number 2 Phillips screwdriver.
• An electrostatic discharge (ESD) preventive wrist or ankle strap with connection cord.
• One black AWG-14 stranded wire with terminal lugs attached and labelled -48V.
• One red AWG-14 stranded wire with terminal lugs attached and labelled RTN.
• A FortiGate-5053 power converter tray containing two or three FortiGate-5020/5050
power supplies and mounted in a rack near the FortiGate-5050 chassis.
1Attach the ESD wrist strap to your wrist and to an ESD socket or to a bare metal
surface on the chassis or frame.
2Loosen the screws and remove the protection plate from the FortiGate-5050 power
input connector.
3If required, loosen the screws and remove the clear plastic cover from the back of the
FortiGate-5053 power converter tray.
4Insert the black -48V and red RTN wires through the power wire fixture (see Figure14).
5Connect the black -48V power wire from the FortiGate-5053 power converter tray V-
terminal (the right connector) to the terminal on the FortiGate-5050 power input
connector labelled (-DC in).
6Connect the red RTN return wire from the FortiGate-5053 power converter tray
unmarked connector (the left connector) to the terminal on the FortiGate-5050 power
input connector labelled RTN.
Caution: The FortiGate-5053 power converter tray should not be connected to AC power
until specified in the following procedure.
