Installing the Frame Power Supply
The power supply tray plugs into the right-hand section of the chassis. The supply is universal,
and no power adjustments are required.
Use the following procedure to install the power supply:
1.
Carefully unpack the power supply from its box, and retain all packing material for
future use, if required.
2.
Align the card-edge on the top and bottom of the supply with the slots in the chassis.
3.
Push the power supply in firmly to ensure a tight connection at the rear of the frame.
This completes the procedure for installing the power supply.
Fault Reporting
The error conditions listed in Table 2.1 will trigger the SMPTE 269M fault reporting circuit, and
the signal will be sent to Aux A on the back of the frame. Refer to the section “ Aux A
Connector ” on page 2-6 for details.
Improving Performance
To improve performance and reliability, the PS-8102 has an on-board fan. For even better
reliability, and high load conditions (>40 Watts), we recommend the use of the CFM-8110A
Cooling Fan Module.
Ventilation and Cooling
This frame has been specially engineered to minimize internal heat buildup and thus improve
module reliability. However, for long-term reliability and increased product life of the
DFR-8110A, it is recommended that the total power dissipation of all modules installed should
not exceed 40 Watts, and to leave an empty 1RU panel space above and below the frame for
improved heat dissipation. For information on the power requirements of RossGear modules,
please refer to the Ross Video Product Catalog or visit our website.
It is also recommended for applications using less than 40 Watts in a non-ventilated frame, but
where the individual module power consumption is greater than 8 Watts, that the cards be evenly
distributed in the frame. This measure will prevent the creation of concentrated heat, or
unbalanced heat-rise areas, in the frame.
For applications that require greater heat dissipation, or where the module power consumption is
greater than 40 Watts, we recommend the use of the DFR-8110A-C, or installation of the
CFM-8110A Cooling Fan Module in a DFR-8110A, field upgrade option. When the Cooling Fan
Module is installed, the frame and PS-8102 can supply up to 80 Watts of module power. Under
these ventilated conditions, there is no requirement for extra spacing between the frames. The
DFR-8110A-C (or DFR-8110A with CFM-8110A option) can be stacked one on top of the other,
a feature that is highly desirable in densely crowded rack frame environments.
Warning Hazardous Voltages
— The safe operation of this product requires
that a protective earth connection be provided. This protective earth is provided by
the grounding conductor in the equipment’s supply cord. To reduce the risk of
electrical shock to the operator and service personnel, this ground connector must be
connected to an earthed ground.
