4.2 19-Inch Rack Mounting
The device is designed to fit into a 19-inch industrial rack of 1 rack-unit height (1U). You
can mount it in the rack using any one of the following mounting options:

( Recommended ) Mounting the chassis on a pre-installed shelf in a 19-inch rack – see
Section 4.2.1 on page 31

Mounting the chassis by attaching it directly to the 19-inch rack frame (posts) using
both the front- and the rear-mounting brackets – see Section
4.2.2 on page 32
Rack Mount Safety Instructions
When installing the chassis in a rack, implement the following 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 (T
A
) 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.
