2 - 4 ONline 17-Slot System Concentrator Installation and Operation Guide
Site Selection Considerations
The concentrator can be placed almost anywhere within your company,
including offices and computer rooms. In general, we recommend
installation in a wiring closet. The unit has been designed for rack
mounting and comes with all the necessary hardware.
Location Requirements
The area where you install the ONline System Concentrator must meet the
following conditions:
❑ Temperature between 0° to 50° C (32° to 122° F)
❑ Relative humidity less than 95%, non-condensing
❑ AC power source within 6 feet (2 meters). Note that for installation
to have true backup power, two independent AC power sources are
required
❑ The table or rack where the unit is installed should be level and not in
direct sunlight or in an excessively dusty location
Ventilation
The concentrator fan units draw air in through the front and bottom of the
chassis and exhausts air out the back. Make sure there are at least 6 inches
(15 centimeters) between the fan vents at the back of the unit and the
nearest surface to allow adequate airflow for cooling. This minimum
distance is also required for access to the rear of the unit for maintenance.
The cable tray that comes standard with the concentrator helps prevent a
tangle of cables at the front of the concentrator and also permits the
required airflow to the unit. Make sure the cable tray is installed below the
unit correctly before installing the concentrator.
