To connect the FortiGate-5144C PEMs to DC power you must use power connectors and wires that comply with the
local electrical wiring code and the requirements of the facility in which you are installing the FortiGate-5144C chassis.
The PEMs are hot-swappable, which means if both power feeds are connected you can remove and replace a defective
PEM while the chassis is operating. It is not necessary to notify the software or reset the system power to remove a
PEM. You can add, remove, or replace a second PEM without interrupting FortiGate-5144C operation.
Crimping guidelines
To connect the PEMs to data center power you should use 8 AWG or larger wires depending on the wire length and the
power requirements of your chassis. The ends of these wires must be fitted with 5/8-inch double-hole lugs suitable the
DC cables used, such as Thomas & Betts PN 54850BE. Use the following information to crimp and prepare these wires.
Do not crimp energized wires.
Follow these crimping guidelines:
l
Strip the insulation from cable. Be careful not to nick cable strands which may later result in stands breaking
l
Cable end should be clean: wire brush or clean with emery cloth if necessary. Insert cable into connector until it
stops. The insertion length must approximate the stripped length of cable
l
Insert connector in die and compress between the markings beginning near the tongue of the connector. Using the
wrong installing die may result in a defective connection.
l
After crimping, remove all sharp edges, flash or burrs.
