The Firebox M4600 rack mount system includes:
Rack rail kit
• 4 L-shaped brackets
• 2 sliding rails

• 12 flat countersink screws and 12 conical washers (C)
• 2 front ear brackets and 6 small screws
Precautions
When you install the Firebox in a rack, consider these factors:
Elevated Operating Ambient Temperature
If you install the Firebox in a closed or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient. Make sure the ambient temperature of
the rack environment is within the certified operating range specified in the Hardware Guide.
Reduced Air Flow
When you install the Firebox in a rack, make sure that the amount of air flow required for safe
operation of the equipment is not compromised.
Mechanical Loading
When you mount the Firebox in the rack, avoid hazardous conditions caused by uneven mechanical
loading.
Circuit Overloading
Make sure you connect the Firebox to the power supply circuit in such a way that there is no
overloading of the circuits, and no impact on overcurrent protection and supply wiring.
Reliable Grounding
Make sure all rack-mounted equipment is correctly grounded. For example, make sure you use
power strips instead of direct connections to the branch circuit.
CAUTION: Do not use your slide/rail mounted Firebox as a shelf or work space.
