Air Flow; Inserting Fortigate-5000 Series Boards And Rtm Modules - Fortinet FortiGate-5144C Manual

FortiGate-5144C hardware procedures
If you install the FortiGate-5144C chassis in a closed or multi-unit rack assembly, the operating ambient temperature of
the rack environment may be greater than room ambient temperature. Make sure the operating ambient temperature
does not exceed the manufacturer's maximum rated ambient temperature.
It is recommended that you mount the FortiGate-5144C chassis near the bottom of the rack to avoid making the rack
top-heavy and potentially falling over. If you are going to mount the chassis higher make sure the rack is well anchored.
Since the chassis is over 100 lbs use a lift to raise the chassis into position before mounting it.

Air flow

For rack installation, make sure that the amount of air flow required for safe operation of the FortiGate-5144C chassis is
not compromised. Make sure that the chassis ventilation openings at the top rear and the bottom front are not blocked
by cables or other components. The recommended minimum clearance at the front of the chassis is 100 mm and the
recommended clearance from the rear of the chassis is 60 mm. This results in a total footprint of 600 mm from front to
back. See Cooling fans, cooling air flow, and minimum clearance on page 20

Inserting FortiGate-5000 series boards and RTM modules

You can insert FortiGate and FortiSwitch-5000 series boards into the front of the FortiGate-5144C chassis and RTM
modules into the back of the chassis. Arrange the boards and modules in slots as required for your configuration.
FortiGate-5000 series boards can be installed in any FortiGate-5144C front panel slots. FortiController and FortiSwitch
boards can only be installed in switch slots 1 and 2. FortiController boards can also be installed in slots 3 and 4 for a dual
dual star configuration. FortiGate-5000 series RTM modules can be installed in any FortiGate-5144C RTM slot.
All FortiGate-5144C chassis are shipped with air baffle filler panels/cards on all but one front slot that include a warning
message to read the FortiGate-5000 documentation before installing your product. The temporary slot fillers must be
removed and all slots filled; either with FortiGate-5000 series boards or with air baffle slot fillers. Air baffle slot fillers are
similar to blank FortiGate-5000 boards and are required for proper cooling air flow.
FortiGate-5144C 6.2.3 Chassis Guide
The FortiGate-5144C chassis should not be operated as a free-standing appliance.
All FortiGate-5000 series boards must be protected from static discharge and physical shock.
Only handle or work with these boards at a static-free workstation. Always wear a grounded
electrostatic discharge (ESD) preventive wrist strap when handling these boards.
Do not operate the FortiGate-5144C chassis with open slots on the front panel or rear panel.
For optimum cooling performance and safety, front panel slots must contain a FortiGate-5000
series module or an air baffle slot filler and rear panel slots must either be covered or must
contain a rear transition module or slot filler.
