Note
In case of a power supply failure, contact your openGear TM
dealer.
The PS-8300 is a power factor corrected supply, capable of working with all world AC standards
(100-240V). The supply has an indicator LED on the front, and an error detection circuit that will
indicate the conditions described in Table 1.
Table 1. Status LED Descriptions
LED Color Display and Description
Fault Red When lit, an alarm condition is occurring on a card. (CFM-8310 option)
Fan Fail Red When lit, a fan on the frame door or PS-8300 is stalled. (CFM-8310 option)
Power
Supply Green/
Red
When lit green, the PS-8300 is operating normally.
When flashing red:
•
there is an output over or under voltage condition on the PS-8300
•
there is no A/C; assumed that the second supply is operating
normally
Fault Reporting
If the optional CFM-8310 module is installed, the error conditions listed in Table 1 above will trigger
the SMPTE 269M fault reporting circuit, and the signal will be sent to the Fault BNC on the back of
the frame. Refer to the section “Fault Report Connector” in this chapter and the chapter, “SMPTE
269M Fault Reporting Option” for further details.
Improving Performance
To improve performance and reliability, the PS-8300 has an on-board fan. Under high load conditions
(>40 Watt), the optional CFM-8310 Cooling Fan Module must be added for increased ventilation.
Ventilation and Cooling
This frame has been specially engineered to minimize internal heat buildup and thus improve card
reliability. However, for long-term reliability and increased product life of the 8310 frame (without the
Cooling Fan Module installed), it is recommended that the total power dissipation of all cards installed
in the frame should not exceed 40 Watt, and to leave an empty 1RU panel space above and below the
frame for improved heat dissipation. For information on the power dissipation of openGear
TM cards,
please refer to the openGear TM Product Catalog or visit our website.
For applications using less than 40 Watt in a non-ventilated frame, but where the individual card power
consumption is greater than 8 Watt, the cards should be evenly distributed in the frame. This 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 card power consumption is greater
than 40 Watt, it is necessary to use the 8310-C frame (with Cooling Fan Module installed), or to install
the CFM-8310 Cooling Fan Module field upgrade option. When the Cooling Fan Module is installed,
the frame and PS-8300 can supply up to 120 Watt of card power. Under these ventilated conditions,
there is no requirement for extra spacing between the frames. The 8310-C (or 8310 with CFM-8310
option) can be stacked one on top of the other, a feature that is highly desirable in densely crowded
rack frame environments.
