Installing the System into a Rack Cabinet
Rackmount Instructions
To mount the “DNA1120XXXXXXXXXXXXXXX” in any standard-sized ,
272 mm wide, 1U high rack, follow these instructions:
1. Place the “DNA1120XXXXXXXXXXXXXXX” on a hard flat surface with
the front panel facing you.
2. Attach a rack–mount bracket to one side of the
“DNA1120XXXXXXXXXXXXXXX” with the supplied screws. Then attach
the other bracket to the other side.
3. Make sure the brackets are properly attached to the
“DNA1120XXXXXXXXXXXXXXX”.
4. Use the appropriate screws (not included) to securely attach the brackets
to your rack.
5. Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, consideration should be
given to installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) specified by the manufacturer.
6. Reduced Air Flow - Installation of the equipment in a rack should be
such that the amount of air flow required for safe operation of the
equipment is not compromised.
7. Mechanical Loading - Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven mechani-
cal loading.
8. 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. Ap-
propriate consideration of equipment nameplate ratings should be used
when addressing this concern.
9. Reliable Earthing - Reliable earthing of rack-mounted equipment should
be maintained. Particular attention should be given to supply connec-
tions other than direct connections to the branch circuit (e.g. use of
power strips).”
Important:
Make sure you use the screws supplied with the mounting brack-
ets. Using the wrong screws could damage the
“DNA1120XXXXXXXXXXXXXXX” and would invalidate your
warranty.
