Fortinet fortigate-5001a Hardwarehandbuch

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.

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 can connect the power in 
a number of configurations depending on the requirements of a particular 
installation.

Power zone 1 provides power to:

•

Fan Tray 0 and Fan tray 1

•

Slots 9, 11, 13 (see 

Power zone 2 provides power to:

•

Slots 1, 3, 5, 7 (see 

Power zone 3 provides power to:

•

Fan  tray  2

•

Slots 2, 4, 6, and 8 (see 

Power zone 4 provides power to:

•

Slots 10, 12, 14 (see 

•

Shelf manager

You can choose to connect power only to the power zones that you require. For 
example, if your FortiGate-5140 chassis contains a FortiSwitch-5003 module in 
slot 1 and four FortiGate-5001SX modules in slots 2, 3, 4, and 5 you would need 
to connect the following power zones:

•

Power zone 2 (for slots 1, 3, and 5)

•

Power zone 3 (for fan tray 2 and slots 2 and 4)

•

Power zone 4 (shelf manager)

This arrangement provides power to all occupied slots and should also provide 
enough cooling for this configuration. If you want more or redundant cooling, you 
can also connect power zone 1.
