Rack Mount Safety Instructions
When installing the chassis in a rack, ensure you implement the following
safety instructions:
• Elevated Operating Ambient Temperature: If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient temperature. Therefore,
consideration should be given to installing the equipment in an
environment compatible with the device's maximum ambient operating
temperature (Tma) of 40°C (104°F).
• Reduced Air Flow: Installation of the equipment in a rack should be
such that the amount of air flow required for safe operation on the
equipment is not compromised.
• Mechanical Loading: Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven
mechanical loading.
• Circuit Overloading: Consideration should be given to the connection of
the equipment to the supply circuit and the effect that overloading of the
circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be
used when addressing this concern.
• Reliable Earthing: Reliable earthing of rack-mounted equipment should
be maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (e.g., use of power
strips.)
¾ To install the device in a 19-inch rack:
1. Position the device in a 19-inch rack, aligning the left and right mounting bracket holes
with the holes in the vertical tracks of the 19-inch rack.
2. Using standard 19-inch rack bolts (not supplied), fasten the device to the frame of the
rack. Note that optional rear and mid-attachment is supported.
