Physical Installation

Standalone

To use the USR4204 on a flat, horizontal surface, affix the four adhesive rubber feet to the

bottom of the housing in the four corners.

Rack Mounting

To mount the USR4204 in a 19" rack, securely fasten the two rackmount brackets to the

sides of the USR4204 using the supplied hardware and mount the USR4204 in a 1U space in

a 19" rack.

CAUTION: When the USR4204 is installed in a closed or multiunit

rack assembly, be aware of these potentially hazardous situations:

 Elevated Ambient Operating Temperature – A USR4204 installed in a closed or multi-

unit rack assembly may be subjected to an ambient operating temperature that

exceeds room ambient temperature. Installing the equipment in an environment

compatible with the maximum ambient temperature (Tmax) specified by the

manufacturer is recommended.

 Reduced Air Flow – Ensure that the amount of airflow required for safe operation of

the equipment is not compromised when a USR4204 is installed in a rack assembly.

 Mechanical Loading – Do not create a hazardous condition by mounting the USR4204

in a rack that results in uneven or unbalanced 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. Careful assessment and

awareness of equipment nameplate ratings should be used.

 Reliable Earthing/Grounding - Reliable earthing/grounding 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).
