Connecting a FortiGate-5140 chassis to Data Center DC power and Data Center ground
Connect the FortiGate-5140 chassis to Data Center DC power (also called battery
power) using the redundant power entry modules (PEMs). Fortinet supplies and
recommends AWG-14 stranded wires for all power connections. Black for
-48VDC, red for RTN, and green for ground. If required, install terminal lugs on the
wires before connecting them to the PEM terminal strips. If you are connecting
both PEMs the -48VDC and RTN terminals on PEM A and PEM B must be wired
symmetrically.
