Also visible on the front of the FortiGate-5140 chassis:
• Electrostatic discharge (ESD) socket, used for connecting an ESD wrist or ankle band
when working with the chassis.
• Front cable tray, used for managing and securing ethernet and other cables.
• Front accessible air filter.
• Three hot swappable FortiGate-5140 cooling fan trays.
FortiGate-5140 chassis back panel
Figure 2 on page 7
shows the back panel of the FortiGate-5140 chassis. The back panel
includes two hot-swappable redundant -48V/-60 VDC power entry modules (PEMs)
labelled A and B. Fortinet ships the FortiGate-5140 chassis with PEM A and B installed.
The PEMs provide redundant DC power connections for the FortiGate-5140 chassis and
distribute DC power to the chassis slots and to the fan trays.
Figure 2: FortiGate-5140 chassis back panel
If you require redundant power you should connect both PEMs to DC power. If redundant
power is not required, you should connect PEM A to DC power. Each PEM has four
-48V/-60 VDC connectors and 4 RTN connections. All eight of these connectors should be
connected to DC power.
Figure 2 on page 7
shows the terminal block cover removed from
PEM A and the wiring required to connect PEM A to DC power. While operating the
FortiGate-5140 both terminal block covers should be installed.
