19-inch Rack Mounting

The device can be installed in a standard 19-inch rack by implementing one of the following
methods:
Placing it on a pre-installed shelf in a 19-inch rack (recommended method).
Attaching it directly to the rack's frame using the device's integral front mounting
brackets and the user-adapted rear mounting brackets (not supplied). This method is
required for racks that don't provide shelves.
When installing the chassis in a rack, implement the following safety
instructions:
To mount the device on a pre-installed shelf in the rack:
Place the device on a pre-installed shelf in the rack. It's recommended to attach the
device's integral front mounting brackets to the rack's frame to prevent it from sliding
off the shelf during cabling. Use standard 19-inch rack bolts (not provided) to fasten
the front of the device to the frame of the rack.
To install the device in a rack without shelves:
1. Position the device in a 19-inch rack and align the front and rear (see Section note
below) bracket holes to the holes (of your choosing) in the vertical tracks of the 19-inch
rack.
2. Use standard 19-inch rack bolts (not provided) to fasten the brackets to the frame of
the rack.

Rack Mount Safety Instructions
•
Elevated Operating 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 maximum ambient 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 over-current 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.)
If you are assembling the rear brackets, please note the following:
•
The distance between the screws on each bracket is 28 mm (1.1 inches).
•
To attach the brackets, use 4-40 screws with a maximal box penetration
length of 3.5 mm (0.14 inch).
