Environmental Requirements
The 833IS is designed to operate in a normal office environment. The following
condition must be met and maintained.
Placement The 833IS is designed for either 19" rack mount or table top placement.
Locate the 833IS in an area where:
■
Power cord and cables are out of traffic areas.
■
The front panel is accessible.
Sufficient clearances must be maintained at both sides of the unit to allow proper air
flow to the internal fans.
For rack mounting, the 833IS requires 1.5 rack mount spaces (i.e. the 833IS height
is 1.5U). It is not necessary to leave empty spaces above or below the unit in the
rack.
Mounting of the equipment in the rack shall be such that a hazardous condition does
not occur due to uneven mechanical loading. Heavier equipment should be located
at the bottom of the rack, and the rack should be loaded such that the bottom slots
are used first (fill from the bottom up).
Circuits supplying power to the rack must be sufficient to safely supply power to all
equipment within the rack based on the equipment nameplate rating. Power
distribution to all equipment in the rack must have proper grounding. Particular
attention should be given to supply connections other than direct connections to the
branch circuit (e.g. power strips).
