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 2-5 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 (>16 Watts), we recommend the use of the CFM-8104A
Cooling Fan Module.
Ventilation and Cooling
This frame has been specifically engineered to minimize internal heat buildup and thus improve
module reliability. However, for long-term reliability and increased product life of the
DFR-8104A (without the Cooling Fan Module installed) and installed cards, it is recommended
that the total power requirements of all modules installed should not exceed 16 Watts, and to
leave an empty 1RU panel space above and below the frame for improved heat dissipation. For
information on the power dissipation of RossGear cards, contact your Ross Video sales
representative or visit our website.
For applications that require greater heat dissipation, or where the module power consumption is
greater than 16 Watts, we recommend the use of the DFR-8104A-C (with Cooling Fan Module
installed), or installation of the CFM-8104A Cooling Fan Module, field upgrade option. When
the Cooling Fan Module is installed, the frame can dissipate up to 40 Watts of module power.
Under these ventilated conditions, there is no requirement for extra spacing between the frames.
The DFR-8104A(-C) can be stacked one on top of the other, a feature that is highly desirable in
densely crowded rack frame environments.
Notice
— For reliable performance, it is recommended that the frame door not be
opened for longer than 5 minutes when using the Cooling Fan Module option, on
frames loaded with more than 16 Watts.
