Power connection and configuration
This chapter describes how to connect data center DC power to a FortiGate-5050 chassis.
If data center DC power is not available, this document also describes how to use the
FortiGate-5053 power converter tray to supply DC power to the FortiGate-5050 chassis.
This chapter describes:
•About data center DC power
•Connecting the FortiGate-5050 chassis to data center DC power and data center
ground
•Connecting the FortiGate-5050 chassis to AC power using the FortiGate-5053 power
converter tray
•Turning on FortiGate-5050 chassis power

About data center DC power

The FortiGate-5050 chassis is designed to be installed in a data center or similar location
that has available -48VDC power (also called battery power). Fortinet expects that most
FortiGate-5050 customers will be installing their FortiGate equipment in a data center or
similar location that is already equipped with a -48VDC power system that provides power
to existing networking or telecom equipment. The FortiGate-5050 chassis are designed to
be connected directly to this DC power system.
In this document, data center DC power refers to a -48VDC power system that is already
available at the location at which the FortiGate-5050 chassis is being installed.

Connecting the FortiGate-5050 chassis to data center DC power

and data center ground

Connect the FortiGate-5050 chassis to data center DC power using the redundant power
input connectors on the FortiGate-5050 back panel. Fortinet supplies and recommends
AWG-14 stranded wires for all power connections: Black for -48VDC and red for RTN.
Green AWG-6 wires are recommended for ground connections. If required, install terminal
lugs on the wires before connecting them to the power input connectors.

Connecting a FortiGate-5050 power input connector to data center DC power

The following procedure describes how to connect one FortiGate-5050 power input
connector to data center DC power. For normal operation, only power input connector A
must be connected. For redundant DC power you can connect power input connector B to
a different DC power source.
