This chapter describes how to connect data center DC power to a FortiGate-5140 chassis.
If data center DC power is not available, this document also describes how to use the
FortiGate-5053 power convertor tray to supply DC power to the FortiGate-5140 chassis.

Turning on FortiGate-5140 chassis power
The FortiGate-5140 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-5140 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-5140 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-5140 chassis is being installed.
Connect the FortiGate-5140 chassis to data center DC power using the redundant power
entry modules (PEMs) on the FortiGate-5140 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 PEM terminal strips. Connect all
eight of the terminals on the PEM terminal strips, four black -48VDC connections and four
red RTN connections.
Each FortiGate-5140 PEM includes 4 connectors that connect power to 4 different power
zones in the FortiGate-5140 chassis. Each power zone supplies power to different
FortiGate-5140 slots and cooling fan trays. You should always connect all 4 power zones.
If you are connecting both PEMs the -48VDC and RTN terminals on PEM A and PEM B
must be wired symmetrically. This means that the connections must be the same to both
PEMs.
FortiGate-5140 PEMs are hot-swappable, which means you can remove and replace a
defective PEM while the system is operating (assuming that the FortiGate-5140 system
has both PEMs connected for redundancy). It is not necessary to notify the software or
reset the system power. You can add, remove, or replace a second PEM without
interrupting FortiGate-5140 operation.
