To connect a FortiGate-5140 PEM to data center DC power
1 Attach the ESD wrist strap to your wrist and to an ESD socket or to a bare metal
surface on the chassis or frame.
2 Loosen the screws and remove the terminal block cover from the FortiGate-5140 PEM.
3 Connect 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.
4 Secure the power cabling to the chassis using tie wraps and the back cable tray.
5 If required, label the black wires -48V.
6 If required, label the red wires RTN.
7 Re-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.
