The FortiGate-5050 chassis must be mounted in a standard 19-inch rack. The chassis
requires 5U of vertical space in the rack.
If you install the FortiGate-5050 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.

Air flow

For rack installation, make sure that the amount of air flow required for safe operation of
the FortiGate-5050 chassis is not compromised.

Inserting 5000 series boards into a FortiGate-5050 chassis

You can insert FortiGate-5000 series and FortiSwitch boards into the FortiGate-5050
chassis. Arrange the boards in slots as required for your configuration. FortiGate-5000
series boards can be installed in any FortiGate-5050 slots. FortiSwitch-5003 boards can
only be installed in switch slots 1 and 2.
Your FortiGate-5050 chassis may have been shipped with temporary slot filler panels 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.

Note: Mount the FortiGate chassis before installing the FortiGate-5000 series boards.

Caution: The FortiGate-5050 chassis should not be operated as a free-standing appliance.
