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. For example, if you are planning on connecting power zones 
1 and 2, you should use -48VDC and RTN connectors 1 and 2 on both PEM A and 
PEM B. You should not connect to power zone 1 of PEM A and power zone 2 of 
PEM B.

If a FortiGate-5140 chassis contains one FortiGate-5003 module it would be 
installed in logical slot 1 and receive power from power zone 2. You could also 
install two FortiGate-5001SX modules in logical slots 3 and 5 to also receive 
power from power zone 2. 

As a result, to supply power to this FortiGate-5140 configuration, you would need 
to supply power to power zone 2 for the FortiGate-5003 and the FortiGate-
5001SX modules.You would also need to supply power to power zone 1 or 3 to 
supply power to the fan trays.

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 a DC PEM 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 while the system maintains all routing information and 
ensures session preservation. 

The following procedure describes how to connect power to power zones 1 and 2 
of one PEM.

You need the following tools and equipment to connect a FortiGate-5140 PEM to 
Data Center DC power:

•

A number 2 Phillips screwdriver.

•

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

•

The required number of red and black AWG-14 stranded wires with terminal 
lugs attached.
