To connect a FortiGate-5050 power input connector to data center DC power
You need the following tools and equipment to connect a FortiGate-5050 power input
connector to data center DC power:
• 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.
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.
3Insert the black -48V and red RTN wires through the power wire fixture (see Figure6).
4Connect the black -48V power wire from the data center DC power source to the
terminal on the FortiGate-5050 power input connector labelled (-DC in).
5Connect the red RTN return wire from data center RTN to the terminal on the
FortiGate-5050 power input connector labelled RTN.
6Make sure the power wires are secured to the chassis using the power wire fixture and
tie wraps if required.
7If required, label the black wire -48V.
8If required, label the red wire RTN.
9Re-attach the protection plate to the FortiGate-5050 power input connector.
