Fortinet 5140-R manual Connecting the FortiGate-5140 chassis to data center ground

Power connection and configuration

To connect a FortiGate-5140 PEM to data center DC power

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 terminal block cover from the FortiGate-5140 PEM.

3Connect the DC power wires (see Figure 9):

•Connect a black -48V power wire from the data center DC power source to connector 1 on the FortiGate-5140 PEM terminal strip labeled -48V/-60 VDC nom.

•Connect a black -48V power wire from the data center DC power source to connector 2 on the FortiGate-5140 PEM terminal strip labeled -48V/-60 VDC nom.

•Connect a black -48V power wire from the data center DC power source to connector 3 on the FortiGate-5140 PEM terminal strip labeled -48V/-60 VDC nom.

•Connect a black -48V power wire from the data center DC power source to connector 4 on the FortiGate-5140 PEM terminal strip labeled -48V/-60 VDC nom.

•Connect a red RTN return wire from data center RTN to connector 1 on the FortiGate-5140 PEM terminal strip labeled RTN.

•Connect a red RTN return wire from data center RTN to connector 2 on the FortiGate-5140 PEM terminal strip labeled RTN.

•Connect a red RTN return wire from data center RTN to connector 3 on the FortiGate-5140 PEM terminal strip labeled RTN.

•Connect a red RTN return wire from data center RTN to connector 4 on the FortiGate-5140 PEM terminal strip labeled RTN.

4Secure the power cabling to the chassis using tie wraps and the back cable tray.

5If required, label the black wires -48V.

6If required, label the red wires RTN.

7Re-attach the terminal block cover to the FortiGate-5140 PEM.

Connecting the FortiGate-5140 chassis to data center ground

The FortiGate-5140 chassis includes a ground terminal on the lower left side of the FortiGate-5140 back panel (see Figure 2 on page 7). The shelf ground terminal provides two M6 bolts to connect a double-lug ground terminal cable. This connector must be connected to data center ground.

You need the following tools and equipment to connect the FortiGate-5140 chassis to ground:

•A number 2 Phillips screwdriver.

•An electrostatic discharge (ESD) preventive wrist or ankle strap with connection cord.

•One green AWG-6 stranded wire with terminal lug with 45° angle tongue attached.
