Mediant 4000 E-SBC
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 21

Mounting the chassis by attaching it directly to the 19-inch rack frame (posts) using
both the pre-installed front mounting brackets and the rear mounting brackets – see
Section
4.2.2 on page 21
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.
•
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.)
