This chapter provides instructions on unpacking, mounting, and connecting your Unity 550
as well as connector information including detailed pinouts.
2.1 Unpacking and Inspection
Carefully unpack the unit and its ac power cord and inspect for obvious signs of physical
damage that might have occurred during shipment. Any damage claims must be reported to
the carrier immediately. Be sure to check the package contents carefully for important
documents and materials.
Note:
2.2 Location and Mounting
The Unity 550 may be mounted in a standard 19-inch equipment rack or set up for desktop
operation. In either location, maintain a clean, dry environment for the Unity 550 .
Precautions
FCC-Mandated Suppression of Radio Frequency Emissions
WA RNING
This is a Class A product. In a domestic environment this product may cause radio
interference for which the user may need to take mitigating action.
If the Ethernet port has a cable connected to it, that cable must be properly shielded and
grounded to minimize RF emissions that could interfere with nearby equipment.
DANGE R
To avoid damage to the Unity 550 unit and other equipment, or personal injury, the following
items should be strictly observed.
Elevated Ambient Operating Temperatures in Rack-Mounted Units
When equipment is installed in a closed or multi-unit rack assembly, the ambient operating
temperature of the rack environment may be greater than the room's ambient temperature.
Therefore, consideration should be given to the ambient air temperature within the rack (not
just inside the room) when deciding if the maximum recommended ambient operating
temperature (TMRA) is met or exceeded.
Reduced Air Flow
Equipment should be installed such that the airflow required for safe operation of the
equipment is not compromised. The Unity 550 may be arranged in a rack without empty
spaces between units, if heat buildup is prevented by ensuring that the side vents remain
unblocked, and that there is adequate clearance around the vent holes.
Mechanical Loading
Rack-mounted equipment should be installed in such a way that a hazardous condition is
not produced by uneven loading. The Unity 550 unit is not very heavy, but total rack loading
must be considered. Also, do not rest any unsupported equipment on a rack-mounted Unity
unit.

Please save the packing materials and original shipping containers in case you
must later return the unit for repair. Packing these units in other containers in such a
way that they are damaged will void your warranty.
